From now on, default values for FreeBSD will be 64 maxiumum supported
CPUs on amd64 and ia64 and 128 for XLP. All the other architectures
seem already capped appropriately (with the exception of sparc64 which
needs further support on jalapeno flavour).
Bump __FreeBSD_version in order to reflect KBI/KPI brekage introduced
during the infrastructure cleanup for supporting MAXCPU > 32. This
covers cpumask_t retiral too.
The switch is considered completed at the present time, so for whatever
bug you may experience that is reconducible to that area, please report
immediately.

not.
Flag several useful sysctls as available in capability mode, such as memory
layout sysctls required by the run-time linker and malloc(3). Also expose
access to randomness and available kernel features.
A few sysctls are enabled to support name->MIB conversion; these may leak
information to capability mode by virtue of providing resolution on names
not flagged for access in capability mode. This is, generally, not a huge
problem, but might be something to resolve in the future. Flag these cases
with XXX comments.

sampling mode PMC is allocated, hwpmc calls linker_hwpmc_list_objects()
while already holding an exclusive lock on pmc-sx lock. list_objects()
tries to acquire an exclusive lock on the kld_sx lock. When a KLD module
is loaded or unloaded successfully, kern_kld(un)load calls into the pmc
hook while already holding an exclusive lock on the kld_sx lock. Calling
the pmc hook requires acquiring a shared lock on the pmc-sx lock.
Fix this by only acquiring a shared lock on the kld_sx lock in
linker_hwpmc_list_objects(), and also downgrading to a shared lock on the
kld_sx lock in kern_kld(un)load before calling into the pmc hook. In
kern_kldload this required moving some modifications of the linker_file_t
to happen before calling into the pmc hook.
This fixes the deadlock by ensuring that the hwpmc -> list_objects() case
is always able to proceed. Without this patch, I was able to deadlock a
multicore system within minutes by constantly loading and unloading an KLD
module while I simultaneously started a sampling mode PMC in a loop.

Therefore, assemble the resulting .s files with clang instead. A more

Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls

for the old calls, but I didn't get any feedback to that.
It seems now people are upgrading from 8 to 9 they experience this
issue, so add it anyway.
for the remove and rename operations. Some NFSv4 servers will
report NFSERR_GRACE for these operations. This patch changes
the behaviour of the client so that it handles NFSERR_GRACE
like NFSERR_DELAY for non-state related operations like
remove and rename. It also exempts the delegreturn operation
from handling within newnfs_request() for NFSERR_DELAY/NFSERR_GRACE
so that it can handle NFSERR_GRACE in the same manner as before.
This problem was resolved thanks to discussion with bfields at fieldses.org.
The problem was identified at the recent NFSv4 ineroperability

addresses (i.e. uncacheable). ACPI in particular uses pmap_mapdev()
rather excessively (number of calls) just to get a valid KVA. To
that end, have pmap_mapdev():
1. cache the last result so that we don't waste time for multiple
consecutive invocations with the same PA/SZ.
2. find the memory descriptor that covers the PA and return NULL
if none was found or when the PA is for a common DRAM address.
3. Use either a region 6 or region 7 KVA, in accordance with the
memory attribute.
This patch adds support for the Netlogic XLP mips64 processors in
the common MIPS code. The changes are :
- Add CPU_NLM processor type
- Add cases for CPU_NLM, mostly were CPU_RMI is used.
- Update cache flush changes for CPU_NLM
- Add kernel build configuration files for xLP.

potentially trigger multiple pending interrupts for level-sensitive
interrupts. However, the event timer interrupt does need EOI before
being handled to avoid missing clock events.
These conflicting requirements are handled by having the XIV handler
inform the dispatch code whether or not it send EOI to the CPU. If not,
the dispatch code will do it. This allows handlers to send EOI before
doing potentially long-running activities, while still have a sensible
default behaviour.
