Linus Torvalds a5ed1e96ca powerpc fixes for 5.1 #3
One fix for a boot failure on 32-bit, introduced during the merge window.
 
 A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall
 clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and
 backward.
 
 Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some
 systems it was reporting that the count cache was disabled and also that we were
 flushing the count cache on context switch. Only the former is true, and given
 that the count cache is disabled it doesn't make any sense to flush it. No one
 reported it, so presumably the presence of any mitigation is all people check
 for.
 
 Finally a small build fix for zsmalloc on 32-bit.
