block: switch polling to be bio based
Replace the blk_poll interface that requires the caller to keep a queue and cookie from the submissions with polling based on the bio. Polling for the bio itself leads to a few advantages: - the cookie construction can made entirely private in blk-mq.c - the caller does not need to remember the request_queue and cookie separately and thus sidesteps their lifetime issues - keeping the device and the cookie inside the bio allows to trivially support polling BIOs remapping by stacking drivers - a lot of code to propagate the cookie back up the submission path can be removed entirely.

ARM: SoC fixes for 5.15, part 2
A small number fixes this time, mostly touching actual code:
- Add platform device for i.MX System Reset Controller (SRC) to fix
a regression caused by fw_devlink change.
- A fixup for a boot regression caused by my own rework for the
Qualcomm SCM driver.
- Multiple bugfixes for the Arm FFA and optee firmware drivers,
addressing problems when they are built as a loadable module.
- Four dts bugfixes for the Broadcom SoC used in Raspberry pi, addressing
VEC (video encoder), MDIO bus controller #address-cells/#size-cells,
SDIO voltage and PCIe host bridge dtc warnings.

x86/fpu: Mask out the invalid MXCSR bits properly
This is a fix for the fix (yeah, /facepalm).
The correct mask to use is not the negation of the MXCSR_MASK but the
actual mask which contains the supported bits in the MXCSR register.

csky: Fixup regs.sr broken in ptrace
gpr_get() return the entire pt_regs (include sr) to userspace, if we don't restore the C bit in gpr_set, it may break the ALU result in that context. So the C flag bit is part of gpr context, that's why riscv totally remove the C bit in the ISA. That makes sr reg clear from userspace to supervisor privilege.

csky: don't let sigreturn play with priveleged bits of status register
csky restore_sigcontext() blindly overwrites regs->sr with the value it finds in sigcontext. Attacker can store whatever they want in there, which includes things like S-bit. Userland shouldn't be able to set that, or anything other than C flag (bit 0). Do the same thing other architectures with protected bits in flags register do - preserve everything that shouldn't be settable in user mode, picking the rest from the value saved is sigcontext.

KVM: PPC: Book3S HV: Make idle_kvm_start_guest() return 0 if it went to guest
We call idle_kvm_start_guest() from power7_offline() if the thread has
been requested to enter KVM. We pass it the SRR1 value that was returned
from power7_idle_insn() which tells us what sort of wakeup we're
processing.
Depending on the SRR1 value we pass in, the KVM code might enter the
guest, or it might return to us to do some host action if the wakeup
requires it.
If idle_kvm_start_guest() is able to handle the wakeup, and enter the
guest it is supposed to indicate that by returning a zero SRR1 value to
us.
That was the behaviour prior to commit 10d91611f426 ("powerpc/64s:
Reimplement book3s idle code in C"), however in that commit the
handling of SRR1 was reworked, and the zeroing behaviour was lost.
Returning from idle_kvm_start_guest() without zeroing the SRR1 value can
confuse the host offline code, causing the guest to crash and other
weirdness.

