Revision ff66135015726696568e998720d9b6afe2d04642 authored by Marco Elver on 12 July 2019, 03:53:56 UTC, committed by Linus Torvalds on 12 July 2019, 18:05:42 UTC
This patch is a pre-requisite for enabling KASAN bitops instrumentation; using static_cpu_has instead of boot_cpu_has avoids instrumentation of test_bit inside the uaccess region. With instrumentation, the KASAN check would otherwise be flagged by objtool. For consistency, kernel/signal.c was changed to mirror this change, however, is never instrumented with KASAN (currently unsupported under x86 32bit).
