As the uboot disk interface is using common/disk.c API, we also
should use disk_ioctl() call, this will give us chance to read partition
sizes and have feature parity with UEFI and BIOS implementations.
This does also fix arm boot issue on some systems, reported/tested by Ian,
thanks.

The work to make it possible to avoid bcache via using F_NORA modifier did
miss the fact that not all loader platforms are using the bcache, and so
it is possible the modifier is not cleared, as bcache strategy function is
not used.
For fix, we make sure the checks are dont with masked flag.
This patch does fix boot for platforms which do not use bcache.

GDB in ports contains all of the functionality as GDB in base
(including kgdb) for these platforms along with additional

GDB in ports does not currently support kernel debugging on arm,

The smallest device we can have in the pool is 64MB, since we are trying to
walk all four labels to find the most up to date uberblock, this limit will
also give us good method to check if we even should attempt to probe.
Enforcing the check also will make sure we are not getting wrapped while
calculating the label offset.
Also, after label check, we should verify if we actually got any UB or not.

Memory space reserved for pmap_kernel_l2dtable_kva and
pmap_kernel_l2ptp_kva has not been taken into account in
original code. All the memory reserved from kernel space by
pmap_alloc_specials() function called in pmap_bootstrap()
should be mapped initially by initarm(). To create initial
mapping initarm() function reserves proper number of l2 page
tables. However the number of the l2 page tables does not take

pmap_kernel_l2dtable_kva, crashdumpmap, etc.

VM_KMEM_SIZE_MAX allows to limit kmem arena size. In our case this was
necessary, as decreasing size of kmem_arena leaves more space for
kernel_arena.
kernel_arena is pool used for contigmalloc (in effect, DMA) allocations,
which failed on Armada38x. This resulted in 'no memory errors'
(e.g. USB_ERR_NOMEM errors) and failure of whole system. The need for
greater size of kernel_arena probably comes from more peripherals making
use of busdma.
Value used as upper limit is half of the default value
(0x1399a000).

[X86] Remove special handling for 16 bit for A asm constraints.
Our 16 bit support is assembler-only + the terrible hack that is
.code16gcc. Simply using 32 bit registers does the right thing for
the latter.
Fixes PR32681.
This fixes some cases of assembling 16 bit code (i.e. SeaBIOS) that uses

When application reads large directory, calling telldir() for each entry,
like Samba does, it creates exponential performance drop as number of
entries reach tenths to hundreds of thousands. It is caused by full search
through the internal list, that never finds matches in that scenario, but
creates O(n^2) delays. This patch optimizes that search, limiting it to
entries of the same buffer, turning time closer to O(n) in case of linear
directory scan.

in place. To do per-cpu stats, convert all fields that previously were
maintained in the vmmeters that sit in pcpus to counter(9).
- Since some vmmeter stats may be touched at very early stages of boot,
before we have set up UMA and we can do counter_u64_alloc(), provide an
early counter mechanism:
o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter.
o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter,
so that at early stages of boot, before counters are allocated we already
point to a counter that can be safely written to.
o For sparc64 that required a whole dummy pcpu[MAXCPU] array.
Further related changes:
- Don't include vmmeter.h into pcpu.h.
- vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit,
to match kernel representation.
- struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion.

The special case of modifying an existing alias does not work correctly if
the alias is currently in use. Instead, handle this case by unaliasing the
old alias (if any) and then creating a new alias.
Unsign some variables involved in allocation as they will never be
negative anyways. Provide some bounds checking through reallocarray(3).