KVM: PPC: Book3S HV: Fix stack handling in idle_kvm_start_guest()
In commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in
C") kvm_start_guest() became idle_kvm_start_guest(). The old code
allocated a stack frame on the emergency stack, but didn't use the
frame to store anything, and also didn't store anything in its caller's
frame.
idle_kvm_start_guest() on the other hand is written more like a normal C
function, it creates a frame on entry, and also stores CR/LR into its
callers frame (per the ABI). The problem is that there is no caller
frame on the emergency stack.
The emergency stack for a given CPU is allocated with:
paca_ptrs[i]->emergency_sp = alloc_stack(limit, i) + THREAD_SIZE;
So emergency_sp actually points to the first address above the emergency
stack allocation for a given CPU, we must not store above it without
first decrementing it to create a frame. This is different to the
regular kernel stack, paca->kstack, which is initialised to point at an
initial frame that is ready to use.
idle_kvm_start_guest() stores the backchain, CR and LR all of which
write outside the allocation for the emergency stack. It then creates a
stack frame and saves the non-volatile registers. Unfortunately the
frame it creates is not large enough to fit the non-volatiles, and so
the saving of the non-volatile registers also writes outside the
emergency stack allocation.
The end result is that we corrupt whatever is at 0-24 bytes, and 112-248
bytes above the emergency stack allocation.
In practice this has gone unnoticed because the memory immediately above
the emergency stack happens to be used for other stack allocations,
either another CPUs mc_emergency_sp or an IRQ stack. See the order of
calls to irqstack_early_init() and emergency_stack_init().
The low addresses of another stack are the top of that stack, and so are
only used if that stack is under extreme pressue, which essentially
never happens in practice - and if it did there's a high likelyhood we'd
crash due to that stack overflowing.
Still, we shouldn't be corrupting someone else's stack, and it is purely
luck that we aren't corrupting something else.
To fix it we save CR/LR into the caller's frame using the existing r1 on
entry, we then create a SWITCH_FRAME_SIZE frame (which has space for
pt_regs) on the emergency stack with the backchain pointing to the
existing stack, and then finally we switch to the new frame on the
emergency stack.

Starting with commit 6b2117ad65f1 ("of: property: fw_devlink: Add
support for "resets" and "pwms""), the imx-drm driver fails to load
due to forever dormant devlinks to the reset-controller node. This
node was never associated with a struct device.
Add a platform device to allow fw_devnode to activate the devlinks.

powerpc/xive: Discard disabled interrupts in get_irqchip_state()
When an interrupt is passed through, the KVM XIVE device calls the
set_vcpu_affinity() handler which raises the P bit to mask the
interrupt and to catch any in-flight interrupts while routing the
interrupt to the guest.
On the guest side, drivers (like some Intels) can request at probe
time some MSIs and call synchronize_irq() to check that there are no
in flight interrupts. This will call the XIVE get_irqchip_state()
handler which will always return true as the interrupt P bit has been
set on the host side and lock the CPU in an infinite loop.
Fix that by discarding disabled interrupts in get_irqchip_state().
Fixes: da15c03b047d ("powerpc/xive: Implement get_irqchip_state method for XIVE to fix shutdown race")

ARM: dts: bcm2711-rpi-4-b: Fix usb's unit address
The unit address is supposed to represent '<device>,<function>'. Which are both 0 for RPi4b's XHCI controller. On top of that although OpenFirmware states bus number goes in the high part of the last reg parameter, FDT doesn't seem to care for it[1], so remove it.

ARM: dts: bcm2711-rpi-4-b: Fix pcie0's unit address formatting
dtbs_check currently complains that:
arch/arm/boot/dts/bcm2711-rpi-4-b.dts:220.10-231.4: Warning
(pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format
error, expected "0,0"
Unsurprisingly pci@0,0 is the right address, as illustrated by its reg
property:
&pcie0 {
pci@0,0 {
/*
* As defined in the IEEE Std 1275-1994 document,
* reg is a five-cell address encoded as (phys.hi
* phys.mid phys.lo size.hi size.lo). phys.hi
* should contain the device's BDF as 0b00000000
* bbbbbbbb dddddfff 00000000. The other cells
* should be zero.
*/
reg = <0 0 0 0 0>;
};
};
The device is clearly 0. So fix it.
Also add a missing 'device_type = "pci"'.

arm64/hugetlb: fix CMA gigantic page order for non-4K PAGE_SIZE
For non-4K PAGE_SIZE configs, the largest gigantic huge page size is
CONT_PMD_SHIFT order. On arm64 with 64K PAGE_SIZE, the gigantic page is
16G. Therefore, one should be able to specify 'hugetlb_cma=16G' on the
kernel command line so that one gigantic page can be allocated from CMA.
However, when adding such an option the following message is produced:
hugetlb_cma: cma area should be at least 8796093022208 MiB
This is because the calculation for non-4K gigantic page order is
incorrect in the arm64 specific routine arm64_hugetlb_cma_reserve().

