series which clean up the implementation:
- "refine mas_mab_cp()"
- "Reduce the space to be cleared for maple_big_node"
- "maple_tree: simplify mas_push_node()"
- "Following cleanup after introduce mas_wr_store_type()"
- "refine storing null"
- The series "selftests/mm: hugetlb_fault_after_madv improvements" from

Oscar Salvador implements a bunch of consolidations and cleanups in the
hugetlb code.
- The series "Do not shatter hugezeropage on wp-fault" from Dev Jain
takes away the wp-fault time practice of turning a huge zero page into
small pages. Instead we replace the whole thing with a THP. More
consistent cleaner and potentiall saves a large number of pagefaults.
- The series "percpu: Add a test case and fix for clang" from Andy
Shevchenko enhances and fixes the kernel's built in percpu test code.
- The series "mm/mremap: Remove extra vma tree walk" from Liam Howlett
optimizes mremap() by avoiding doing things which we didn't need to do.
- The series "Improve the tmpfs large folio read performance" from
Baolin Wang teaches tmpfs to copy data into userspace at the folio size
rather than as individual pages. A 20% speedup was observed.

asm-generic updates for 6.13
These are a number of unrelated cleanups, generally simplifying the
architecture specific header files:
- A series from Al Viro simplifies asm/vga.h, after it turns out that
most of it can be generalized.
- A series from Julian Vetter adds a common version of
memcpy_{to,from}io() and memset_io() and changes most architectures
to use that instead of their own implementation
- A series from Niklas Schnelle concludes his work to make PC
style inb()/outb() optional
- Nicolas Pitre contributes improvements for the generic do_div()
helper
- Christoph Hellwig adds a generic version of page_to_phys()
and phys_to_page(), replacing the slightly different architecture
specific definitions.
- Uwe Kleine-Koenig has a minor cleanup for ioctl definitions

First step of consolidating the VDSO data page handling:
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various mechanisms
and fail to provide a clear separation of the functionalities.
Clean this up by:
* consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
* removing the last includes of header files which are pulling in other
headers outside of the VDSO namespace.
* seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every architecture
add support seperately.

m68k: mcfgpio: Fix incorrect register offset for CONFIG_M5441x
Fix a typo in the CONFIG_M5441x preprocessor condition, where the GPIO
register offset was incorrectly set to 8 instead of 0. This prevented
proper GPIO configuration for m5441x targets.

asm-generic: introduce text-patching.h
Several architectures support text patching, but they name the header files that declare patching functions differently. Make all such headers consistently named text-patching.h and add an empty header in asm-generic for architectures that do not support text patching.

m68k: Make sure NR_IRQS is never zero
When compiling an MMU kernel without any platform support, e.g.
"MMU=y allnoconfig":
echo CONFIG_MMU=y > allno.config
make KCONFIG_ALLCONFIG=1 allnoconfig
NR_IRQS is zero, causing a build failure:
kernel/irq/irqdesc.c:593:3: error: array index in initializer exceeds array bounds
593 | [0 ... NR_IRQS-1] = {
| ^
kernel/irq/irqdesc.c:593:3: note: (near initialization for ‘irq_desc’)
kernel/irq/irqdesc.c:593:22: warning: excess elements in array initializer
593 | [0 ... NR_IRQS-1] = {
| ^
kernel/irq/irqdesc.c:593:22: note: (near initialization for ‘irq_desc’)
Fix this by setting the default value of NR_IRQS to 8, which is the
mininum number of interrupts on any m68k CPU (the DIP48 variant of the
MC68008 has tied IPL0 and IPL2 together, but that does not impact the
range).

m68k: mvme147: Fix SCSI controller IRQ numbers
Sometime long ago the m68k IRQ code was refactored and the interrupt
numbers for SCSI controller on this board ended up wrong, and it hasn't
worked since.
The PCC adds 0x40 to the vector for its interrupts so they end up in
the user interrupt range. Hence, the kernel number should be the kernel
offset for user interrupt range + the PCC interrupt number.

asm-generic: provide generic page_to_phys and phys_to_page implementations
page_to_phys is duplicated by all architectures, and from some strange reason placed in <asm/io.h> where it doesn't fit at all. phys_to_page is only provided by a few architectures despite having a lot of open coded users. Provide generic versions in <asm-generic/memory_model.h> to make these helpers more easily usable. Note with this patch powerpc loses the CONFIG_DEBUG_VIRTUAL pfn_valid check.

