From: Paul Gortmaker <pa...@kernel.org> Pretty much everything is documented here:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=15463 ...other than I have since put the reverts onto the v6.6/standard/base (v6.6.23-118-g2d01bc1d4eea) and ran boot tests on that for 150 iterations w/o issue. We'll still need to let the linux-stable people know there is an issue, and checking if mainline has the issue (vs. just being related to backports) remains to be determined as well. But if there is a desire to move forward, and this is blocking, well then at least there is an option. Note that I did all the testing on qemux86 w/o KVM. I figure everyone else tests qemux86-64 with KVM, right? --- Paul Gortmaker (5): Revert "x86/tdx: Allow 32-bit emulation by default" Revert "x86/entry: Do not allow external 0x80 interrupts" Revert "x86/entry: Convert INT 0x80 emulation to IDTENTRY" Revert "x86/coco: Disable 32-bit emulation by default on TDX and SEV" Revert "x86: Introduce ia32_enabled()" arch/x86/coco/tdx/tdx.c | 1 - arch/x86/entry/common.c | 97 +------------------------------- arch/x86/entry/entry_64_compat.S | 77 +++++++++++++++++++++++++ arch/x86/include/asm/ia32.h | 23 +------- arch/x86/include/asm/idtentry.h | 4 -- arch/x86/include/asm/proto.h | 4 ++ arch/x86/kernel/idt.c | 2 +- arch/x86/mm/mem_encrypt_amd.c | 11 ---- arch/x86/xen/enlighten_pv.c | 2 +- arch/x86/xen/xen-asm.S | 2 +- 10 files changed, 86 insertions(+), 137 deletions(-) -- 2.44.0
