Just a y2038 fix to the pdc202xx_new IDE driver.
Please pull, thanks a lot!
The following changes since commit 6a13feb9c82803e2b815eca72fa7a9f5561d7861:
Linux 4.3 (2015-11-01 16:05:25 -0800)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide.gi
Currently, the set_memory_* functions that are implemented for arm64
are restricted to module addresses only. This was mostly done
because arm64 maps normal zone memory with larger page sizes to
improve TLB performance. This has the side effect though of making it
difficult to adjust attributes at
Rather than always putting the least restrictived permissions
(PAGE_KERNEL_EXEC) when spliting a pmd into pages, use
the existing permissions from the pmd for the page.

the Kconfig can be dropped. This has been briefly tested but not s
