commit 6583327c4dd55acbbf2a6f25e775b28b3abf9a42 upstream.
Commit d61931d89b, "x86: Add optimized popcnt variants" introduced
compile flag -fcall-saved-rdi for lib/hweight.c. When combined with
options -fprofile-arcs and -O2, this flag causes gcc to generate
broken constructor code. As a result, a 64 bit x86 kernel compiled
with CONFIG_GCOV_PROFILE_ALL=y prints message "gcov: could not create
file" and runs into sproadic BUGs during boot.
The gcc people indicate that these kinds of problems are endemic when
using ad hoc calling conventions. It is therefore best to treat any
file compiled with ad hoc calling conventions as an isolated
environment and avoid things like profiling or coverage analysis,
since those subsystems assume a "normal" calling conventions.
This patch avoids the bug by excluding lib/hweight.o from coverage
profiling.
