[PATCH AUTOSEL 4.20 25/72] selftests: cpu-hotplug: fix case where CPUs offline > CPUs present

by Sasha Levin

From: Colin Ian King <colin.king(a)canonical.com> [ Upstream commit 2b531b6137834a55857a337ac17510d6436b6fbb ] The cpu-hotplug test assumes that we can offline the maximum CPU as described by /sys/devices/system/cpu/offline. However, in the case where the number of CPUs exceeds like kernel configuration then the offline count can be greater than the present count and we end up trying to test the offlining of a CPU that is not available to offline. Fix this by testing the maximum present CPU instead. Also, the test currently offlines the CPU and does not online it, so fix this by onlining the CPU after the test.

[PATCH] tools/selftest/vm: allow choosing mem size and page size in map_hugetlb

by Christophe Leroy

map_hugetlb maps 256Mbytes of memory with default hugepage size. This patch allows the user to pass the size and page shift as an argument in order to use different size and page size.

[PATCH] powerpc/selftest: fix type of mftb() in null_syscall

by Christophe Leroy

All callers of mftb() expect 'unsigned long', and the function itself only returns lower part of the TB so it really is 'unsigned long' not 'unsigned long long' Signed-off-by: Christophe Leroy <christophe.leroy(a)c-s.fr> --- tools/testing/selftests/powerpc/benchmarks/null_syscall.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/powerpc/benchmarks/null_syscall.c b/tools/testing/selftests/powerpc/benchmarks/null_syscall.c index ecc14d68e101..908de689a902 100644 --- a/tools/testing/selftests/powerpc/benchmarks/null_syscall.c +++ b/tools/testing/selftests/powerpc/benchmarks/null_syscall.c @@ -25,7 +25,7 @@ unsigned long long clock_frequency; unsigned long long timebase_frequency; double timebase_multiplier; -static inline unsigned long long mftb(void) +static inline unsigned long mftb(void) { unsigned long low; -- 2.13.3
