The kvm code was refactored to convert some of kvm assembly routines to C.
This includes commits which moved code path for the kvm guest entry/exit
for p7/8 from aseembly to C. As part of the code changes, usage of some of
the macros were removed. But definitions still exist in the assembly files.
Commits are listed below:
Commit 2e1ae9cd56f8 ("KVM: PPC: Book3S HV: Implement radix prefetch workaround by disabling MMU")
Commit 9769a7fd79b6 ("KVM: PPC: Book3S HV: Remove radix guest support from P7/8 path")
Commit fae5c9f3664b ("KVM: PPC: Book3S HV: remove ISA v3.0 and v3.1 support from P7/8 path")
Commit 57dc0eed73ca ("KVM: PPC: Book3S HV P9: Implement PMU save/restore in C")
Many of the asm-offset macro definitions were missed to remove. This patchset
fixes by removing the unused macro definitions.
Patch1 removes a set of unused kvm vcpu and hstate macros from the
asm-offset.c
Patch2 removes unused host_mmcr references for MMCR3/SIER2/SIER3
Changelog:
v1 -> v2:
Merge all the macro removal part from asm-offset.c file into a single patch
as suggested by Christophe Leroy.
