Pull x86 int80 fixes from Dave Hansen:
"Avoid VMM misuse of 'int 0x80' handling in TDX and SEV guests.
It also has the very nice side effect of getting rid of a bunch of
assembly entry code"
* tag 'x86-int80-20231207' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/tdx: Allow 32-bit emulation by default
