hwpmc: remove stub pmd_switch_{in,out} methods
Most platforms (non-x86) don't require these methods and implement stub
versions. If we initialize the pmc_mdep structure to always point to the
generic versions, then we can purge the duplicate stubs.

hwpmc: pass pmc pointer to more class methods
In many cases this avoids an extra lookup, since the callers always have
pm at hand. We can also eliminate several assertions, mostly for pm !=
NULL. The class methods are an internal interface, and the callers
already handle such a scenario. No functional change intended.

hwpmc_logging: less macro magic for type names
Provide the log type names in their entirely, rather than relying on the

to find where that is emitted in the kernel with a simple grep.

hwpmc: remove remaining UCP event definitions
Although this block has remained in __PMC_EVENTS(), there is no handling
of UCP in libpmc/libpmc.c, so it is not possible to select one of these
events. It should therefore be impossible to trigger the code removed
from ucp_start_pmc(). Note that the GQ_SNOOP_MSF MSR exists only for
Nehalem and Westmere architectures, and the related events do not exist
for later generations.
The Uncore support in hwpmc has severely atrophied in general. We have
uncore event definitions in pmu-events, but the kernel support was
written against Intel Performance Measurement Architecture version 2,
and is disabled for processor generations later than Westmere. Nehalem
and Westmere lack uncore event definitions in pmu-events. I'd be
surprised if Uncore support is usable on any machine in its current
state.

ffs: restore backward compatibility of newfs and makefs with older binaries
The previous change to CGSIZE had the unintended side-effect of allowing
newfs and makefs to create file systems that would fail validation when
examined by older commands and kernels, by allowing newfs/makefs to pack
slightly more blocks into a CG than those older binaries think is valid.
Fix this by having newfs/makefs artificially restrict the number of blocks
in a CG to the slightly smaller value that those older binaries will accept.
The validation code will continue to accept the slightly larger value
that the current newfs/makefs (before this change) could create.
This patch fixes TCP connection hangs for 1 rxq and 1 txq without rxcsum
enabled. Documentation for 10G cards and other drivers suggest enabling
rxcsum for RSS and disabling otherwise. When PCSD bit is not set then
fragment checksum and IP identification are reported in the rx
descriptor. When PCSD bit is set then RSS hash value is reported in the
rx descriptor. RSS and RX IPP checksum are mutually exclusive.

MFC: listen(2): improve administrator control over logging
As documented in listen.2 manual page, the kernel emits a LOG_DEBUG
syslog message if a socket listen queue overflows. For some appliances,
it may be desirable to change the priority to some higher value
like LOG_INFO while keeping other debugging suppressed.
OTOH there are cases when such overflows are normal and expected.
Then it may be desirable to suppress overflow logging altogether,
so that dmesg buffer is not flooded over long run.
In addition to existing sysctl kern.ipc.sooverinterval,
introduce new sysctl kern.ipc.sooverprio that defaults to 7 (LOG_DEBUG)
to preserve current behavior. It may be changed to any value
in a range of 0..7 for corresponding priority or to -1 to suppress logging.
Document it in the listen.2 manual page.
