[PATCH 0/2] timers test fix and duplicate defines cleanup

by Shuah Khan

The first patch in this two patch fixes warn_unused_result compile time warning in posix_timers test. The second patch removes local NSEC_PER_SEC and USEC_PER_SEC defines. NSEC_PER_SEC and USEC_PER_SEC are defines in several timers tests. These defines are inconsistent with variations of ULL, LL, etc. without any explanation why it is necessary. These defines can be picked up from include/vdso/time64.h header file. In the interest of making it easier to maintain, remove the local defines. Include include/vdso/time64.h instead. This change will also make the defines consistent.

[PATCH net] selftests/net: packetdrill: increase timing tolerance in debug mode

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Some packetdrill tests are flaky in debug mode. As discussed, increase tolerance. We have been doing this for debug builds outside ksft too. Previous setting was 10000. A manual 50 runs in virtme-ng showed two failures that needed 12000. To be on the safe side, Increase to 14000.

[RFC PATCH v1 0/2] Allow the RAS feature bit in ID_AA64PFR0_EL1 writable from userspace

by Shaoqin Huang

Currently the RAS feature bit is not writable in ID_AA64PFR0EL1, this makes migration fail when migration from the machine which RAS is 1 to another machine which RAS is 2. Allow RAS writable from userspace would make the migration possible between two machines which RAS is different.

[PATCH AUTOSEL 6.6 071/139] selftests/nolibc: avoid passing NULL to printf("%s")

by Sasha Levin

From: Thomas Weißschuh <linux(a)weissschuh.net> [ Upstream commit f1a58f61d88642ae1e6e97e9d72d73bc70a93cb8 ] Clang on higher optimization levels detects that NULL is passed to printf("%s") and warns about it.
