concurrent invocations from acquiring the same address(es). Also, in case
of an incomplete allocation, free any allocated pages.

1st one is relatively minor: according our own manpage, upper and lower
classes must be sorted, but currently not.
2nd one is serious:
tr '[:lower:]' '[:upper:]'
(and vice versa) currently works only if upper and lower classes
have exact the same number of elements. When it is not true, like for
many ISO8859-x locales which have bigger amount of lowercase letters,
tr may do nasty things.
See this page

for detailed description of desired tr behaviour in such cases.
sure that uma_dbg_free() is called if we're about to call
uma_zfree_internal() but we're asking it to skip the dtor and
uma_dbg_free() call itself. So, if we're about to call
uma_zfree_internal() from uma_zfree_arg() and skip == 1, call
uma_dbg_free() ourselves.
frame, occupying scratch registers r16 and up. We don't have to
save any scratch registers for syscalls, so we have plenty of
room there. Consequently, when we fetch the registers from the
process, we automaticly have all the arguments and don't need
to read them seperately.

EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.
We obviously want to do the same when we're booting over the network.
Maybe later.
Based on a patch (from memory) from: arun
there is code that blindly allocates LDTEs starting at slot 6
and I quess it doesn't really matter to us if they overwrite the BSDI
syscall slot, since it isn't a BSDI binary. Also add some code to help track
down other such users (commented out for now).

What is the HPET I hear you ask? It is the High Precision Event Timer
that is supposed to supplement and eventually replace the 8254 timer and
the RTC periodic interrupts. Among other things, it is 64 bit (can be
run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for
the ACPI timer on SMP systems (the specs are much better) and as a
replacement for the ITC based synthetic clock for on ia64 systems.
It seems IA64 and AMD64 systems tend to have this. It is likely to start
showing up in i386 systems if it isn't already on some of them.
that we can flush the register stack prior to entering the kernel.
This avoids having dirty registers and saves us from having to
manually write them to the backing store from within the kernel.
In that respect, flushing the RSE is both functionally required as
well as performance optimal.
On average we had 18 dirty registers when getcontext(2) was called
from libthr. Since libthr does not switch back to a context created
by getcontext(2), not having dealt with the dirty registers was
harmless.
