Fix build errors introduced by r367417 and r367390:
- Guard label reached only by powerpc64
- Guard vm_reserv_level_iffullpop call, that is not defined on powerpc
variants that don't support superpages
- Add missing hwpmc file, for when hwpmc is built into kernel
- Rename cse*() to cse_*() to more closely match other local APIs in
this file.
- Merge the old csecreate() into cryptodev_create_session() and rename
the new function to cse_create().

r376026 added a new "-R" option to mountd, which tells it to
not support the Mount protocol (not used by NFSv4) and not
register with rpcbind.
Rpcbind is considered a security issue by some sites now.
This patch adds a new yes/no variable called nfsv4_server_only.
When that is set, make vfs.nfsd.server_min_vers=4 and set "=R"
for mountd.
Setting vfs.nfsd.server_min_vers=4 tells nfsd to not register with rpcbind.
While here, add a check for "load_kld nfsd" failing to nfsd.

This change adds support for transparent superpages for PowerPC64
systems using Hashed Page Tables (HPT). All pmap operations are
supported.
The changes were inspired by RISC-V implementation of superpages,
by @markj (r344106), but heavily adapted to fit PPC64 HPT architecture
and existing MMU OEA64 code.
While these changes are not better tested, superpages support is disabled by
default. To enable it, use vm.pmap.superpages_enabled=1.
In this initial implementation, when superpages are disabled, system
performance stays at the same level as without these changes. When
superpages are enabled, buildworld time increases a bit (~2%). However,
for workloads that put a heavy pressure on the TLB the performance boost
is much bigger (see HPC Challenge and pgbench on D25237).

OCF drivers in general should perform as many session parameter checks
as possible during probesession rather than when creating a new
session. I got this wrong for aesni(4) in r359374. In addition,
aesni(4) was performing the check for digest-only requests and failing

This ensures that no writes are pending in memory, either metadata or

Note that this does not guarantee absence of the metadata errors or

PowerPC kernel is of DYN type and it has a base address where it is
initially loaded, before being relocated. As the start address passed to
pmcstat_image_link() is where the kernel was relocated to, but the symbols
always use the original base address, we need to subtract it to get the
correct offset.

The 2 provided zones had inconsistent naming between each other
("int" and "64") and other allocator zones (which use bytes).
Follow malloc by naming them "pcpu-" + size in bytes.
This is a step towards replacing ad-hoc per-cpu zones with
general slabs.
And add a _74XX suffix to 74XX SPRs.
This is a preparation for adding support to POWER8/9 PMCs, which have most
SPRs equal to 970 ones.

On a sample box vmstat -z shows:
ITEM SIZE LIMIT USED FREE REQ
64: 64, 0, 1043784, 4367538,3698187229
selfd: 64, 0, 1520, 13726,182729008
But at the same time:
vm.uma.selfd.keg.domain.1.pages: 121
vm.uma.selfd.keg.domain.0.pages: 121
Thus 242 pages got pulled even though the malloc zone would likely accomodate
the load without using extra memory.
Memory allocated by bus_dmamem_alloc will take into account any alignment
requirements of the CPU it's running on. Stop trying to bounce in this case
as there is no bounce zone allocated.

Add a pseudofs node flag 'PFS_AUTODRAIN', which automatically emits sbuf
contents to the caller when the sbuf buffer fills. This is only
permissible if the corresponding PFS node fill function can sleep
whenever it appends to the sbuf.
linprocfs' /proc/self/maps node happens to meet this requirement.
Streaming out the file as it is composed avoids truncating the output
and also avoids preallocating a very large buffer.

- Removed a bunch of redundant headers
- Don't explicitly initialize to 0
- The !error check prior to setting imgp->interpreter_name is redundant, all
error paths should and do return or go to 'done'. We have larger problems
otherwise.
lz4 port from illumos to Linux added a 16KB per-CPU cache to accommodate for
the missing 16KB malloc. FreeBSD supports this size, making the extra cache
harmful as it can't share buckets.
In pmap_bootstrap(), we fill kernel_pmap->pm_active since it is
invariably active on all harts. However, this marks it as active even
for harts that don't exist in the system, which can cause issue when the
mask is passed to the SBI firmware via sbi_remote_sfence_vma().
Specifically, the SBI spec allows SBI_ERR_INVALID_PARAM to be returned
when an invalid hart is set in the mask.
The latest version of OpenSBI does not have this issue, but v0.6 does,
and this is triggering a recently added KASSERT in CI. Switch to only
setting bits in pm_active for harts that enter the system.

Linux allows polling without any events specified and it happens to be the case
in FreeBSD as well. POLLHUP has to be delivered regardless of the event mask
and this works fine if the condition is already present. However, if it is
missing, selrecord is only called if the eventmask has relevant bits set. This
in particular leads to a conditon where pipe_poll can return 0 events and
neglect to selrecord, while kern_poll takes it as an indication it has to go to
sleep, but then there is nobody to wake it up.
While the problem seems systemic to *_poll handlers the least we can do is fix
it up for pipes.
