The commit 78eaa10f027c ("cpuidle: powernv/pseries: Auto-promotion of
snooze to deeper idle state") introduced a timeout for the snooze idle
state so that it could be eventually be promoted to a deeper idle
state. The snooze timeout value is static and set to the target

match_string() returns the index of an array for a matching string,
which can be used instead of open coded variant.

NX can set 3rd bit in CR register for XER[SO] (Summation overflow)
which is not related to paste request. The current paste function
returns failure for the successful request when this bit is set.
So mask this bit and check the proper return status.

[ Upstream commit aa0ab02ba992eb956934b21373e0138211486ddd ]
On the 8xx, the page size is set in the PMD entry and applies to
all pages of the page table pointed by the said PMD entry.
When an app has some regular pages allocated (e.g. see below) and tries
to mmap() a huge page at a hint address
[ Upstream commit db3a528db41caaa6dfd4c64e9f5efb1c81a80467 ]
In preparation for the following patch which will fix an issue on
the 8xx by re-using the 'slices', this patch enhances the
'slices' implementation to support 32 bits CPUs.
On PPC32, the address space is limited to 4Gbytes, hence only
[ Upstream commit a3286f05bc5a5bc7fc73a9783ec89de78fcd07f8 ]
In preparation for the following patch which will enhance 'slices'
for supporting PPC32 in order to fix an issue on hugepages on 8xx,
this patch takes out of page*.h all bits related to 'slices' and put
them into newly created slice.h
[ Upstream commit 326691ad4f179e6edc7eb1271e618dd673e4736d ]
bitmap_or() and bitmap_andnot() can work properly with dst identical
to src1 or src2. There is no need of an intermediate result bitmap
that is copied back to dst in a second step.
