sys/kbio.h: make pre-unicode keymap support optional
FreeBSD-9 had introduced support for the full set of Unicode
characters to the parsing and processing of keymap character tables.
This support has been extended to cover the table for accented
characters that are reached via dead key combinations in FreeBSD-13.2.
New ioctls have been introduced to support both the pre-Unicode and
the Unicode formats and keyboard drivers have been extended to support
those ioctls.
This commit makes the ABI compatibility functions in the kernel
optional and dependent on COMPAT_FREEBSD13 in -CURRENT.
The kbdcontrol command in -CURRENT and 13-STABLE (before 13.2) has
been made ABI compatible with old kernels to allow a new world to be

This commit is not to merged back to 12-STABLE or 13-STABLE. It is

kbdcontrol: enable pre-Unicode dead key table compatibility
The definition of pre-Unicode keymap ioctls will be made optional and

While we generally provide ABI compatibility for older binaries on

Passing the kernel configuration option COMPAT_FREEBSD13 to the build

an upgrade from FreeBSD-8 to FreeBSD-9).
Unicode support for accented characters that are reached via dead key

Suppose that the cluster size is larger than page size. If the buffer

Correct the buffer state by calling vfs_bio_clrbuf() on it, to mark

arm64 pmap: Fix a buffer overrun initializing per-superpage locks.
pmap_init_pv_table makes a first pass over the memory segments to
compute the amount of address space needed to allocate per-superpage
locks. It then makes a second pass over each segment allocating
domain-local memory to back the pages for the locks belonging to each
segment. This second pass rounds each segment's allocation up to a
page size since the domain-local allocation has to be a multiple of
pages. However, the first pass was only doing a single round of the
total page counts up at the end not accounting for the padding present
in each segment. To fix, apply the rounding in each segment in the
first pass instead of just at the end.
While here, tidy the second pass a bit by trimming some
not-quite-right logic copied from amd64. In particular, compute pages
directly at the start of the loop iteration to more closely match the
first loop. Then, drop an always-false condition as 'end' was
computed as 'start + pages' where 'start == highest + 1'. Thus, the
actual condition being tested was 'if (highest >= highest + 1 +
pages)'. Finally, remove 'highest' entirely by keep the result of the
'pvd' increment in the existing loop.
`cpu_data(cpu)` evaluates to a `struct cpuinfo_x86` filled with
attributes of the given CPU number. The CPU number is an index in the
`__cpu_data[]` array with MAXCPU entries. On FreeBSD, we simply
initialize all of them like we do with `boot_cpu_data`.
While here, we add the `x86_model` field to the `struct cpuinfo_x86`. We
use `CPUID_TO_MODEL()` to set it.
At the same time, we fix the value of `x86` which should have been set
to the CPU family. It was using the same implementation as
`CPUID_TO_MODEL()` before. It now uses `CPUID_TO_FAMILY()`.
