2014-12-06x86, microcode: Reload microcode on resumeBorislav Petkov7-16/+84
Normally, we do reapply microcode on resume. However, in the cases where that microcode comes from the early loader and the late loader hasn't been utilized yet, there's no easy way for us to go and apply the patch applied during boot by the early loader. Thus, reuse the patch stashed by the early loader for the BSP. Signed-off-by: Borislav Petkov <[email protected]>
2014-12-06x86, microcode: Don't initialize microcode code on paravirtBoris Ostrovsky1-1/+1
Paravirtual guests are not expected to load microcode into processors and therefore it is not necessary to initialize microcode loading logic. In fact, under certain circumstances initializing this logic may cause the guest to crash. Specifically, 32-bit kernels use __pa_nodebug() macro which does not work in Xen (the code path that leads to this macro happens during resume when we call mc_bp_resume()->load_ucode_ap() ->check_loader_disabled_ap()) Signed-off-by: Boris Ostrovsky <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Borislav Petkov <[email protected]>

2014-12-05ARM: dts: rk3288: add arm,cpu-registers-not-fw-configuredSonny Rao1-0/+1
This will enable use of physical arch timers on rk3288, where each core comes out of reset with a different virtual offset. Using physical timers will help with SMP booting on coreboot and older u-boot and should also allow suspend-resume and cpu-hotplug to work on all firmwares. Firmware which does initialize the cpu registers properly at boot and cpu-hotplug can remove this property from the device tree.

2014-12-05mmc: queue: Improve error handling during allocation of bounce buffersBhuvanesh Surachari1-7/+9
Allocation of previous bounce buffer in mmc_init_queue when the current bounce buffer allocation fails was leading to a crash later in __blk_segment_map_sg. Error handling is improved by allocating previous bounce buffer only if the current bounce buffer allocation succeeds.
