KVM_REG_MIPS_CP0_EBASE is defined as 64bit, but is a 32bit register even
in MIPS64, so fix the definition.
Note, this definition isn't actually used yet, so it didn't cause any
problems.

Contrary to the comment, the guest CP0_EPC register cannot be set via
kvm_regs, since it is distinct from the guest PC. Add the EPC register
to the KVM_{GET,SET}_ONE_REG ioctl interface.

We are currently running with timer frequencies of over 2GHz, so the
width of this variable is close to the limit.
Interesting. Do you have 64-bit Count/Compare

So far this was tested with host running KVM using MIPS-VZ (on Cavium
Octeon3). A paravirtualized mips kernel was used for the guest.

Maybe it makes sense to put this patch before the main mips one so that
the function doesn't have to be added for mips in the first place

These patches contain changes that I am currently using on top of

The core is David's work for mips support and loading elf binaries.

Minor thing I didn't spot with v1 (sorry).
I think this patch should probably be moved before patch 6 with the mips
part squashed

CVMSEG is related to the CPU core not the SoC system. So needs to be
