usb: gadget: f_fs: Fix enumeration in fullspeed mode

ffs_func_eps_enable always take the highspeed usb_endpoint_descriptor
if it is available. Choose the correct usb_endpoint_descriptor
depending on the gadget speed instead.

cpufreq: interactive: always limit initial speed bump to hispeed

First bump speed up to hispeed_freq whenever the current speed is below
hispeed_freq, instead of only when the current speed is the minimum speed.
The previous code made it too difficult to use hispeed_freq as a common
intermediate speed on systems that frequently run at speeds between
minimum and hispeed_freq.

The conversion to use oom_score_adj instead of the deprecated oom_adj

oom_adj values written to oom_score_adj values if they appear to be
valid oom_adj values.

timekeeping: fix 32-bit overflow in get_monotonic_boottime

get_monotonic_boottime adds three nanonsecond values stored
in longs, followed by an s64.  If the long values are all
close to 1e9 the first three additions can overflow and
become negative when added to the s64.  Cast the first
value to s64 so that all additions are 64 bit.

cpufreq: interactive: run at fraction of hispeed_freq when load is low

When load is below go_hispeed_load, apply the percentage of CPU load to
a max frequency of hispeed_freq instead of the max speed.  This avoids
jumping too quickly to hispeed_freq when it is a relatively low
percentage of max speed.  This also allows go_hispeed_load to be set to
a high percentage relative to hispeed_freq (as a percentage of max speed,
again useful when hispeed_freq is a low fraction of max speed), to cap
larger loads at hispeed_freq.  For example, a load of 60% will typically
move to 60% of hispeed_freq, not 60% of max speed.  This causes the
governor to apply two different speed caps, depending on whether load is
below or above go_hispeed_load.

Also fix the type of hispeed_freq, which was u64, to match other
speed data types (and avoid overhead and allow division).

mm: vmscan: Add a debug file for shrinkers

This patch adds a debugfs file called "shrinker" when read this calls
all the shrinkers in the system with nr_to_scan set to zero and prints
the result.  These results are the number of objects the shrinkers have
available and can thus be used an indication of the total memory
that would be availble to the system if a shrink occurred.
