Hi,

Here is updated patches to address KVM host support in big endian ARM V7/V8.

Changes since previous version [1] and [2]:

x) joined both v7 [1] and v8 [2] series into one

Quoted 8 lines
Quoted 6 lines

x) addressed, nearly all, Christoffer's comments to previous patch series

x) Fixed few issues in 'ARM: KVM: handle 64bit values passed to mrcc or from mcrr instructions in BE case' that got discovered after moving to the latest v3.15-rc5 kernel

What were the issues?

You correctly spotted it: it related TTBR handling and access_vm_reg function

x) Fixed issue in supporting 32bit guest by V8 BE KVM host

Is this changes only from v2 to v3 or?

Thanks. Will try to do that.

Christoffer, Marc thank you very much for review! I accepted a lot of comments and update patches. For remaining issues I've sent my responses. When we get a bit more closure on remaining issues, I will report the series.

Thanks!
