powerpc: Relocatable system call no longer uses the LR
We had some code to restore the LR in the relocatable system call path back when we used the LR to do an indirect branch. Commit 6a404806dfce ("powerpc: Avoid link stack corruption in MMU on syscall entry path") changed this to use the CTR which is volatile across system calls so does not need restoring. Remove the stale comment and the restore of the LR. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
