[PATCH v8 00/11] KVM Guest Debug support for arm64

[alex.bennee@linaro.org (Alex Bennée)]

Here is V8 of the KVM Guest Debug support for arm64.

The diffstat between v7 and v8 is getting pretty small and as I
haven't re-based you can run:

        git diff -u guest-debug/4.1-v7..guest-debug/4.1-v8

And the kernelci report is at:

        http://kernelci.org/build/alex/kernel/v4.1-11-g182a5fa64600/


The only real changes apart from comments and white space are to
sys_regs which sees another minor re-factoring. The 32 bit handling
explicitly preserves the top 32 bits of the AArch64 registers although
I'm not convinced it matter too much as for a booting AArch32 guest
kernel they should start as 0 and never change.

For full details see the changelog on each of the patches.
