Subject[GIT PULL] x86/asm changes for v5.6
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
