- Increase the granularity of the vm object locking in vm_hold_load_pages()
in order to reduce the number of times that we acquire and release the
same lock.
Fix to the messages output under CAM_DEBUG_CCB: the summary sense
information (error bits and sense key) is in the error field, not
in the result field, of struct ata_request. No other functional change.
completion of recovery is indicated by positioning the CAM_AUTOSNS_VALID
bit in the status field of the CCB, not in the flags field.
This fixes an endless loop of sense recovery actions.

function, startup_alloc(), that is used for single page allocations prior
to the VM starting up. If it is used after the VM startups up, it
replaces the zone's allocf pointer with either page_alloc() or
uma_small_alloc() where appropriate.

device to access 64-bit addresses from a 32-bit PCI bus. While the
RealTek manual says you can set this bit and the chip will perform
DAC only if you give it a DMA address with any of the upper 32
bits set, this appears not to be the case. If I turn on the DAC
bit, the chip sets the 'system error' bit in the status register
when I to do a DMA on my Athlon test box with 32-bit PCI bus (VIA
chipset) even though I only have 128MB of physical memory, and thus
can never give the chip a 64-bit address.
Obviously, I can't just set it and forget it, so until I figure
out the right rule for when it's safe/necessary to enable it, keep
it turned off.
not guaranteed that the RSE writes the NaT collection immediately,
sort of atomically, to the backing store when it writes the register
immediately prior to the NaT collection point. This means that we
cannot assume that the low 9 bits of the backingstore pointer do not
point to the NaT collection. This is rather a surprise and I don't
know at this time if it's a bug in the Merced or that it's actually
a valid condition of the architecture. A quick scan over the sources
does not indicate that we depend on the false assumption elsewhere,
but it's something to keep in mind.
The fix is to write the saved contents of the ar.rnat register to
the backingstore prior to entering the loop that copies the dirty
registers from the kernel stack to the user stack.
functions reference UMA internals from <vm/uma_int.h>, which makes
them highly unwanted in non-UMA specific files.

Doing so creates a race where the buf is on neither list.
- Only vfree() in an error case in vclean() if VSHOULDFREE() thinks we
should.
- Convert the error case in vclean() to INVARIANTS from DIAGNOSTIC as this
really should not happen and is fast to check.
sufficient to guarantee that this race is not hit. The XLOCK will likely
have to be redesigned due to the way reference counting and mutexes work
in FreeBSD. We currently can not be guaranteed that xlock was not set
and cleared while we were blocked on the interlock while waiting to check
for XLOCK. This would lead us to reference a vnode which was not the
vnode we requested.
- Add a backtrace() call inside of INVARIANTS in the hopes of finding out if
this condition is ever hit. It should not, since we should be retaining
a reference to the vnode in these cases. The reference would be sufficient
to block recycling.
working set cache. This has several advantages. Firstly, we never touch
the per cpu queues now in the timeout handler. This removes one more
reason for having per cpu locks. Secondly, it reduces the size of the zone
by 8 bytes, bringing it under 200 bytes for a single proc x86 box. This
tidies up other logic as well.
- The 'destroy' flag no longer needs to be passed to zone_drain() since it
always frees everything in the zone's slabs.
- cache_drain() is now only called from zone_dtor() and so it destroys by
default. It also does not need the destroy parameter now.
broken consumers of the malloc interface who assume that the allocated
address will be an even multiple of the size.
- Remove disabled time delay code on uma_reclaim(). The comment there said
it all. It was not an effective strategy and it should not be left in
#if 0'd for all eternity.
restart instruction bits in the PSR. As such, we were returning
from interrupt to the instruction in the bundle that caused us
to enter the kernel, only now we're returning to a completely
different bundle.
While close here: add two KASSERTs to make sure that we restore
sync contexts only when entered the kernel through a syscall and
restore an async context only when entered the kernel through an
interrupt, trap or fault.
While not exactly here, but close enough: use suword64() when we
copy the dirty registers from the kernel stack to the user stack.
The code was intended to be be replaced shortly after being added,
but that was a couple of weeks ago. I might as well avoid that it
is a source for panics until it's replaced.
can get (or not) and what we do with them. This fixes the behaviour
for NaT consumption and speculation faults in that we now don't panic
for user faults.
Remove the dopanic label and move the code to a function. This makes
it easier in the simulator to set a breakpoint.
While here, remove the special handling of the old break-based syscall
path and move it to where we handle the break vector. While here,
reserve a new break immediate for KSE. We currently use the old break-
based syscall to deal with restoring async contexts. However, it has
the side-effect of also setting the signal mask and callong ast() on
the way out. The new break immediate simply restores the context and
returns without calling ast().
