Revert r274918 and make a better solution. Poll the synchronisation
endpoint less frequently to make the sample rate adjustment more
accurate. This should resolve problems with the DN32-USB module for
Midas audio systems and possibly other similar products from Klark
Teknik.
Split syscall handling out to a separate file.
Include sys/kernel.h to pick up the definition of hz in syscall.c
Add a new trap-v6.c which has support for all armv7 exceptions.
Put in a workaround for bug 196407 (arm modules cause crashes & panics).
(Don't allow movw/movt insn in modules.)
Fix alignment directives in arm asm code after clang 3.5 import.

Explicitly return None for negative event indices. Prior to this,
eventat(-1) would return the next-to-last event causing the back button
to cycle back to the end of an event source instead of stopping at the
start.
r272757
Add schedgraph traces for callout handlers. Specifically, a callwheel logs
a running event each time it executes a callout function. The event
includes the function pointer, argument, and whether or not it was run from
hardware interrupt context. The callwheel is marked idle when each handler
completes. This effectively logs the duration of each callout routine in
the graph.
r274091
Bind Ctrl-Q as a global hotkey to exit. Bind Ctrl-W as a hotkey to close
dialogs.
r274902
Add a new thread state "spinning" to schedgraph and add tracepoints at the
start and stop of spinning waits in lock primitives.

Fix a paste-o in dcache_inv_pou_all().
Change the order of operations for the initial cache setup.
A couple small fixes to make clang 3.5 happy... Move END(sigcode)
and other misplace ENTRY/END macros.
Include acle-compat.h directly rather than getting it via sysreg.h.
Add new code to read and parse cpu identification data using the new CPUID
mechanism defined for armv7.
Add new TLB and cache maintainence functions for armv6 and armv7.
Eliminate an unused macro whose name clashes now with a function in the
new cpu-v6.h
Add cache maintenance functions which will be used by startup code to
initially set up the MMU.
Fix a "decl is not a prototype" error noticed by gcc (but not clang).
Update comments (r4 is not used anywhere), use non-profiling entry macros.
Add arm option ARM_NEW_PMAP, to allow us to begin adding the new pmap
code alongside the existing implementation
Add armv6 implementations of cache operations to avoid duplication
Add machine/sysreg.h to simplify accessing the system control coprocessor
registers and use it in the ARMv7 CPU functions.
Add macros for asm barrier instructions with arch-specific implementations.
Define only the CP15 register operations that are valid for the architecture.
For data and instruction prefetch aborts, call the same handler in the C
code, passing a 0/1 flag that indicates which type of abort it was. This
sets the stage for unifying the handling of page faults in a single routine.
Change the style of the DO_AST macro to match the others
Remove _PROF_PROLOGUE from the EENTRY() macros.
Stylish changes... put tabs where they need to be in macros, move lines
around so that related things are more grouped together, rewrite comments.
Fix the GLOBAL macro so it works (upper vs lowercase X), use it in _EENTRY.
Create 'L' variants of all the ENTRY macros for file-static/local symbols.
Rename pmap_kenter_temp to pmap_kenter_temporary to be consistent with the
other architectures with this function.
Eliminate unnecessary references to pte.h internals by using the standard
pmap_kenter_temporary() to map pages while dumping.
Cleanup up ARM *frame structures.
Add more register values to armreg.h and remove CPU_CONTROL_32BP_ENABLE
from asm.h as they were already defined in armreg.h.
Unify interrupts bit definition and usage. While here remove PSR_C_bit.
Move ofw_cpu.c to sys/dev/ofw so that it can be used by other
architectures.
Add driver for CPU frequency/voltage control on the Raspberry Pi.
On initialization, do not use bcm_mbox_intr() to read the pending messages.
This fixes the hang that happens on boot while initializing the cpufreq on
Raspberry Pi.
Add a divisor parameter to twiddle() so that callers can request that

Add a new loader(8) variable, twiddle_divisor, allowing control over the

ipfilter 5.1.2 (vs 4.1.28 in previous releases of FreeBSD) stores IPv4

including IPv4 rules. This patch removes the redundant ipf -I -6 -Fa
statement.

- Switching the mode of Ricoh R5CE823 to SD2.0 causes their PCI device ID
to change to 0xe822, which may be persistent across reboots and, thus,
confuse other OSes. Therefore, restore the original mode and frequency
setting on detach and shutdown.
- Report Ricoh R5CE822 as such.
- According to Linux, Ricoh R5CE822 also need SDHCI_QUIRK_LOWER_FREQUENCY.
- Nuke an unused softc member.
Use an sbuf to generate the output of the net.inet.tcp.hostcache.list
sysctl to avoid a possible buffer overflow if the cache grows while the

Rework virtual machine hypervisor detection.
- Move the existing code to x86/x86/identcpu.c since it is x86-specific.
- If the CPUID2_HV flag is set, assume a hypervisor is present and query
the 0x40000000 leaf to determine the hypervisor vendor ID. Export the
vendor ID and the highest supported hypervisor CPUID leaf via
hv_vendor[] and hv_high variables, respectively. The hv_vendor[]
array is also exported via the hw.hv_vendor sysctl.
- Merge the VMWare detection code from tsc.c into the new probe in
identcpu.c. Add a VM_GUEST_VMWARE to identify vmware and use that in
the TSC code to identify VMWare.
