done on the old keyboard and then do the corresponding number of grabs
on the new keyboard.
This fixes a race that can leave the system with a non-functioning
keyboard. It goes like this...
- The bios claims there is an AT keyboard, atkbd attaches.
- SI_SUB_INT_CONFIG_HOOKS runs.
- USB probes devices. Devices begin attaching, including disks.
- GELI prompts for a password for a just-attached disk, which results
in a cngrab() while atkbd is the keyboard.
- A USB keyboard attaches.
- vt_upgrade() runs and switches the keyboard to the new USB keyboard,
but because cngrab was never called for it, it's not activated and
keystrokes are ignored.
- Now there is no functional keyboard and no way to get one; even
plugging in a different USB keyboard doesn't help, because the console
is still grabbed, still waiting for a GELI pw.

When using a gmirror, entries in /dev can be removed. So instead of using
kern.disks, get the list of disks from "gpart status -sg" instead.
We assume that any 'efi' partition that can't be mounted as msdosfs should
be used as an ESP. However, the ESP on the CD/DVD can't be mounted read-write
and so was being treated as if unformatted. Try the mount as read-only
instead, to catch cases like this.

Instead of passing the bootnum to each different parameter, require users
to specify -b when running operations that need a bootnum.
This allows activation of a new boot entry at the same time it's created
by adding -a onto the command line.

front-end doesn't support SDMA or the latter implements a platform-
specific transfer method instead. While at it, factor out allocation
and freeing of SDMA resources to sdhci_dma_{alloc,free}() in order to
keep the code more readable when adding support for ADMA variants.
o Base the size of the SDMA bounce buffer on MAXPHYS up to the maximum
of 512 KiB instead of using a fixed 4-KiB-buffer. With the default
MAXPHYS of 128 KiB and depending on the controller and medium, this
reduces the number of SDHCI interrupts by a factor of ~16 to ~32 on
sequential reads while an increase of throughput of up to ~84 % was
seen.
Front-ends for broken controllers that only support an SDMA buffer
boundary of a specific size may set SDHCI_QUIRK_BROKEN_SDMA_BOUNDARY
and supply a size via struct sdhci_slot. According to Linux, only
Qualcomm MSM-type SDHCI controllers are affected by this, though.
Requested by: Shreyank Amartya (unconditional bump to 512 KiB)
o Introduce a SDHCI_DEPEND macro for specifying the dependency of the
front-end modules on the sdhci(4) one and bump the module version
of sdhci(4) to 2 via an also newly introduced SDHCI_VERSION in order
to ensure that all components are in sync WRT struct sdhci_slot.
o In sdhci(4):
- Make pointers const were applicable,
- replace a few device_printf(9) calls with slot_printf() for
consistency, and
- sync some local functions with their prototypes WRT static.
- Change short weekday names to use only one Chinese character.
(note: this is a somewhat misunfortunate compromise due to the fact
that some applications are using short buffer for weekday names,
and in ~1905 when 星期 system was created to replace the traditional
七曜 system, which can use 日月火水木金土 to represent Sunday through
Saturday with just one character without any confusion).
- for zh_CN locales: use Arabic numerals for month names, matching the
practice of all other CJK locales
- Regenerate zh_CN.{GB2312,GBK} locales from zh_CN.UTF-8.

the destroying cdev.
Currently linux_destroy_dev() waits for the reference count on the
linux cdev to drain, and each open file hold the reference.
Practically it means that linux_destroy_dev() is blocked until all
userspace processes that have the cdev open, exit. FreeBSD devfs does
not have such problem, because device refcount only prevents freeing
of the cdev memory, and separate 'active methods' counter blocks
destroy_dev() until all threads leave the cdevsw methods. After that,
attempts to enter cdevsw methods are refused with an error.
Implement somewhat similar mechanism for LinuxKPI cdevs. Demote cdev
refcount to only mean a hold on the linux cdev memory. Add sirefs
count to track both number of threads inside the cdev methods, and for
single-bit indicator that cdev is being destroyed. In the later case,
the call is redirected to the dummy cdev.

This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on <limits.h>, which must be stubbed; and a name
change in the Context parameter constants, from ZSTD_p_foo to ZSTD_c_foo.
Significantly, it fixes a kernel build error with GCC where floating-point
functions were included in the kernel build, by hiding them under the same
compile-time #ifdef that already covered their invocation. That issue was
introduced to FreeBSD in the 1.3.7 update and tracked upstream here:

SVN r340744 erroneously changed pfind() to return any process including
zombies and pfind_any() to return only non-zombie processes.
In particular, this caused kill() on a zombie process to fail with [ESRCH].
There is no direct test case for this but /usr/tests/bin/sh/builtins/kill1.0
occasionally triggers it (as reported by lwhsu).
Conversely, returning zombies from pfind() seems likely to violate
invariants and cause panics, but I have not looked at this.
