0dd10c0047 Don't include the guest memory segments in the bhyve(8) process core dump.
This has not added a lot of value when debugging bhyve issues while greatly
increasing the time and space required to store the core file.

Passing the "-C" option to bhyve(8) will change the default and dump guest
memory in the core dump.

afaa41f6b8 On a fork allow read-only wired pages to be copy-on-write shared between the
parent and child processes.  Previously, we copied these pages even though
they are read only.  However, the reason for copying them is historical and
no longer exists.  In recent times, vm_map_protect() has developed the
ability to copy pages when write access is added to wired copy-on-write
pages.  So, in this case, copy-on-write sharing of wired pages is not to be
feared.  It is not going to lead to copy-on-write faults on wired memory.

74a034464e Disable TX IP/TCP/UDP checksum offloading for RTL8168C/RTL8168CP.
Previously only TX IP checksum offloading was disabled but it's
reported that TX checksum offloading for UDP datagrams with IP
options also generates corrupted frames.  Reporter's controller is
RTL8168CP but I guess RTL8168C also have the same issue since it
shall share the same core.

02bb9ba1cc Interrupts need to be disabled on entry to cpu_sleep() for ARM. Given
that and the need to be in a critical section when switching to idleclock
mode for event timers, use spinlock_enter()/exit() to achieve both needs.

The ARM WFI (wait for interrupt) instruction blocks until an interrupt is
asserted, and it will unblock even if interrupts are masked, and it will
unblock immediately if an interrupt is already pending.  It is necessary
to execute it with interrupts disabled, otherwise the interrupt that
should unblock it may occur and be serviced just prior to executing the
instruction.  At that point the system is inappropriately asleep until
the next timer tick or some other random interrupt happens.

In general, interrupts need to be disabled continuously from the time the
decision is made that there is no work to be done and sleeping is needed
until actually going to sleep, to avoid a race where handling a new
interrupt changes the basis for deciding there is no work to be done.

0c50edff52 Repair some races in IPI handling:
1. Make sure IPI mask is set before sending the IPI
2. Operate atomically on PS3 PIC outstanding interrupt list
3. Make sure IPIs are EOI'ed before, not after, processing. Without this,
   a second IPI could be sent partway through processing the first one,
   get erroneously acknowledge by the EOI to the first, and be lost. In
   particular in the case of smp_rendezvous(), this can be fatal.

In combination, this makes the PS3 boot SMP again. It probably also fixes
some latent bugs elsewhere.

8783345b6c Attempt to walk a fine line between current usage (/usr/ports which
does an out-of-tree build without setting MAKESYSPATH) and recently
added requirements (JIRA's building the modules in a non-standard
layout). So, when MAKESYSPATH is defined, trust that it will do the
right thing (to catch the JIRA use case). When it isn't defined,
assume a standard FreeBSD tree and reach over to grab bsd.mkopt.mk (to
fix the /usr/ports use case). Both camps cannot be appeased otherwise,
so we have this kludge until it can be sorted out.

857ce8a246 accept(),accept4(): Don't set *addrlen = 0 on [ECONNABORTED].
If the underlying protocol reported an error (e.g. because a connection was
closed while waiting in the queue), this error was also indicated by
returning a zero-length address. For all other kinds of errors (e.g.
[EAGAIN], [ENFILE], [EMFILE]), *addrlen is unmodified and there are
successful cases where a zero-length address is returned (e.g. a connection
from an unbound Unix-domain socket), so this error indication is not
reliable.

As reported in Austin Group bug #836, modifying *addrlen on error may cause
subtle bugs if applications retry the call without resetting *addrlen.

dd006a1b14 With the new-and-improved vm_fault_copy_entry() (r265843), we can always
avoid soft page faults when adding write access to user wired entries in
vm_map_protect().  Previously, we only avoided the soft page fault when
the underlying pages were copy-on-write.  In other words, we avoided the
pages faults that might sleep on page allocation, but not the trivial
page faults to update the physical map.

760f4dec67 In cf_get_method, when we don't already know what clock speed the CPU is
running at, guess the nearest value instead of looking for a value within
25 MHz of the observed frequency.

Prior to this change, if a system booted with Intel Turbo Boost enabled,
the dev.cpu.0.freq sysctl is nonfunctional, since the ACPI-reported
frequency for Turbo Boost states does not match the actual clock frequency
(and thus no levels are within 25 MHz of the observed frequency) and the
current performance level is read before a new level is set.

b07d0cbce3 Add cpu_l2cache_drain_writebuf(), use it to implement generic_bs_barrier().
On modern ARM SoCs the L2 cache controller sits between the CPU and the
AXI bus, and most on-chip memory-mapped devices are on the AXI bus.  We
map the device registers using the 'Device' memory attribute, which means
the memory is not cached, but writes to it are buffered.  Ensuring that a
write has made it all the way to a device may require that the L2
controller take some action.

There is currently only one implementation of the new function, for the
PL310 cache controller.  It invokes a function that the controller
manual calls "cache sync" but it actually has nothing to do with cache at
all, it triggers a drain of all pending store buffer writes and it blocks
until they complete.

The sheeva and xscale L2 controllers (which predate the concept of Device
memory) don't seem to have a corresponding function.  It appears that the
standard armv5 drain_writebuf function includes draining all the way
through the L2 controller.

015ac42e4b Make ofwfb not be painfully slow. This reduces the time for a verbose boot
on my G4 iBook by more than half. Still 10% slower than syscons, but that's
much better than a factor of 2.

The slowness had to do with pathological write performance on 8-bit
framebuffers, which are almost universally used on Open Firmware systems.
Writing 1 byte at a time, potentially nonconsecutively, resulted in many
extra PCI write cycles. This patch, in the common case where it's writing
one or several characters in an 8x8 font, gangs the writes together into
a set of 32-bit writes. This is a port of r143830 to vt(4).

The EFI framebuffer is also extremely slow, probably for the same reason,
and the same patch will likely help there.
