Current Xen resume code clears all pending bitmap IPIs on resume, which is
not correct. Instead re-inject bitmap IPI vectors on resume to all CPUs in
order to acknowledge any pending bitmap IPIs.

This is needed so interrupt handlers can be removed while the PIC is
resuming, it was previously not possible due to intr_resume holding the
intr_table_lock and intr_remove_handler recursing on it.

Drivers can request DMA to buffers that are not in memory represented
in the vm page arrays. Because of this, store KVA of already mapped
buffer to synclist and use it in dma_dcache_sync().

pmcstat(8) contains an option to output sampling data in a gmon format
compatible with gprof(1). Currently, it uses the default histcounter,
which is an (unsigned short). With large sets of sampling data, it
is possible to overflow the maximum value provided by an (unsigned
short).
This change adds the -e argument to pmcstat. If -e and -g are both
specified, pmcstat will use a histcounter type of uint64_t.

Modern cards in most cases operate abstract port handles, that have no

While there, fix few more cases where LUNs were still printed in decimal.

Wifi doesn't work on the QCA9533 board, but basic ethernet/ethernet
and ethernet switch support does work.
The AP143 has 32MB RAM and 4MB flash, so this was tested with a USB
rootfs.
Tested:
* QCA9533v2, AP143 reference design board.
It turns out on a 16550 w/ a 25MHz SoC reference clock you get a little
over 3% error at 115200 baud, which causes this to fail.
Just .. cope. Things cope these days.
Default to 30 (3.0%) as before, but allow UART_DEV_TOLERANCE_PCT to be
set at build time to change that.
QorIQ SoCs (e5500 core, P5 family) have 2 BARs for local access windows, while
MPC85XX, and P1/P2 families use only a single BAR register.
This also adds the QORIQ_DPAA option, mutually exclusive to MPC85XX, to handle
this difference.

Setting the dumpdev via env e.g. loader.conf provides the ability to
configure the kernel dump device during early boot. When using this
g_io_getattr was returning EPERM due to cp->acr == 0.
Fix this by calling g_access to ensure we're a read consumer prior
to calling g_dev_setdumpdev.

OF_getprop() to get encode-int encoded values from the OF tree. This is
a no-op at present, since all existing PowerPC ports are big-endian, but
it is a correctness improvement and will be required if we have a
little-endian kernel at some future point.
Where it is totally impossible for the code ever to be used on a
little-endian system (much of powerpc/powermac, for instance), I have not
necessarily made the appropriate changes.

This structure must be binary compatible regardless of PMAP
version being used. Create reserved section for NEW_PMAP to
make other variables be placed exactly in the same memory
addresses. This fixes kgdb/gdb behavoiur, which uses pcb.h stuctures.
The NEW_PMAP is kernel flag, so it does not propagate to the buildworld,
what makes the tools using pcb.h unable to parse PCB data.

the largest size of buffer cache block or the mapping of the buffer
is bogus. When a mount with rsize=4096,wsize=4096 was done, f_iosize
would be set to 4096. This resulted in corrupted directory data, since
the buffer cache block size for directories is NFS_DIRBLKSIZ (8192).
This patch fixes the code so that it always sets f_iosize to at least
NFS_DIRBLKSIZ.

would call smb_iod_request(). This call could return as soon as the
wakeup(evp) in smb_iod_main() call is done and then could destroy
the mutexes. This caused a race with the rest of smb_iod_main()s
use of these mutexes.
A crash reported on freebsd-stable@ by Christian Kratzer was
diagnosed as a use of one of these mutexes after it was destroyed.
This patch moves destruction of the mutexes from smb_iod_destroy()
to the end of smb_iod_thread(), so that they aren't destroyed before
the thread is done with them. Christian comfirmed that the patch
stopped the crashes from happening.
