[PATCH 3/3] ARM64: perf: add support for frame pointer unwinding in compat mode

by jean.pihet＠linaro.org

From: Jean Pihet <jean.pihet(a)linaro.org> When profiling a 32-bit application, user space callchain unwinding using the frame pointer is performed in compat mode. The code is taken over from the AARCH32 code and adapted to work on AARCH64.

[PATCH RESEND] arm64: KVM: Add Kconfig option for max VCPUs per-Guest

by Anup Patel

Current max VCPUs per-Guest is set to 4 which is preventing us from creating a Guest (or VM) with 8 VCPUs on Host (e.g. X-Gene Storm SOC) with 8 Host CPUs. The correct value of max VCPUs per-Guest should be same as the max CPUs supported by GICv2 which is 8 but, increasing value of max VCPUs per-Guest can make things slower hence we add Kconfig option to let KVM users select appropriate max VCPUs per-Guest.
