1e315c9022 Put back the casts to unsigned. While no strictly necessary for its
current uses, the name strcmp has strong connotations that shouldn't
lightly be discarded.  This doesn't cost us anything.

4b420d501f Add a mutex to struct vm_object. Initialize and destroy that mutex
at appropriate times.  For the moment, the mutex is only used on
the kmem_object.

86fea6be59 o Untangle the confusion with the malloc flags {M_WAITOK, M_NOWAIT} and
the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}.
o Fix a bpf_compat issue where malloc() was defined to just call
  bpf_alloc() and pass the 'canwait' flag(s) along.  It's been changed
  to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
  flag (and only one of those two).

24c9ad6bed - Remove vm_page_sleep_busy(). The transition to vm_page_sleep_if_busy(),
which incorporates page queue and field locking, is complete.
 - Assert that the page queue lock rather than Giant is held in
   vm_page_flag_set().

06d7d664b3 Spell `unsigned short' in a way which does not depend on namespace pollution.
Note that this is still the wrong type, but we are not ready to break the
ABI; this change simply allows programs which specify a strict SUSv3
namespace to compile.  (They may still have semantic errors, since SUSv3
specifies correct types.)

copy the mbuf chain into an mbuf cluster when there is
more than 63 mbufs in the chain.  We were trying with older

1e90b74683 Solve another bug in the mapping code: correctly skip lock sectors.
Make sure sector zero is protected if it contains metadata.

Lower WARNS for gbde to 3 on non-i386 archs.  rijndael-fst is evil
but appearntly does the right thing and passes the test-vectors.

fe6fb873dc Under some circumstances, the loopback interface will allocate a new
mbuf for a packet looping back to provide alignment guarantees for
KAME.  Unfortunately, this code performs a direct copy of the header
rather than using a header copying primitive (largely because we have
sucky header copying primitives).  This results in a multiple free
of the MAC label in the header when the same label data is freed
twice when the two mbufs with that header are freed.  As a temporary
work-around, clear the initialized flag on the label to prevent the
duplicate free, which prevents panics on large unaligned loopback
IP and IPv6 data.  The real fix is to improve and make use of proper
packet header copying routines here.

91c71b46ed Export the physical address of the RSDP to userland by means
of the `machdep.acpi_root' sysctl. This is required on ia64
because the root pointer hardly ever, if at all, lives in the
first MB of memory and also because scanning the first MB of
memory can cause machine checks.
This provides a save and reliable way for ACPI tools to work
with the tables if ACPI support is present in the kernel. On
ia64 ACPI is non-optional.

79cfd4b63b I didn't intend to delete this rm from the Makefile. It snuck in at
the last second before the commit.

# likely we can remove this hack now that gcc generates better aligned code

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.
