db726f026b Set RB_SERIAL in boothowto if the firmware output-device is ttya or ttyb.
This ensures that uart gets a higher console priority than syscons when
a serial console is being used.  Testing against the "console" environment
variable doesn't make sense since we only have one loader console driver.

79be2e97e9 Disable probing of HTT CPUs by default for the MP Table case. HTT CPUs
should only be used if they are enabled in the BIOS.  Now that we support
enumerating CPUs using the ACPI MADT, any HTT machine using ACPI should
respect the BIOS setting.  For HTT machines with ACPI disabled in the
kernel, the MPTABLE_FORCE_HTT kernel option can be used to try to probe HTT
CPUs like have done in the past for the MP Table case.  This option should
only be enabled if HTT is enabled in the BIOS.

12457aa888 Save and restore the high FP registers in {g|s}_mcontext(). Note
that we currently do not keep track of whether the thread has
actually used the high FP registers before. If not, we should
not save them in the context which automaticly means that we
also would not restore them from the context. For now, do it
unconditionally so that we can reach functional completeness.

b097722b0b Fix a nasty bug that got exposed when the sendsig() and sigreturn()
functions switched to using {g|s}et_mcontext(). The problem is that
sigreturn(), being a syscall, can be given an async. context (i.e.
one corresponding to an interrupt or trap). When this happens, we
try to return to user mode via epc_syscall_return with a trapframe
that can only be used to return to user mode via exception_restore.

To fix this, we check the frame's flags immediately prior to
epc_syscall_return and branch to exception_restore for non-syscall
frames. Modify the assertion in set_mcontext() to check that if
there's a mismatch, it's because of sigreturn().

47e6302cb2 Fix a bug in the data access error recorvery. Before re-enabling the data
cache after a data access error we must discard all cache lines.  When
disabled existing cache lines are not invalidated by stores to memory, so
we risk reading stale data that was cached before the data access error if
we don't flush them.  This is especially fatal when the memory involved
is the active part of the kernel or user stack.  For good measure we also
flush the instruction cache.

This fixes random crashes when the X server probes the PCI bus through
/dev/pci.

b1d1754bf2 Stop using shared locks for nfs vop locks.
The reason this was done was to avoid a race to the root when an
NFS server went down.  However a semi-recent change to the way that
the kernel's lookup() routine traverses mount points prevents this.

Rev 1.39 of vfs_lookup.c changed the ordering of locks such that we
aquire a shared lock on the mount point being accessed and then drop
the directory vnode lock before requesting the target lock.

With that in place we no longer need shared locks for NFS to prevent
race to the root lockups.

8837bee815 Fix a bug where the taskqueue kproc was being parented by init
because RFNOWAIT was being passed to kproc_create.

The result was that shutdown took quite a bit longer because this
errant "child" would not respond to termination signals from init
at system shutdown.

RFNOWAIT dissassociates itself from the caller by attaching to init
as a parent proc.  We could have had the taskqueue proc listen for
SIGKILL, but being able to SIGKILL a potentially critical system
process doesn't seem like a good idea.

4eec3808af Fixed loss of setting of the RB_BOOTINFO flag in rev.1.43. Fixed wrong
comment about this flag in rev.1.61.  It is not historical like the
comment said; it is the flag that says that most of what is laboriously
put in the bootinfo struct is actually there.  Newer kernels were
bootable by even the broken boot2 without losing anything except the
symbol table, but older kernels need at least the memory sizes.

Restoring the "|" with RB_BOOTINFO that was lost in rev.1.43 costs 5
bytes.  The fix can be done in only 4 bytes by fixing some code that
was removed in rev.1.61 (put RB_BOOTINFO back in in the initial value
of "opts" and fix RBX_MASK to not clobber it.)

3fb83070b6 When there are no free sem_undo structs available in semu_alloc(), only
free one sem_undo with un_cnt == 0 instead of all of them. This is a
temporary workaround until the SLIST_FOREACH_PREVPTR loop gets fixed so
that it doesn't cause cycles in semu_list when removing multiple adjacent
items. It might be easier to just use (doubly-linked) LISTs here instead
of complicated SLIST code to achieve O(1) removals.

This bug manifested itself as a complete lockup under heavy semaphore use
by multiple processes with the SEM_UNDO flag set.