clone3: drop __ARCH_WANT_SYS_CLONE3 macro
When clone3() was introduced, it was not obvious how each architecture deals with setting up the stack and keeping the register contents in a fork()-like system call, so this was left for the architecture maintainers to implement, with __ARCH_WANT_SYS_CLONE3 defined by those that already implement it. Five years later, we still have a few architectures left that are missing clone3(), and the macro keeps getting in the way as it's fundamentally different from all the other __ARCH_WANT_SYS_* macros that are meant to provide backwards-compatibility with applications using older syscalls that are no longer provided by default. Address this by reversing the polarity of the macro, adding an __ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3 from all the other ones.

arch: Rename fbdev header and source files
The per-architecture fbdev code has no dependencies on fbdev and can be used for any video-related subsystem. Rename the files to 'video'. Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE. On arc, arm, arm64, sh, and um the asm header file is an empty wrapper around the file in asm-generic. Let Kbuild generate the file. The build system does this automatically. Only um needs to generate video.h explicitly, so that it overrides the host architecture's header. The latter would otherwise interfere with the build. Further update all includes statements, include guards, and Makefiles. Also update a few strings and comments to refer to video instead of fbdev. v3: - arc, arm, arm64, sh: generate asm header via build system (Sam, Helge, Arnd) - um: rename fb.h to video.h - fix typo in commit message (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Cc: Vineet Gupta <vgupta@kernel.org> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> Cc: Huacai Chen <chenhuacai@kernel.org> Cc: WANG Xuerui <kernel@xen0n.name> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Cc: "James E.J.

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.

against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".

series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.

fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.

- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.

crash out from kexec and clean up related config items".

"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.

Introduce cpu_dcache_is_aliasing() across all architectures
Introduce a generic way to query whether the data cache is virtually
aliased on all architectures. Its purpose is to ensure that subsystems
which are incompatible with virtually aliased data caches (e.g. FS_DAX)
can reliably query this.
For data cache aliasing, there are three scenarios dependending on the
architecture. Here is a breakdown based on my understanding:
A) The data cache is always aliasing:
* arc
* csky
* m68k (note: shared memory mappings are incoherent ? SHMLBA is missing there.)
* sh
* parisc
B) The data cache aliasing is statically known or depends on querying CPU
state at runtime:
* arm (cache_is_vivt() || cache_is_vipt_aliasing())
* mips (cpu_has_dc_aliases)
* nios2 (NIOS2_DCACHE_SIZE > PAGE_SIZE)
* sparc32 (vac_cache_size > PAGE_SIZE)
* sparc64 (L1DCACHE_SIZE > PAGE_SIZE)
* xtensa (DCACHE_WAY_SIZE > PAGE_SIZE)
C) The data cache is never aliasing:
* alpha
* arm64 (aarch64)
* hexagon
* loongarch (but with incoherent write buffers, which are disabled since

asm-generic cleanups for 6.8
A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems. This series notably contains a patch from Jiaxun Yang that converts MIPS to use asm-generic/io.h like every other architecture does, enabling future cleanups. Some of my own patches fix -Wmissing-prototype warnings in architecture specific code across several architectures. This is now needed as the warning is enabled by default. There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another. David McKay fixes a bug in __generic_cmpxchg_local() when this is used on 64-bit architectures. This could currently only affect parisc64 and sparc64. Additional cleanups address from Linus Walleij, Uwe Kleine-König, Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies between architectures. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmWeak8ACgkQYKtH/8kJ UidSiQ/+LL1WTO9d3Zx5HI0GGGjaIYpYs6jUNSf9Y5GPQiOrvjfEWj7CU11/4vxl GlQRpRyncYm8Eiz0Qu+aNxZFiiMah8Uful75yfbX8P1L4EPTbAYNDjkyNJrTjIAK jPK4sl8awIrapOeFUz++PsEj22R/4Is4f0mo+CqoCkL5RKlHe5oFdXzcwjmds4yK CvU6Ldn+M7FZ3EItMdjXaB3D3HS9uictFiO5JByZY8p+IcqgNRI/iHNnZIMsltJ+ XjDi0DG+x4jCj6teElSchw7AofE4OcNSP3xbR1PLKv6+xBLGYaAGZhNuPTz88eV/ Gj0loDQrrR5McGUfDBRHK9zN2Jd0O/FKnfh9kLOt1FLFyGPvC78Q/2HkpVCjbBr2 Pr1aqhLDHA+tGNSsThsV8RUa8/tiEnxAki43tfBFS3SEKhtQsTm2g1z4miwbE3p0 BJIrSgTqrP/SBq7a9z/thPrkzdZcNuA9FUETTbaMeUlJS51n1V9E5A1t7sOG7jaI vV/gbuR6FjvD49mTyQiOSCt3V4ygRqgN1Q+C4QM8WLqq2keUq0AhGodquv8F78in J3x2j2r27lHY7jKf8B0dua/JXAsF20u8qD6yDQ9ymkjt/MWhGXBgK0jpT7RTIuMS e2jmTywUVD4UohAcx3inkOojUhIJ5KDB0I4Pzv4zWcHNbyFNKcY= =4VQl -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic cleanups from Arnd Bergmann: "A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems.

