There are a number of reports of userspace application crashes that
are "solved" by setting vm.pmap.pcid_enabled=0, including Java and the
x11/mate-terminal port (PR ports/184362).
For now apply a band-aid of disabling pcid by default in stable/10.

While it isn't too late and kvm_read_zpcpu() function isn't yet used
outside libkvm(3), change its order of arguments, so that it is the
same as in kvm_read().
Merge r261805 from head:
Add kvm_getncpus() to obtain mp_ncpus.
Remove identical vnet sysctl handlers, and handle CTLFLAG_VNET
in the sysctl_root().
Note: SYSCTL_VNET_* macros can be removed as well. All is
needed to virtualize a sysctl oid is set CTLFLAG_VNET on it.
But for now keep macros in place to avoid large code churn.

This fixes some dereferencing bugs in Chinese character set conversions.
- Fix Simplified Chinese character set conversions by switching around the
fields of an internal struct so it corresponds with the way variables of
this type are initialised.
- Fix an array index out of bounds bug in iconv VIQR (Vietnamese) module.
- Silence gcc warning about unsigned comparison with 0.
Also record r258316 and r258587 as merged so they no longer show up as
eligible.

ext2fs: use of tab vs spaces.
Consistently use a single tab after a #define as mentioned in style(9).
Use tabs instead of space for indenting.
Fix a typo: "hash_vesion".
No functional change.
Document the fact that OpenSSH default configuration requires Capsicum
capability mode support in kernel, which have been worked around later

Add a try-include word (which acts the same as "include") and use it to
conditionally include (but ignore failures) /boot/loader.rc.local and

Extend loader_delay as-documented in beastie.4th(8) and delay.4th(8),
making it available to architectures that do not use or load the beastie
menu. This is reported to save headaches on some PPC systems where unload
followed by load does not produce the desired results wherein if-given
the opportunity to abort the initial loading sequence, you can customize
the first load.

Defer loading of kernel and modules if the beastie menu is enabled. Add a
kernel selection menu to the beastie menu. List of kernels is taken from
`kernels' in loader.conf(5) as a space (or comma) separated list of names
to display (up to 9). If not set, default value is "kernel kernel.old".
Does not validate that kernels exist because the next enhancement will be
to allow selection of the root device.

This is a MFC of r262480 and r262502.
Please note that this is changing a constant in a header file so it
could affect ABIs. However, as far as I can tell, this is apparently
only used in code to declare static arrays and thus it should be safe
to change...

Introduce grab and ungrab upcalls. When the kernel desires to grab the
console, it calls the grab functions. These functions should turn off
the RX interrupts, and any others that interfere. This makes mountroot
prompt work again. If there's more generalized need other than
prompting, many of these routines should be expanded to do those new
things.

ext2fs: fully enable ext4 read-only support.
The ext4 developers tend to tag Ext4-specific flags as
"incompatible" even when such features are not relevant for
read-only support. This is a consequence of the process
though which this filesystem is implemented without design
and the fact that some new features are not extensible to
ext2/3.
Organize the features according to what we support and sort
them so that we can now read-only mount filesystems with
some features that may be found in newly formatted ext4 fs.

malloc_aligned() may not leave enough space for pointer to allocated memory,
saving the pointer will overwrite bytes belongs to another memory block
unexpectly, to fix the problem, use (allocated address + sizeof(void *)) as
initial value, and slip to next aligned address, so maximum extra bytes is
sizeof(void *) + align - 1.

MFC r262334:
Increase alignment to size of pointer if the alignment is too small.
Some modules do not align data at least to size of pointer, they uses a
smaller alignment, but our pointer should be aligned to its native
boundary, otherwise on some platforms, hardware alignment checking
will cause bus error.
