[PATCH 0/2] KVM: PPC: e500: Fix build error due to crappy KVM code

Posted by Sean Christopherson 1 month ago

Fix an e500 build error that was introduced by the recent kmalloc_obj()
conversion, but in reality is due to crappy KVM code that has existed for
~13 years.

I'm taking this through kvm-x86 fixes, because it's breaking my testing setup,
and obviously no one cares about KVM e500 since PPC_WERROR is default 'y' and
needs to be explicitly disabled via PPC_DISABLE_WERROR.

Applied to kvm-x86 fixes, thanks!
