for the Getattr and Recall callbacks. This patch fixes it.
Since the NFSv4.1 specific error codes would only happen for
abnormal circumstances, this patch has little effect, in practice.

libkafs5 needs a header from libkrb5, it includes this from
${.OBJDIR}/mumble, this used to work fine as long as you happen to have
a krb_err.h in your base system, this doesn't work for bootstrapping or
using a cross-compiler with a different sysroot. This is just a
best-effort bandaid, sufficient parallelism can still break it.
Fix a SRCS override that dropped krb5_err.h.

Instead of taking 8 specific bytes of file handle to identify file during
RPC thread affitinity handling, use trivial hash of the full file handle.
ZFS's struct zfid_short does not have padding field after the length field,
as result, originally picked 8 bytes are loosing lower 16 bits of object ID,
causing many false matches and unneeded requests affinity to same thread.
This fix substantially improves NFS server latency and scalability in SPEC
NFS benchmark by more flexible use of multiple NFS threads.

capture mode together with the timecounter's PPS polling feature to get
very accurate PPS capture without any interrupt processing (or latency).
Hardware timers 4 through 7 have associated capture-trigger input pins.
When the PPS support is compiled in the code automatically chooses the
first timer it finds that has the capture-trigger pin set to input mode
(this is configured via the fdt data).
- Use named constants for register bits, instead of mystery numebrs
scattered around in the code.
- Use inline functions for bus space read/write, instead of macros
that rely on global variables.
- Move the timecounter struct into the softc instead of treating it
as a global variable. Backlink from it to the softc.
- This leaves a pointer to the softc as the only static/global variable
and it's now used only by DELAY().
state before the requested state transition. This guarantees that there is
exactly one ioctl() operating on a vcpu at any point in time and prevents
unintended state transitions.

clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:
CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc
In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

The priority goes from "error" to "debug".
Connectors are polled every 10 seconds. Reading EDID is part of this
polling. However, when an invalid EDID is returned, this error message
is logged. When using Newcons for instance, having a kernel message
every 10 seconds is getting annoying.
Now that it's a debug message, it'll be logged only if hw.dri.debug is
enabled. This fix console spamming for some users.

even the initial Install dialog can benefit from the change).

clients. Mask RX interrupts while grabbed on the atmel serial
driver. This UART interrupts every character. When interrupts are
enabled at the mountroot> prompt, this means the ISR eats the
characters. Rather than try to create a cooperative buffering system
for the low level kernel console, instead just mask out the ISR. For
NS8250 and decsendents this isn't needed, since interrupts only happen
after 14 or more characters (depending on the fifo settings). Plumb
such that these are optional so there's no change in behavior for all
the other UART clients. ddb worked on this platform because all
interrupts were disabled while it was running, so this problem wasn't
noticed. The mountroot> issue has been around for a very very long
time.

... for msleep/cv_*wait() return values, where wait_event*() is used
on Linux. ERESTARTSYS is the return code expected by callers when the
operation was interrupted.
For instance, this is the case of radeon_cs_ioctl() (radeon_cs.c): if
an error occurs, and the code isn't ERESTARTSYS (eg. EINTR), it logs an
error.
Note that ERESTARTSYS is defined as ERESTART, but this keeps callers'
code close to Linux.
