- remove unnessisary check that would prevent it from mounting newer nilfs
images. A field has been added in the segment summary.
- store blocks of files on their virtual block number
- VOP_LOCK(vp, flags): Limit the set of allowed flags to LK_EXCLUSIVE,
LK_SHARED and LK_NOWAIT. LK_INTERLOCK is no longer allowed as it
makes no sense here.
- VOP_ISLOCKED(vp): Remove the for some time unused return value
LK_EXCLOTHER. Mark this operation as "diagnostic only".
Making a lock decision based on this operation is no longer allowed.
Discussed on tech-kern.
in ubc_fault(), rework logic to "remember" the last object of page and
reduce locking overhead, since in common case pages belong to one and
the same UVM object (but not always, therefore add a comment).
Unlocks before pmap_update(), on removal of mappings, might cause TLB
coherency issues, since on architectures like x86 and mips64 invalidation
IPIs are deferred to pmap_update(). Hence, VA space might be globally
visible before IPIs are sent or while they are still in-flight.

accounting. Use wired memory (which can be limited) for meta-data, and
kmem(9) for string allocations.
Close PR/31944. Fix PR/38361 while here. OK ad@.
during the mips64 merge. This gets my sbmips kernel booting to the
login prompt. This code could not possibly have been tested after
the merge.
Should fix PR port-mips/43431.
our window to it. This fixes cases like opening a window at offsets
[8,32] to a file, which would cause host file offset [0,32-8] to
be mapped, i.e. [0,16] inside the window. Obviously, access to
the entire in-window [0,24] range should have been mapped (and
after this fix it is).
building X11 without inet6 support. the support to maintain patches to
generated files and other files is too great. PR#42856
- add TOOL_PIGZ, which defaults to the (not yet default) built tools/pigz.
