| Series | x86: remove memory constraint from "mov" instruction | expand |
+cc Paolo, Radim and Marc (to avoid saying the same thing twice) I recommend having Paolo and Radim in the To: field when sending patches for KVM or kvm-unit-tests, simply cc'ing the KVM list may not be enough to ensure Paolo/Radim sees the patch. https://lkml.kernel.org/r/0d59375c-9313-d31a-4af9-d68115e05d55@redhat.com On Thu, Sep 12, 2019 at 01:59:44PM -0700, Bill Wendling wrote: > Remove a bogus memory constraint as x86 does not have a generic > memory-to-memory "mov" instruction. > > Signed-off-by: Bill Wendling <morbo@google.com> For the actual patch: Reviewed-by: Sean Christopherson <sean.j.christopherson@intel.com> > --- > lib/x86/desc.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/lib/x86/desc.c b/lib/x86/desc.c > index 5f37cef..451f504 100644 > --- a/lib/x86/desc.c > +++ b/lib/x86/desc.c > @@ -263,7 +263,7 @@ unsigned exception_error_code(void) > { > unsigned short error_code; > > - asm("mov %%gs:6, %0" : "=rm"(error_code)); > + asm("mov %%gs:6, %0" : "=r"(error_code)); > return error_code; > } > > -- > 2.23.0.237.gc6a4ce50a0-goog >

Remove a bogus memory constraint as x86 does not have a generic memory-to-memory "mov" instruction. Signed-off-by: Bill Wendling <morbo@google.com> --- lib/x86/desc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
