For reading and writing register values from the kernel for KVM,
we need to provide accessor functions which are guaranteed to succeed
and don't impose access checks, mask out unwritable bits, etc.
Define new fields raw_readfn and raw_writefn for this purpose;
these only need to be provided if
This patch series overhauls how we handle ARM coprocessor registers,
so that we use a consistent approach for migration, reset and
QEMU-KVM synchronisation, driven by the kernel's list of supported
registers.
The basic principle here is that we trust the kernel's list of what
registers it knows
Relax the is this a valid ARMCPRegInfo type value? check to permit
special cpregs to have flags other than ARM_CP_SPECIAL set. At
the moment none of the other flags are relevant for special regs,
but the migration related flag we're about to introduce can apply
here too.

Convert the TCG ARM target to using an (index,value) list for migrating
coprocessors. The primary benefit of the (index,value) list is for
passing state between KVM and QEMU, but it works for TCG-to-TCG
migration as well and is a useful self-contained first step.

Mark up coprocessor register definitions to add raw access
functions or mark the register as non-migratable where necessary.
