Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging
acpi,pc,build bug fixes
Here are some bugfixes for 2.0.
A bugfix for acpi for pci bridges, and a build fix for
old systems without pthread_setname_np: both fix regressions
so we definitely want to include them.
HPET fix is not for a regression but looks very safe,
fixes a nasty bug and has been on list for a while.
