On some POWER9 systems, 'reg' denotes the full memory in the system, while
'linux,usable-memory' denotes the usable memory. Some memory is reserved for
NVLink usage, so is partitioned off.

We can't modify vendor code so there's no signal in warnings from it.
Similarly -Waddress-of-packed-member is not useful on networking code
as access to packed structures is fundamental to its operation.
The code is pretty much guaranteed not to be able to unlock.
This is a minor nit. The code still performs way too many reads.
The altered exclusive-locked condition is supposed to be always
true as well, to be cleaned up at a later date.
Of relevance:
o job.c: skip polling job token pipe
o parse.c: be more cautious about detecting depenency line
rather than sysV style include.
also in mk:
* dirdeps.mk: include local.dirdeps-build.mk when .MAKE.LEVEL > 0
ie. we are building something.
* FILES: add dirdeps-options.mk to deal with optional DIRDEPS.
* ldorder.mk: describe how to use LDORDER_EXTERN_BARRIER
if needed.
If a socket is closed or shutdown and a partial record (or what
appears to be a partial record) is waiting in the socket buffer,
discard the partial record and close the connection rather than
waiting forever for the rest of the record.

There are risks associated with waiting on a preemptible epoch section.
Change the name to make them not be the default and document the issue
under CAVEATS.

Such pages are dequeued as they're encountered during the inactive queue
scan, so by the time we get to the active queue scan, they should have
already been subtracted from the inactive queue length.

Microchip provided a permissively-licensed lan78xx header, which has
an 'ETH_' prefix on most definitions. Follow suit in our driver.

Convert pmcannotate to using $TMPDIR and _PATH_TMP rather than hard
coding /tmp for temporary files. Pmcannotate sometimes needs quite a
lot of space to store the output from objdump, and will fail in odd
ways if that output is truncated due to lack of space in /tmp.

match the name of this capability. It was added recently and is not merged
to stable branch, so I hope it is not too late to change the name.

1. align to 128 bytes to avoid possible waste from the preceeding section
2. sort entries by alignment SORT_BY_ALIGNMENT, plugging the holes (most
entries are one byte in size, but they got interleaved with bigger ones)
Interestingly I was looking for a feature of the sort earlier and failed
to find it. It turns out the script was already utilizing sorting in other
places, so shame on me.
Thanks for Travis Geiselbrecht for pointing me at the feature.

- epoch_enter_critical() - can be called inside a different epoch,
starts a section that will acquire any MTX_DEF mutexes or do
anything that might sleep.
- epoch_exit_critical() - corresponding exit call
- epoch_wait_critical() - wait variant that is guaranteed that any
threads in a section are running.
- epoch_global_critical - an epoch_wait_critical safe epoch instance

Since NFSv4.1 clients normally create a single session which supports
both fore and back channels, it is unlikely that a callback will fail
due to a lack of a back channel.
However, if this failure occurred, the session wasn't being dereferenced
and would never be free'd.
Found by inspection during pNFS server development.
