OMAP2/3: VENC hwmod: add OCPIF_SWSUP_IDLE flag to interface
According to the hwmod interface data, the DSS submodule "VENC" uses a
clock, "dss_54m_fck"/"dss_tv_fck", which the PRCM cannot autoidle. By
default, the hwmod code assumes that interface clocks can be autoidled
by the PRCM. When the interface clock can't be autoidled by the PRCM,
those interfaces must be marked with the OCPIF_SWSUP_IDLE flag.
Otherwise, the "interface clock" will always have a non-zero use
count, and the device won't enter idle. This problem was observed on
N8x0.
Fix the immediate problem by marking the VENC interface with the
OCPIF_SWSUP_IDLE flag. But it's not clear that
"dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for
VENC. It may be that the VENC interface should use a
hardware-autoidling interface clock. This is the situation on OMAP4,
which uses "l3_div_ck" as the VENC interface clock, which can be
autoidled by the PRCM. Clarification from TI is needed.
Problem found and patch tested on N8x0 by Tony Lindgren

mm: vmscan: stop reclaim/compaction earlier due to insufficient progress if !__GFP_REPEAT
should_continue_reclaim() for reclaim/compaction allows scanning to
continue even if pages are not being reclaimed until the full list is
scanned. In terms of allocation success, this makes sense but potentially
it introduces unwanted latency for high-order allocations such as
transparent hugepages and network jumbo frames that would prefer to fail
the allocation attempt and fallback to order-0 pages. Worse, there is a
potential that the full LRU scan will clear all the young bits, distort
page aging information and potentially push pages into swap that would
have otherwise remained resident.
This patch will stop reclaim/compaction if no pages were reclaimed in the
last SWAP_CLUSTER_MAX pages that were considered. For allocations such as
hugetlbfs that use __GFP_REPEAT and have fewer fallback options, the full
LRU list may still be scanned.
Order-0 allocation should not be affected because RECLAIM_MODE_COMPACTION
is not set so the following avoids the gfp_mask being examined:
if (!(sc->reclaim_mode & RECLAIM_MODE_COMPACTION))
return false;
A tool was developed based on ftrace that tracked the latency of
high-order allocations while transparent hugepage support was enabled and
three benchmarks were run. The "fix-infinite" figures are 2.6.38-rc4 with
Johannes's patch "vmscan: fix zone shrinking exit when scan work is done"
applied.

Mean time for order-1 allocations is reduced. order-2 looks increased but
with so few allocations, it's not particularly significant. THP mean
allocation latency is also reduced. That said, allocation time varies so
significantly that the reductions are within noise.
Max allocation time is reduced by a significant amount for low-order
allocations but reduced for THP allocations which presumably are now
breaking before reclaim has done enough work.

Again, mean time for order-1 allocations is reduced while order-2

allocations is also slightly reduced albeit the reductions are within

Once again, our maximum allocation time is significantly reduced for
low-order allocations and slightly increased for THP allocations.

This benchmark creates one thread per CPU which references an amount of
anonymous memory 1.5 times the size of physical RAM. This pounds swap
quite heavily and is intended to exercise THP a bit.
Mean allocation time for order-1 is reduced as before. It's also reduced
for THP allocations but the variations here are pretty massive due to
swap. As before, maximum allocation times are significantly reduced.
Overall, the patch reduces the mean and maximum allocation latencies for
the smaller high-order allocations. This was with Slab configured so it
would be expected to be more significant with Slub which uses these size
allocations more aggressively.
The mean allocation times for THP allocations are also slightly reduced.
The maximum latency was slightly increased as predicted by the comments
due to reclaim/compaction breaking early. However, workloads care more
about the latency of lower-order allocations than THP so it's an
acceptable trade-off.

drivers/nfc/pn544.c: add missing regulator
The regulator framework is used for power management. The regulators are
only named in the driver code, the actual control stuff is in the board
file for each architecture or use case.
The PN544 chip has three regulators that can be controlled or not -
depending on the architecture where the chip is being used. So some of
the regulators may not be controllable. In our current case the third
regulator, which was missing from the code, went unnoticed because we
didn't need to control it. To be as general as possible - in this respect
- the driver needs to list all regulators. Then the board file can be
used to actually set the usage.

epoll: prevent creating circular epoll structures
In several places, an epoll fd can call another file's ->f_op->poll()
method with ep->mtx held. This is in general unsafe, because that other
file could itself be an epoll fd that contains the original epoll fd.
The code defends against this possibility in its own ->poll() method using
ep_call_nested, but there are several other unsafe calls to ->poll
elsewhere that can be made to deadlock. For example, the following simple
program causes the call in ep_insert recursively call the original fd's
->poll, leading to deadlock:
#include <unistd.h>
#include <sys/epoll.h>
int main(void) {
int e1, e2, p[2];
struct epoll_event evt = {
.events = EPOLLIN
};
e1 = epoll_create(1);
e2 = epoll_create(2);
pipe(p);
epoll_ctl(e2, EPOLL_CTL_ADD, e1, &evt);
epoll_ctl(e1, EPOLL_CTL_ADD, p[0], &evt);
write(p[1], p, sizeof p);
epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt);
return 0;
}
On insertion, check whether the inserted file is itself a struct epoll,
and if so, do a recursive walk to detect whether inserting this file would
create a loop of epoll structures, which could lead to deadlock.

The variable 'val' is a 'unsigned int', so it can never be less than zero.
This fact makes the "val < 0" part of the test done in BUG_ON() in
mc13xxx_regulator_get_voltage() rather pointles since it can never have
any effect.
This patch removes the pointless test.
