X-Git-Tag: v5.8-rc1~21^2~53
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=00cf8baf9c2af3c17f9d77bb9d07d44d330d0df2;p=thirdparty%2Fkernel%2Flinux.git

x86/entry/64: Simplify idtentry_body

All C functions which do not have an error code have been converted to the
new IDTENTRY interface which does not expect an error code in the
arguments. Spare the XORL.
