Ignoring maxsegsz may lead to fatal data corruption for some devices.
ex. SBP-2/FireWire
We should apply this change to other platforms except for sparc64.

Always set the magic sequence when we write, rather than trusting the
previously read boot code to do so.
Use explicit encoding/decoding of little endian disk image.
Remove a comment which was OBE.
Change the test vector for "fdisk -I" to reflect that there is a magic
sequence in the result now.
Add test case for "fdisk" which reads the image back.
At least for the two test-cases this program now gives the same result
on sparc64 as on i386. The lack of an installed /boot/mbr on sparc64
raises an (un)interesting question.
the cpu dependent files. It will need to be done differently for USIII.
- Simplify the logic for detecting context rollovers. Instead of dealing
with it when the next context switch would cause the context numbers to
rollover, deal with it when they actually do rollover.
- Move some things around in cpu_switch so that we only do 1 membar #Sync
when switching address space, instead of 2.
- Detect kernel threads by comparing the new vm space to vmspace0, instead
if checking if the tlb context is 0.
- Removed some debug code.
This allows us to use them as early as possible while building
bootstrap-, build-, and cross-tools. Some cleanups to follow.
This change resolves the gperf(1) bootstrapping issue (missing
-E option) in gnu/usr.bin/cc/cc1plus while in the cross-tools
stage when upgrading from 4.0-RELEASE.
test is built to test GEOM as running in the kernel.
This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.
the current queue if its priority is really elevated. This needs more work
as there are cases where a next queue kse could be holding up what would
be a curr queue kse, and thus hurting interactivity. Also, when a thread
with an elevated priority has its priority lowered it should be placed
back on the next queue.
legacy stuff (binutils) depend on this order.
For this to work, provide (and use) specialized versions
of bsd.prog.mk and bsd.lib.mk that include the standard
versions first, then augment CFLAGS, DPADD, LDADD, and
LDFLAGS as necessary, with the legacy stuff.
Tested on: 4.0-RELEASE
software section and ports/packages infrastructure section be sect2
level sections (instead of sect3 under userland). Combine the
kernel/contributed and userland/contributed entries into the new sect2
contributed section.
The main point of doing this is that the distinction between kernel
and userland is largely irrelevent for contributed software, and
doesn't apply well to things such as IPFilter and KAME, which have
both kernel and userland components.
