Re: [Xen-devel] Error booting Xen

[Harmandeep Kaur <write.harmandeep@xxxxxxxxx>]

I tried to apply your patches but it seems
to have some merge conflicts with latest
staging branch.

~/xen$ git apply ~/Downloads/x86-xsaves-init.patch
error: patch failed: xen/arch/x86/hvm/hvm.c:2094
error: xen/arch/x86/hvm/hvm.c: patch does not apply

Do you mind having a look ?

Regards,
Harmandeep
