Hi Al,
Today's linux-next merge of the signal tree got a conflict in
arch/x86/kernel/process_32.c between commit 304bceda6a18 ("x86, fpu: use
non-lazy fpu restore for processors supporting xsave") from the tip tree
and commits 450ca1f882ab ("x86: get rid of TIF_IRET hackery") and
5daca7153d68 ("x86, um/x86: switch to generic sys_execve and
kernel_execve") from the signal tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
