KVM: arm64: Reset PMC_EL0 to avoid a panic() on systems with no PMU
The above is causing the following build error for ARM64 ...
arch/arm64/kvm/sys_regs.c: In function ‘reset_pmcr’:
arch/arm64/kvm/sys_regs.c:624:3: error: implicit declaration of function ‘vcpu_sys_reg’ [-Werror=implicit-function-declaration]
vcpu_sys_reg(vcpu, PMCR_EL0) = 0;
^~~~~~~~~~~~
arch/arm64/kvm/sys_regs.c:624:32: error: lvalue required as left operand of assignment
vcpu_sys_reg(vcpu, PMCR_EL0) = 0;
Is this also broken in Linus's tree?
No, Linus' tree is not broken. However, I don't see this change in Linus'
tree (v5.17-rc8).
Ah, this is a "fix something broken in stable-only" type patch :(
James, I'm dropping this from the 4.19, 4.9, and 4.14 trees right now as
it looks broken :(
What would you prefer I do here:
1 post a revert for the original problematic backport.
2 post versions of this to fix each of the above 3 stable kernels. (instead of putting conditions in the stable tag).
Thanks,
James
