[PATCH v2 7/9] ARC: use fixed frequencies in arc_set_early_base_baud()

From: Alexey Brodkin UARTs usually have fixed clock so we're switching to use of constant values instead of something derived from core clock frequency. Among other things this will allow us to get rid of arc_{get|set}_core_freq() and switch to generic clock framework

[PATCH v2 5/9] ARC: clockevent: DT based probe

[PATCH v2 3/9] ARC: clockevent: switch to cpu notifier for clockevent setup

From: Noam Camus ARC Timers so far have been handled as "legacy" w/o explicit description in DT. This poses challenge for newer platforms wanting to use them. This series will eventually help move timers over to DT. This patch does a small change of using a CPU notifier to set

[PATCH 2/2] KVM: MMU: fix reserved bit check for pte.u=0/pte.w=0/CR0.WP=0/CR4.SMEP=1/EFER.NX=0

KVM handles supervisor writes of a pte.u=0/pte.w=0/CR0.WP=0 page by setting U=0 and W=1 in the shadow PTE. This will cause a user write to fault and a supervisor write to succeed (which is correct because CR0.WP=0). A user read instead will flip U=0 to 1 and W=1 back to 0. This enables user