x86/Kconfig: Do not enable AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT automatically
This Kconfig option was added initially so that memory encryption is
enabled by default on machines which support it.
However, devices which have DMA masks that are less than the bit
position of the encryption bit, aka C-bit, require the use of an IOMMU
or the use of SWIOTLB.
If the IOMMU is disabled or in passthrough mode, the kernel would switch
to SWIOTLB bounce-buffering for those transfers.
In order to avoid that,
2cc13bb4f59f ("iommu: Disable passthrough mode when SME is active")
disables the default IOMMU passthrough mode so that devices for which the
default 256K DMA is insufficient, can use the IOMMU instead.
However 2, there are cases where the IOMMU is disabled in the BIOS, etc.
(think the usual hardware folk "oops, I dropped the ball there" cases) or a
driver doesn't properly use the DMA APIs or a device has a firmware or
hardware bug, e.g.:
ea68573d408f ("drm/amdgpu: Fail to load on RAVEN if SME is active")
However 3, in the above GPU use case, there are APIs like Vulkan and
some OpenGL/OpenCL extensions which are under the assumption that
user-allocated memory can be passed in to the kernel driver and both the
GPU and CPU can do coherent and concurrent access to the same memory.
That cannot work with SWIOTLB bounce buffers, of course.
So, in order for those devices to function, drop the "default y" for the
SME by default active option so that users who want to have SME enabled,
will need to either enable it in their config or use "mem_encrypt=on" on
the kernel command line.

powerpc fixes for 5.15 #3
Fix a regression hit by the IPR SCSI driver, introduced by the recent addition of MSI
domains on pseries.
A big series including 8 BPF fixes, some with potential security impact and the rest
various code generation issues.
Fix our program check assembler entry path, which was accidentally jumping into a gas
macro and generating strange stack frames, which could confuse find_bug().
A couple of fixes, and related changes, to fix corner cases in our machine check handling.
Fix our DMA IOMMU ops, which were not always returning the optimal DMA mask, leading to
at least one device falling back to 32-bit DMA when it shouldn't.
A fix for KUAP handling on 32-bit Book3S.
Fix crashes seen when kdumping on some pseries systems.

asm-generic: build fixes for v5.15
There is one build fix for Arm platforms that ended up impacting most architectures because of the way the drivers/firmware Kconfig file is wired up: The CONFIG_QCOM_SCM dependency have caused a number of randconfig regressions over time, and some still remain in v5.15-rc4. The fix we agreed on in the end is to make this symbol selected by any driver using it, and then building it even for non-Arm platforms with CONFIG_COMPILE_TEST. To make this work on all architectures, the drivers/firmware/Kconfig file needs to be included for all architectures to make the symbol itself visible. In a separate discussion, we found that a sound driver patch that is pending for v5.16 needs the same change to include this Kconfig file, so the easiest solution seems to have my Kconfig rework included in v5.15. There is a small merge conflict against an earlier partial fix for the QCOM_SCM dependency problems. Finally, the branch also includes a small unrelated build fix for NOMMU architectures.

ARM: dts: spear3xx: Fix gmac node
On SPEAr3xx, ethernet driver is not compatible with the SPEAr600 one. Indeed, SPEAr3xx uses an earlier version of this IP (v3.40) and needs some driver tuning compare to SPEAr600. The v3.40 IP support was added to stmmac driver and this patch fixes this issue and use the correct compatible string for SPEAr3xx Signed-off-by: Herve Codina <herve.codina@bootlin.com> Signed-off-by: David S.

