media: s5p-mfc: Add support for V4L2_MEMORY_DMABUF type
There is memory constraint that it should be within 128MB from
firmware address. But if IOMMU is supported, then this constraint
is meaningless and DMABUF importing can be used.
So this patch adds V4L2_MEMORY_DMABUF type support for both decoder
and encoder.

phy: exynos : add delay after reset phy for usb host
The commit
2b431ff74a850db3d5b804be3ac466b6ed7f516d(ARM: EXYNOS4:
Increase reset delay for USB HOST PHY) uses 80 usec delay time after

math64: New separate div64_u64_rem helper
Commit
f792685006274a850e6cc0ea9ade275ccdfc90bc ("math64: New
div64_u64_rem helper") implemented div64_u64 in terms of div64_u64_rem.
But div64_u64_rem was removed because it slowed down div64_u64 (and
there were no other users of div64_u64_rem).
Device Mapper's I/O statistics support has a need for div64_u64_rem;
reintroduce this helper as a separate method that doesn't slow down
div64_u64, especially on 32-bit systems.

cpufreq: ondemand: Change the calculation of target frequency
The ondemand governor calculates load in terms of frequency and
increases it only if load_freq is greater than up_threshold
multiplied by the current or average frequency. This appears to
produce oscillations of frequency between min and max because,
for example, a relatively small load can easily saturate minimum
frequency and lead the CPU to the max. Then, it will decrease
back to the min due to small load_freq.
Change the calculation method of load and target frequency on the
basis of the following two observations:
- Load computation should not depend on the current or average
measured frequency. For example, absolute load of 80% at 100MHz
is not necessarily equivalent to 8% at 1000MHz in the next
sampling interval.
- It should be possible to increase the target frequency to any
value present in the frequency table proportional to the absolute
load, rather than to the max only, so that:
Target frequency = C * load
where we take C = policy->cpuinfo.max_freq / 100.
Tested on Intel i7-3770 CPU @ 3.40GHz and on Quad core 1500MHz Krait.
Phoronix benchmark of Linux Kernel Compilation 3.1 test shows an
increase ~1.5% in performance. cpufreq_stats (time_in_state) shows
that middle frequencies are used more, with this patch. Highest
and lowest frequencies were used less by ~9%.
[rjw: We have run multiple other tests on kernels with this
change applied and in the vast majority of cases it turns out
that the resulting performance improvement also leads to reduced
consumption of energy. The change is additionally justified by
the overall simplification of the code in question.]

The freeing through free_hot_cold_page() is okay because
freepage migratetype is set to pageblock migratetype before

migratetype end up on the free lists of other migratetype
whole Reserved pageblock may be later changed to the other

for MIGRATE_RESERVE migratetype pages in rmqueue_bulk().

Ability of read from or write to ep0 file is related with actual state of ffs:
- When desctiptors or strings are not written yet, POLLOUT flag is set.
- If there is any event to read, POLLIN flag is set.
- If setup request was read, POLLIN and POLLOUT flag is set, to allow
send response (by performing I/O operation consistent with setup request
direction) or set stall (by performing I/O operation opposite setup
request direction).

usb: gadget: f_fs: fix setup request handling
This patch fixes __ffs_ep0_queue_wait() function, which now returns number of
bytes transferred in USB request or error code in case of failure. This is
needed by ffs_ep0_read() function, when read data is copied to userspace.
It also cleans up code by removing usused variable ep0req_status.

usb: gadget: functionfs: replace FFS_SETUP_STATUS with an inline function
The FFS_SETUP_STATUS macro could be trivialy replaced with an static
inline function but more importantly its name was tad confusing.
The name suggested it was a simple accessor macro but it actually
did change the state of the ffs_data structure perfomring
a FFS_SETUP_CANCELLED -> FFS_NO_SETUP transition. The name of the
function -- ffs_setup_state_clear_cancelled -- should better
describe what the function actually does.
