consumers can configure clock frequency
- Add ti_prcm_clk_set_source_freq wrapper for clk_set_source_freq
- Add am335x_clk_set_arm_disp_freq function to control pixel clock
frequency for LCD and HDMI output. Both of them are sensitive
to frequency skews and we need to get pixel clock matching requested
frequency as close to possible

The problem is that when inline versions of flsl and flsll are not
available, then libkern.h must be included for their declarations
in kernel sources.
The fix would be trivial, but I would like to figure out first if
it even makes sense to use the libkern provided implementations.

b_size is a logical size of a buffer in memory, b_asize is its physical
size that accounts for possible compression.
Currently the latter is the best approximation for the allocated, on-disk
size.
L2ARC TRIM support was committed a few weeks before L2ARC compression
was imported, so originally the code was correct, because b_size was
the size.
Further thoughts. Given that the cache device is being overwritten
in a circular fashion it is not clear if a TRIM per each evicted L2ARC
buffer has any benefits.
Maybe it would be sufficient to issue a single trim request for the whole
device when it is loaded, e.g. after a bootup, or when it is unloaded, e.g.
before a shutdown. At least as long as L2ARC is not persistent across
reboots.

to be transmitted but the arp cache entry expired, which triggers an arp request
to be sent, the bpf code might want to sleep but crash the system due
to a non sleep lock held from the arp entry not released properly.
Release the lock before calling the arp request code to solve the issue
as is done on all the other code paths.

the active vnode list for the given mount point, with the assumption
that vnodes with dirty pages are active. This is enforced by
vinactive() doing vm_object_page_clean() pass over the vnode pages.
The issue is, if vinactive() cannot be called during vput() due to the
vnode being only shared-locked, we might end up with the dirty pages
for the vnode on the free list. Such vnode is invisible to syncer,
and pages are only cleaned on the vnode reactivation. In other words,
the race results in the broken guarantee that user data, written
through the mmap(2), is written to the disk not later than in 30
seconds after the write.
Fix this by keeping the vnode which is freed but still owing
inactivation, on the active list. When syncer loops find such vnode,
it is deactivated and cleaned by the final vput() call.

crypt_blowfish and many implementations based on it (Apache, PHP, PostgreSQL) implemented $2y$ before OpenBSD went with $2b$. This changes marks them as equivalent.
http://www.openwall.com/lists/announce/2011/07/17/1
This change is required for applications that use the base crypt() implementation (including nginx) to be able to validate $2y$ hashes

syslogd already re-reads the configuration file and the hostname when
receiving a SIGHUP, so it makes sense to reset the timezone.
Special care was taken to ensure we don't break installations running

advisory includes a change which rejects handshakes with DH parameters
below 768 bits. sendmail releases prior to 8.15.2 (not yet released),
defaulted to a 512 bit DH parameter setting for client connections.
This commit chages that default to 1024 bits. sendmail 8.15.2, when
released well use a default of 2048 bits.
