bd34cda61a Bump minor version of config to reflect the new option remapping
feature.  The kernel makefiles have specifically not been bumped
because nothing uses this new feature and doing so forces everybody to
recompile for no good reason.  This chnage will be MFC'd where the
kernel version numbers for amd64 and ia64 will be bumped, since those
are the only two that have use the option remapping feature.  Once
merged, this will give a better error message to folks that are using
buildkernel without buildworld or kernel-toolchain to update their
kernels.

5673e3cb08 The cache_enter(9) function shall not be called for doomed dvp.
Assert this.

In the reported panic, vdestroy() fired the assertion "vp has namecache
for ..", because pseudofs may end up doing cache_enter() with reclaimed
dvp, after dotdot lookup temporary unlocked dvp.
Similar problem exists in ufs_lookup() for "." lookup, when vnode
lock needs to be upgraded.

Verify that dvp is not reclaimed before calling cache_enter().

a318bc273d For the experimental NFS client doing an NFSv4 mount,
set the NFSCLFLAGS_RECVRINPROG while doing recovery from an expired
lease in a manner similar to r206818 for server reboot recovery.
This will prevent the function that acquires stateids for I/O
operations from acquiring out of date stateids during recovery.
Also, fix up mutex locking on the nfsc_flags field.

248bb9379f Fix a deadlock in the shutdown code:
When performing a smp_rendezvous() or more likely, on amd64 and i386,
a smp_tlb_shootdown() the caller will end up with the smp_ipi_mtx
spinlock held, busy-waiting for other CPUs to acknowledge the operation.
As long as CPUs are suspended (via cpu_reset()) between the active mask
read and IPI sending there can be a deadlock where the caller will wait
forever for a dead CPU to acknowledge the operation.
Please note that on CPU0 that is going to be someway heavier because of
the spinlocks being disabled earlier than quitting the machine.

Fix this bug by calling cpu_reset() with the smp_ipi_mtx held.
Note that it is very likely that a saner offline/online CPUs mechanism
will help heavilly in fixing similar cases as it is likely more bugs
of this type may arise in the future.

- Properly initialize and destroy system_taskq.
 - Add a dummy implementation of taskq_create_proc().

Note: We do not currently use system_taskq in ZFS so this is mostly a
no-op at this time.  Proper system_taskq initialization is required
by newer ZFS code.

745bba1ab0 o) Eliminate the "stand" frame and its use. Use CALLFRAME_* everywhere.
o) Use <machine/asm.h> macros for register-width, etc., rather than doing it
   by hand in a few more assembly files.
o) Reduce diffs between various bits of TLB refill code in exception.S and
   between interrupt processing code.
o) Use PTR_* to operate on registers that are pointers (e.g. sp).
o) Add and use a macro, CLEAR_PTE_SWBITS rather than using the
   mysteriously-named WIRED_SHIFT to select bits to truncate when loading PTEs.
o) Don't doubly disable interrupts by moving zero to the status register,
   especially since that has the nasty side-effect of taking us out of 64-bit
   mode.
o) Use CLEAR_STATUS to disable interrupts the first time.
o) Keep SR_PX set as well as SR_[KSU]X when doing exception processing.  This
   is the bit that determines whether 64-bit operations are allowed.
o) Don't enable interrupts until configure_final(), like most other ports.

   can be written through mips_wr_ebase() rather than mips_wr_prid1().

ca596a25f0 o) Add a VM find-space option, VMFS_TLB_ALIGNED_SPACE, which searches the
address space for an address as aligned by the new pmap_align_tlb()
   function, which is for constraints imposed by the TLB. [1]
o) Add a kmem_alloc_nofault_space() function, which acts like
   kmem_alloc_nofault() but allows the caller to specify which find-space
   option to use. [1]
o) Use kmem_alloc_nofault_space() with VMFS_TLB_ALIGNED_SPACE to allocate the
   kernel stack address on MIPS. [1]
o) Make pmap_align_tlb() on MIPS align addresses so that they do not start on
   an odd boundary within the TLB, so that they are suitable for insertion as
   wired entries and do not have to share a TLB entry with another mapping,
   assuming they are appropriately-sized.
o) Eliminate md_realstack now that the kstack will be appropriately-aligned on
   MIPS.
o) Increase the number of guard pages to 2 so that we retain the proper
   alignment of the kstack address.

7ea710b3b1 Avoid extraneous recovery cycles in the experimental NFS client
when an NFSv4 server reboots, by doing two things.
1 - Make the function that acquires a stateid for I/O operations
    block until recovery is complete, so that it doesn't acquire
    out of date stateids.
2 - Only allow a recovery once every 1/2 of a lease duration, since
    the NFSv4 server must provide a recovery grace period of at
    least a lease duration. This should avoid recoveries caused
    by an out of date stateid that was acquired for an I/O op.
    just before a recovery cycle started.
