James Clark bb339db4d3 arm: perf: Fix ARCH=arm build with GCC ... LLVM ignores everything inside the if statement and doesn't generate errors, but GCC doesn't ignore it, resulting in the following error: drivers/perf/arm_pmuv3.c: In function ‘armv8pmu_write_evtype’: include/linux/bits.h:34:29: error: left shift count >= width of type [-Werror=shift-count-overflow] 34 | (((~UL(0)) - (UL(1) << (l)) + 1) & \ Fix it by using GENMASK_ULL which doesn't overflow on arm32 (even though the value is never used there).
