KVM: VMX: Always inline eVMCS read/write helpers
Tag all evmcs_{read,write}() helpers __always_inline so that they can be freely used in noinstr sections, e.g. to get the VM-Exit reason in vcpu_vmx_enter_exit() (in a future patch). For consistency and to avoid more spot fixes in the future, e.g. see commit 010050a86393 ("x86/kvm: Always inline evmcs_write64()"), tag all accessors even though evmcs_read32() is the only anticipated use case in the near future. In practice, non-KASAN builds are all but guaranteed to inline the helpers anyways. vmlinux.o: warning: objtool: vmx_vcpu_enter_exit+0x107: call to evmcs_read32() leaves .noinstr.text section Reported-by: kernel test robot <[email protected]> Acked-by: Peter Zijlstra (Intel) <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
