Merge tag 'x86-build-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 build updates from Thomas Gleixner:
"Updates for KCOV instrumentation on x86:
- Prevent spurious KCOV coverage in common_interrupt()
- Fixup the KCOV Makefile directive which got stale due to a source
file rename
- Exclude stack unwinding from KCOV as it creates large amounts of
uninteresting coverage
- Provide a self test to validate that KCOV coverage of the interrupt
handling code starts not before preempt count got updated"
* tag 'x86-build-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Ignore stack unwinding in KCOV
module: Fix KCOV-ignored file name
kcov: Add interrupt handling self test
x86/entry: Remove unwanted instrumentation in common_interrupt()
