default. This has the disadvantage of rendering the datasize resource
limit irrelevant, but without this change, legitimate uses of more
memory than will fit in the data segment are thwarted by default.
Fix chunk_alloc_mmap() to work correctly if initial mapping is not
chunk-aligned and mapping extension fails.
the number of bytes read is actually not important as long as we have at
least what we ask for. Illustrate its benefits by using it throughout
the ZIP support code, except for the few cases where it doesn't apply.

allocation, free the indirect blocks before clearing the disk pointers,
that could lead to the softupdate inconsistencies in the case of the
machine or disk crash at the wrong time.
Rearrange the recover code to do the ffs_blkfree() after the second
ffs_syncvnode(), that clears the pointers chain.

eventually return a negative value for olenp causing sysctl to

set, announce BIO_DELETE capability and issue ATA_CFA_ERASE when we get one.
Once we issue more BIO_DELETE, this will improve lifetime, and
possibly write speed of Flash based devices which have usable flash
adaptation layers.
For now, about the only usage is the newfs(1) -E flag.

peoples code with irrelevant changes[1]:
Use bus_{read|write_*() instead of bus_space_{read|write}_*() for
purely stylistic reasons.
Due to compiler optimizations and inlining, this is for all practical
purposes without effect in the compiled code.

kernel page table page to have a legitimate pindex to support superpage
promotion on kernel memory.
Correct a nearby style error: Pointers should be compared to NULL.
queues lock is acquired. Otherwise, the state of a reservation's
pages' flags and its population count can be inconsistent. That could
result in a page being freed twice.

* Disambiguate version number macros
* Remove unnecessary PACKAGE_NAME macro
* Hook for forthcoming bsdtar test suite
* Sync version number up with the portable distribution

doesn't; it proved useful in bsdcpio as well, so I pushed it down
into libarchive.)
exercises and verifies the libarchive APIs:
* Improved error reporting; hexdumps are now provided for
many file/memory content differences.
* Overall status more clearly counts "tests" and "assertions"
* Reference files can now be stored on disk instead of having
to be compiled into the test program itself. A couple of
tests have been converted to this more natural structure.
* Several memory leaks corrected so that leaks within libarchive
itself can be more easily detected and diagnosed.
* New test: GNU tar compatibility
* New test: Zip compatibility
* New test: Zero-byte writes to a compressed archive entry
* New test: archive_entry_strmode() format verification
* New test: mtree reader
* New test: write/read of large (2G - 1TB) entries to tar archives
(thanks to recent performance work, this test only requires a few seconds)
* New test: detailed format verification of cpio odc and newc writers
* Many minor additions/improvements to existing tests as well.

probably the right thing to do a while ago but xorg has progressed
to the point that for novice users (who are the ones expected to think
installing X11 during an install...) it's best to just install the
whole x11/xorg metaport for them. This removes the X11 sub-menus
and sets it up so you just select whether or not you want X11. While
here garbage collect an X11 configuration menu I missed removing when
I removed support for attempting xorg configuration from inside sysinstall
a while ago.

of two compares against 0. The negative effect of cache flushing
is probably more than the gain by not doing the two compares (the
value is almost certainly in register or at worst, cache).
Note that the uses of m_freem() are in error cases and m_freem()
handles NULL anyhow. So fast-path really isn't changed much at all.
