Hi Greg, Could you please revert 7212e37cbdf9 x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls from 4.4-stable? In 4.4-stable efi_runtime_lock as defined in drivers/firmware/efi/runtime-wrappers.c is a spinlock (given it predates commit dce48e351c0d) and commit f331e766c4be x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls which 7212e37cbdf9 is a backport of, needs it to be a semaphore. Cheers, Hedi. -- Be careful of reading health books, you might die of a misprint. -- Mark Twain