ARM: SoC fixes for v5.15
This is a larger than normal update for Arm SoC specific code, most
of it in device trees, but also drivers and the omap and at91/sama7
platforms:
- There are four new entries to the MAINTAINERS file: Sven Peter and
Alyssa Rosenzweig for Apple M1, Romain Perier for Mstar/sigmastar,
and Vignesh Raghavendra for TI K3
- Build fixes to address randconfig warnings in sharpsl, dove, omap1,
and qcom platforms as well as the scmi and op-tee subsystems
- Regression fixes for missing CONFIG_FB and other options for several
defconfigs
- Several bug fixes for the newly added Microchip SAMA7 platform,
mostly regarding power management
- Missing SMP barriers to protect accesses to SCMI virtio device
- Regression fixes for TI OMAP, including a boot-time hang on am335x.
- Lots of bug fixes for NXP i.MX, mostly addressing incorrect settings
in devicetree files, and one revert for broken suspend.
- Fixes for ARM Juno/Vexpress devicetree files, addressing a couple
of schema warnings.
- Regression fixes for qualcomm SoC specific drivers and devicetree
files, reverting an mdt_loader change and at least pastially
reverting some of the 5.15 DTS changes, plus some minor bugfixes

firmware: include drivers/firmware/Kconfig unconditionally
Compile-testing drivers that require access to a firmware layer fails when that firmware symbol is unavailable. This happened twice this week: - My proposed to change to rework the QCOM_SCM firmware symbol broke on ppc64 and others. - The cs_dsp firmware patch added device specific firmware loader into drivers/firmware, which broke on the same set of architectures. We should probably do the same thing for other subsystems as well, but fix this one first as this is a dependency for other patches getting merged.

pseries/eeh: Fix the kdump kernel crash during eeh_pseries_init
On pseries LPAR when an empty slot is assigned to partition OR in single LPAR mode, kdump kernel crashes during issuing PHB reset. In the kdump scenario, we traverse all PHBs and issue reset using the pe_config_addr of the first child device present under each PHB. However the code assumes that none of the PHB slots can be empty and uses list_first_entry() to get the first child device under the PHB. Since list_first_entry() expects the list to be non-empty, it returns an invalid pci_dn entry and ends up accessing NULL phb pointer under pci_dn->phb causing kdump kernel crash. This patch fixes the below kdump kernel crash by skipping empty slots: audit: initializing netlink subsys (disabled) thermal_sys: Registered thermal governor 'fair_share' thermal_sys: Registered thermal governor 'step_wise' cpuidle: using governor menu pstore: Registered nvram as persistent store backend Issue PHB reset ... audit: type=2000 audit(1631267818.000:1): state=initialized audit_enabled=0 res=1 BUG: Kernel NULL pointer dereference on read at 0x00000268 Faulting instruction address: 0xc000000008101fb0 Oops: Kernel access of bad area, sig: 7 [#1] LE PAGE_SIZE=64K MMU=Radix SMP NR_CPUS=2048 NUMA pSeries Modules linked in: CPU: 7 PID: 1 Comm: swapper/7 Not tainted 5.14.0 #1 NIP: c000000008101fb0 LR: c000000009284ccc CTR: c000000008029d70 REGS: c00000001161b840 TRAP: 0300 Not tainted (5.14.0) MSR: 8000000002009033 <SF,VEC,EE,ME,IR,DR,RI,LE> CR: 28000224 XER: 20040002 CFAR: c000000008101f0c DAR: 0000000000000268 DSISR: 00080000 IRQMASK: 0 ...

powerpc/32s: Fix kuap_kernel_restore()
At interrupt exit, kuap_kernel_restore() calls kuap_unlock() with the
value contained in regs->kuap. However, when regs->kuap contains
0xffffffff it means that KUAP was not unlocked so calling kuap_unlock()
is unrelevant and results in jeopardising the contents of kernel space
segment registers.
So check that regs->kuap doesn't contain KUAP_NONE before calling
kuap_unlock(). In the meantime it also means that if KUAP has not
been correcly locked back at interrupt exit, it must be locked
before continuing. This is done by checking the content of
current->thread.kuap which was returned by kuap_get_and_assert_locked()
