The mistake came about like this: the first attempt to commit was blocked by
a pre-commit hook due to missing SVN tags. svn revert doesn't delete new
files, I guess. While reapplying the fixed diff, the non-empty target file
was just concatenated with the new contents? Ugh. :-(

- move allproc lock into the func, it is of no use prior to it
- the code would lock p1 and p2 while holding allproc to partially
construct it after it gets added to the list. instead we can do the
work prior to adding anything.
- protect lastpid with procid_lock
As a side effect we do less work with allproc held.

Code doing this is commented with a claim that these IDs are occupied by
daemons, but that's demonstrably false. To an extent the range is used by init
and kernel processes (and on sufficiently big machines it indeed is fully
populated).
On a sample box 40-way box the highest id in the range is 63. On a different one
it is 23. Just use the range.

Revision 350859 removed level of indirection that was needed for setting the
caller's `cp' pointer. dnsdecode() uses return value to indicate error or
success. It returns pointer to a buffer holding a decompressed DNS name or
NULL. The caller uses that value only to find out the result, not for accessing
the buffer.
We use the return value to propagate the new value of `cp' pointer to
the caller instead of using an output argument.

When local support was fixed, it introduced a minor bug in formatting. We don't
increment the lpos by enouogh, so lines are a little too long. Adjust to be
correct now with variable length srcprefix.
Inizialize global variables earlier in the process. It doesn't matter today, but
may in the future if we want to access these lists earlier in config's run.
Commit message by Jake:
The iflib_register function exists to allocate and setup some common
structures used by both iflib_device_register and iflib_pseudo_register.
There is no associated cleanup function used to undo the steps taken in
this function.
Both iflib_device_deregister and iflib_pseudo_deregister have some of
the necessary steps scattered in their flow. However, most of the
necessary cleanup is not done during the error path of
iflib_device_register and iflib_pseudo_register.
Some examples of missed cleanup include:
the ifp pointer is not free'd during error cleanup
the STATE and CTX locks are not destroyed during error cleanup
the vlan event handlers are not removed during error cleanup
media added to the ifmedia structure is not removed
the kobject reference is never deleted
Additionally, when initializing the kobject class reference counter is
increased even though kobj_init already increases it. This results in
the class never being free'd again because the reference count would
never hit zero even after all driver instances are unloaded.
To aid in proper cleanup, implement an iflib_deregister function that
goes through the reverse steps taken by iflib_register.
Call this function during the error cleanup for iflib_device_register
and iflib_pseudo_register. Additionally call the function in the
iflib_device_deregister and iflib_pseudo_deregister functions near the
end of their flow. This helps reduce code duplication and ensures that
proper steps are taken to cleanup allocations and references in both the
regular and error cleanup flows.

ufsread.c grows a dependency on __ashldi3 with llvm90. For gptboot, just
start pulling in ashldi3.c ashrdi3.c lshrdi3.c into libsa for all archs as
the number of archs requiring one or more of them keeps growing. qdivrem.c
and quad.h can be trivially kicked out of libsa if we start pulling these
from compiler-rt as qdivrem was only used to implement umoddi3, divdi3,

Although libc syscall wrappers do not get checked in this can aid in
finding the source of generated files when spelunking in the objdir.
Multiple tools use @generated to identify generated files (for example,
in a review Phabricator will by default hide diffs in generated files).
For consistency use the @generated tag in makesyscalls.sh as we've done
for other generated files, even though these wrappers aren't checked in
to the tree.