header cleanups for 6.8
The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations.

mm: Introduce flush_cache_vmap_early()
The pcpu setup when using the page allocator sets up a new vmalloc mapping very early in the boot process, so early that it cannot use the flush_cache_vmap() function which may depend on structures not yet initialized (for example in riscv, we currently send an IPI to flush other cpus TLB). But on some architectures, we must call flush_cache_vmap(): for example, in riscv, some uarchs can cache invalid TLB entries so we need to flush the new established mapping to avoid taking an exception. So fix this by introducing a new function flush_cache_vmap_early() which is called right after setting the new page table entry and before accessing this new mapping. This new function implements a local flush tlb on riscv and is no-op for other architectures (same as today).

arch/*/io.h: remove ioremap_uc in some architectures
ioremap_uc() is only meaningful on old x86-32 systems with the PAT extension, and on ia64 with its slightly unconventional ioremap() behavior. So remove the ioremap_uc() definition in architecutures other than x86 and ia64. These architectures all have asm-generic/io.h included and will have the default ioremap_uc() definition which returns NULL. This changes the existing behaviour, while no need to worry about any breakage because in the only callsite of ioremap_uc(), code has been adjusted to eliminate the impact. Please see atyfb_setup_generic() of drivers/video/fbdev/aty/atyfb_base.c. If any new invocation of ioremap_uc() need be added, please consider using ioremap() intead or adding a ARCH specific version if necessary.

m68knommu: fix compilation for ColdFire/Cleopatra boards
The ColdFire based Cleopatra family of boards use mostly the same
external pin arrangements as the NETtel board family. The build uses the
NETtel specific code as needed, but not all the conditional defines
allow for this. If you have the CONFIG_NETtel config option set
everything compiles as expected, but if you only select the
CONFIG_CLEOPATRA board type then you will get compile failures:
arch/m68k/coldfire/nettel.c: In function ‘nettel_smc91x_init’:
arch/m68k/coldfire/nettel.c:126:2: error: implicit declaration of function ‘mcf_setppdata’; did you mean ‘xas_set_update’? [-Werror=implicit-function-declaration]
mcf_setppdata(0, 0x0080);
^~~~~~~~~~~~~
xas_set_update
Fix the nettel.h include conditional checks to cover all board types.
This also means some code paths need to check for the 5407 SoC - since
one of the Cleopatra board types is based on that. It is very similar
to the 5307 specific code, and it can use that "as-is".

m68k: implement xor_unlock_is_negative_byte
Using EOR to clear the guaranteed-to-be-set lock bit will test the negative flag just like the x86 implementation. This should be more efficient than the generic implementation in filemap.c. It would be better if m68k had __GCC_ASM_FLAG_OUTPUTS__. Coldfire doesn't have a byte-sized EOR, so we test bit 7 after the EOR, which is a second memory access, but it's slightly better than the current C code.

fbdev: Replace fb_pgprotect() with pgprot_framebuffer()
Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer(). The helper sets VMA page-access flags for framebuffers in device I/O memory. Also clean up the helper's parameters and return value. Instead of the VMA instance, pass the individial parameters separately: existing page-access flags, the VMAs start and end addresses and the offset in the underlying device memory rsp file. Return the new page-access flags. These changes align pgprot_framebuffer() with other pgprot_() functions. v4: * fix commit message (Christophe) v3: * rename fb_pgprotect() to pgprot_framebuffer() (Arnd) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> # m68k Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230922080636.26762-3-tzimmermann@suse.de |
