Hey Linus, Please git pull the following tag: git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git stable/for-linus-3.12-rc0-tag-two This pull I usually do after rc1 is out but because we have a nice amount of fixes, some bootup related fixes for ARM, and it is early in the cycle we figured to do it now to help with tracking of potential regressions. The simple ones are the ARM ones - one of the patches fell through the cracks, other fixes a bootup issue (unconditionally using Xen functions). Then a fix for a regression causing preempt count being off (patch causing this went in v3.12). Lastly are the fixes to make Xen PVHVM guests use PV ticketlocks (Xen PV already does). The enablement of that was suppose to be part of commit 816434ec4a674fcdb3c2221a6dffdc8f34020550 (Merge branch 'x86-spinlocks-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip) Pull x86 spinlock changes from Ingo Molnar: "The biggest change here are paravirtualized ticket spinlocks (PV spinlocks), which bring a nice speedup on various benchmarks. ..." but unfortunatly it would cause hang when booting Xen PVHVM guests. Yours truly got all of the bugs fixed last week and they (six of them) are included in this pull.
