- Remove a superfluous noinline which prevents GCC-7.3 to optimize a stub
function away.
- Allow uprobes on REP NOP and do not treat them like word-sized branch
instructions.
- Make the VDSO symbol export of __vdso_sgx_enter_enclave() depend on
CONFIG_X86_SGX to prevent build fails with newer LLVM versions which
rightfully detect that there is no function behind the symbol.

Pull x86 fixes from Thomas Gleixner:
"Three small x86 fixes which did not make it into 6.1:
- Remove a superfluous noinline which prevents GCC-7.3 to optimize a
stub function away
- Allow uprobes on REP NOP and do not treat them like word-sized
branch instructions
- Make the VDSO symbol export of __vdso_sgx_enter_enclave() depend on
CONFIG_X86_SGX to prevent build failures with newer LLVM versions
which rightfully detect that there is no function behind the
symbol"
* tag 'x86-urgent-2022-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/vdso: Conditionally export __vdso_sgx_enter_enclave()
uprobes/x86: Allow to probe a NOP instruction with 0x66 prefix
x86/alternative: Remove noinline from __ibt_endbr_seal[_end]() stubs

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
