Subject: [GIT PULL] x86/entry changes for v6.7
Date: Sat, 28 Oct 2023 15:37:46 +0200 [thread overview]
Message-ID: <ZT0OqhIh/7c9IOYU@gmail.com> (raw)
Linus,

# HEAD: 1a09a27153f91cd7676b2d4ca574577572a8c999 x86/entry/32: Clean up syscall fast exit tests
Changes to the x86 entry code in v6.7:
- Make IA32_EMULATION boot time configurable with
the new ia32_emulation=<bool> boot option.
- Clean up fast syscall return validation code: convert
it to C and refactor the code.
- As part of this, optimize the canonical RIP test code.
Thanks,
Ingo
