linux-next: build failure after merge of the kvm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

After merging the kvm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

arch/x86/kvm/svm/svm.c: In function 'kvm_machine_check':
arch/x86/kvm/svm/svm.c:1834:2: error: too many arguments to function 'do_machine_check'
 1834 |  do_machine_check(&regs, 0);
      |  ^~~~~~~~~~~~~~~~
In file included from arch/x86/kvm/svm/svm.c:36:
arch/x86/include/asm/mce.h:254:6: note: declared here
  254 | void do_machine_check(struct pt_regs *pt_regs);
      |      ^~~~~~~~~~~~~~~~

Caused by commit

  1c164cb3ffd0 ("KVM: SVM: Use do_machine_check to pass MCE to the host")

interacting with commit

  aaa4947defff ("x86/entry: Convert Machine Check to IDTENTRY_IST")

from the tip tree.

I added the following merge fix patch.
