7af72453b7 If full width writes to the performance monitoring counters are
supported, use full-width aliases MSRs for writes.  This fixes the
"[pmc,X] negative increment" assertion on the context switch when
clipped counter value is sign-extended.

Add definitions for the MSR IA32_PERF_CAPABILITIES needed to detect
the feature.

f0d593add5 o Gather all mbuf(9) allocation functions into kern_mbuf.c, and all
mbuf(9) manipulation functions into uipc_mbuf.c.  This looks like
  the initial intent, but had diffused in the last decade.

o Gather all declarations in mbuf.h in one place and sort them.

o Uninline m_clget() and m_cljget().

There are no functional changes in this patch.

The patch comes from a larger version, where all mbuf(9) allocation was
uninlined, which allowed to make mbuf(9) UMA zones private to kern_mbuf.c.
The performance impact of the total uninlining is still unclear, so we
are holding on now with larger version.

4deaf20e8b nvme: avoid duplicate SET_NUM_QUEUES commands
nvme(4) issues a SET_NUM_QUEUES command during device
initialization to ensure enough I/O queues exists for each
of the MSI-X vectors we have allocated.  The SET_NUM_QUEUES
command is then issued again during nvme_ctrlr_start(), to
ensure that is properly set after any controller reset.

At least one NVMe drive exists which fails this second
SET_NUM_QUEUES command during device initialization.  So
change nvme_ctrlr_start() to only issue its SET_NUM_QUEUES
command when it is coming out of a reset - avoiding the
duplicate SET_NUM_QUEUES during device initialization.

323ead721e Migrate the PTE format for book-e to standardize on the 'indirect PTE' format
Summary:
The revised Book-E spec, adding the specification for the MMUv2 and e6500,
includes a hardware PTE layout for indirect page tables.  In order to support
this in the future, migrate the PTE format to match the MMUv2 hardware PTE
format.

Test Plan: Boot tested on a P5020 board.  Booted to multiuser mode.

45b4fa372e Fix bugs in interrupts allocation on ARM64
Separate interrupt descriptors lookup from allocation. It was possible
to perform config on non-existing interrupt simply by allocating spurious
descriptor.
Must lock the interrupt descriptors table lookup to avoid mismatches.
This ought to prevent trouble while setting up new interrupt
and dispatching existing one.
Use spin mutex rather than sleep mutex. This is mainly due to lock in
arm_dispatch_intr.
This should be eventually changed to a lock-less solution without
walking through a linked list on each interrupt.

dd3b3e6ad6 Begin the MIPS_INTRNG support.
This is a prelude to intr-ng support for MIPS boards that need it -
notably the CI20 port from kan@ that's upcoming, but also work that
Stanislav is doing for the Mediatek platforms.

This is the initial platform dependent bits in include/intr.h, some
#defines for the nexus code for the intrng initialisation/runtime
bits, some changed naming (which I'll fix later to be the same, much
like what I did for ARM intr-ng) in exception.S, and the first cut
at a PIC.

Stanislav and I refactored out the common code for intrng support,
so the mips intrng definitions are quite small (sys/mips/include/intr.h.)

This is all work done by kan@, which stanislav has been cherry picking
into common code for his mediatek chipset work.

Tested:

* Carambola2 - no regressions (not intr-ng though!)

cdb1cc5394 Ext4: fix handling of files with sparse blocks before extent's index.
This is ongoing work from Damjan Jovanovic to improve ext4 read support
with sparse files:

Keep track of the first and last block in each extent as it descends down
the extent tree, thus being able to work out that some blocks are sparse
earlier. This solves an issue on r293680.

In ext4_bmapext() start supporting the runb parameter, which appears to be
the number of adjacent blocks prior to the block being converted in the
same way that runp is the number of blocks after, speding up random access
to mmaped files.
