The patch titled
probe_kernel_address() needs to do set_fs()
has been removed from the -mm tree. Its filename was
probe_kernel_address-needs-to-do-set_fs.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: probe_kernel_address() needs to do set_fs()
From: Andrew Morton <akpm@xxxxxxxx>
probe_kernel_address() purports to be generic, only it forgot to select
KERNEL_DS, so it presently won't work right on all architectures.
Signed-off-by: Andrew Morton <akpm@xxxxxxxx>
