target-i386/cpu.c:ext_save_area uses magic numbers for the xsave
area offets and sizes, and target-i386/kvm.c:kvm_{put,get}_xsave()
uses offset macros and bit manipulation to access the xsave area.
This series changes both to use C structs for those operations.
I still need to figure out a way to write unit tests for the new
code. Maybe I will just copy and paste the new and old functions,
and test them locally (checking if they give the same results
when translating blobs of random bytes).
Changes v1 -> v2:
* Use uint8_t[8*n] instead of uint64_t[n] for register data
* Keep the QEMU_BUILD_BUG_ON lines
Changes v2 -> v3:
* XMM_Q helper is now ZMM_Q
* Added PKRU state
Eduardo Habkost (3):
target-i386: Define structs for layout of xsave area
target-i386: Use xsave structs for ext_save_area
target-i386: kvm: Use X86XSaveArea struct for xsave save/load
