Subject: [GIT PULL] x86/asm changes for v5.6
Date: Tue, 28 Jan 2020 17:59:06 +0100	[thread overview]
Message-ID: <20200128165906.GA67781@gmail.com> (raw)

Linus,

Please pull the latest x86-asm-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-asm-for-linus

   # HEAD: 183ef7adf4ed638ac0fb0c3c9a71fc00e8512b61 x86/boot: Simplify calculation of output address

Misc updates: 

 - Remove last remaining calls to exception_enter/exception_exit() and 
   simplify the entry code some more.

 - Remove force_iret()

 - Add support for "Fast Short Rep Mov", which is available starting with 
   Ice Lake Intel CPUs - and make the x86 assembly version of memmove() 
   use REP MOV for all sizes when FSRM is available.

 - Micro-optimize/simplify the 32-bit boot code a bit.

 - Use a more future-proof SYSRET instruction mnemonic

 Thanks,

	Ingo
