Pull x86 asm updates from Ingo Molnar: "The main changes in this cycle were the fsgsbase related preparatory patches from Chang S. Bae - but there's also an optimized memcpy_flushcache() and a cleanup for the __cmpxchg_double() assembly glue" * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fsgsbase/64: Clean up various details x86/segments: Introduce the 'CPUNODE' naming to better document the segment limit CPU/node NR trick x86/vdso: Initialize the CPU/node NR segment descriptor earlier x86/vdso: Introduce helper functions for CPU and node number x86/segments/64: Rename the GDT PER_CPU entry to CPU_NUMBER x86/fsgsbase/64: Factor out FS/GS segment loading from __switch_to() x86/fsgsbase/64: Convert the ELF core dump code to the new FSGSBASE helpers x86/fsgsbase/64: Make ptrace use the new FS/GS base helpers x86/fsgsbase/64: Introduce FS/GS base helper functions x86/fsgsbase/64: Fix ptrace() to read the FS/GS base accurately x86/asm: Use CC_SET()/CC_OUT() in __cmpxchg_double() x86/asm: Optimize memcpy_flushcache()
