This allows clients to open a file once and "load" it multiple times (e.g.
first with COUNT_KERNEL, then with LOAD_KERNEL) without the side-effects
of multiple open calls.
check is inside the simple_lock()/simple_unlock() pair, so move the locks

Additionally, change the #ifdef from DIAGNOSTIC to DEBUG; the condition
is too weird to be worth checking at DIAGNOSTIC, according ot Jason.

No real functional change (in the produced asm a few condition codes changed)
means that the dynamic linker gets mapped in at the top of available
user virtual memory (typically just below the stack), shared libraries
get mapped downwards from that point, and calls to mmap() that don't
specify a preferred address will get mapped in below those.
This means that the heap and the mmap()ed allocations will grow
towards each other, allowing one or the other to grow larger than
before. Previously, the heap was limited to MAXDSIZ by the placement
of the dynamic linker (and the process's rlimits) and the space
available to mmap was hobbled by this reservation.
This is currently only enabled via an *option* for the i386 platform
(though other platforms are expected to follow). Add "options
USE_TOPDOWN_VM" to your kernel config file, rerun config, and rebuild
your kernel to take advantage of this.
Note that the pmap_prefer() interface has not yet been modified to
play nicely with this, so those platforms require a bit more work
(most notably the sparc) before they can use this new memory
arrangement.
This change also introduces a VM_DEFAULT_ADDRESS() macro that picks
the appropriate default address based on the size of the allocation or
the size of the process's text segment accordingly. Several drivers
and the SYSV SHM address assignment were changed to use this instead
of each one picking their own "default".
as bus_dmamem_alloc_range() is missing we use the ISA dma tag on i386.
The iorange for the dma registers now gets allocated near the used range.
Chances are high, that this range is valid on this PCI bus.
This one is really ugly :-)

(there are still some details to work out) but expect that to go
away soon. To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:
* Create a writer daemon kernel thread whose purpose is to handle page
writes for the pagedaemon, but which also takes over some of the
functions of lfs_check(). This thread is started the first time an
LFS is mounted.
* Add a "flags" parameter to GOP_SIZE. Current values are
GOP_SIZE_READ, meaning that the call should return the size of the
in-core version of the file, and GOP_SIZE_WRITE, meaning that it
should return the on-disk size. One of GOP_SIZE_READ or
GOP_SIZE_WRITE must be specified.
* Instead of using malloc(...M_WAITOK) for everything, reserve enough
resources to get by and use malloc(...M_NOWAIT), using the reserves if
necessary. Use the pool subsystem for structures small enough that
this is feasible. This also obsoletes LFS_THROTTLE.
And a few that are not strictly necessary:
* Moves the LFS inode extensions off onto a separately allocated
structure; getting closer to LFS as an LKM. "Welcome to 1.6O."
* Unified GOP_ALLOC between FFS and LFS.
* Update LFS copyright headers to correct values.
* Actually cast to unsigned in lfs_shellsort, like the comment says.
* Keep track of which segments were empty before the previous
checkpoint; any segments that pass two checkpoints both dirty and
empty can be summarily cleaned. Do this. Right now lfs_segclean
still works, but this should be turned into an effectless
compatibility syscall.
sa_switch() invocations while exiting. Test P_SA instead of L_SA, out

no need device ixpcom in evbarm/conf/files.evbarm move it to
arm/ixp12x0/files.ixp12x0
ixp12x0_com.c:
some fix around address handling
1. Do not call bus_space_map() in ixpcominit(). Calling bus_space_map()
is not safe here, because bus_space_map() calls uvm_km_valloc() but
uvm is not yet initialized.
2. Use dv_unit to determine console instead comparering iobase.
Now you can attach ixpcom0 with physical address like this:
ixpcom* at ixpsip? addr 0x90000000 size 0x4000
Statically mapped address (0xf0000000) is still usable.
ixp12x0_clk:
1. access PLL_CFG register via bus_space
2. Make the delay() working correctly. (bug fix)
3. Start the timer device without interrupt on attach time.
Now delay() called before cpu_initclocks() works fine.
ixp12x0_pci:
1.Mapping PCI type0/1 configuration space to the upper address.
2."PCI I/O Cycle Access" mapping to same virtual address(VA==PA)
but size of this mapping increase to 1MByte because fails
cause couldnt set L2 table.
3.use bus_space address handling in ixp12x0_pci.c.
- make sure that the driver checks the battery presence at acpibat_update()
if the battery has been not present, because the driver sometimes

I misunderstood about ACPI_NOTIFY_BatteryStatusChanged event.

Darwin specific files. The handler does nothing yet.
This needs some improvement. Darwin attaches an IOHIDSystem device to
each human-interface device in the tree: mouse, keyboard, and a few others.
For now we only emulate one IOHIDSystem device.

It will never get back... it will not be found in nfs_nget, a new
nfsnode+vnode is allocated instead, which causes a node leak, and
also makes the mountpointness of the vnode to be forgotten, breaking
filesystem crossing lookups through this vnode.

Dumping from sparsely populated amaps could cause faults that would
result in amaps being split, which (in turn) resulted in the core
dumping routines dumping some regions of memory twice. This makes the
core file too large, the headers not match, gdb not work properly,
and so on.

acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),

Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.

Also, since the changes are pretty invasive, there little point in keeping

This doesn't actually solve the actual problem, which appears to be a race

Modify jazz_bus_dmamap_create() to allocate jazz dmatlb
if BUS_DMA_ALLOCNOW flag is specified and nsegment is 1.
In this case, jazz_bus_dmamap_load() just call
jazz_dmatlb_map_va() to map CPU VA space into jazzio
VA space with pre-allocated TLB entries (like dma.c does).
bus_dmamap_load_{mbuf,uio,raw} functions are not allowed
if dmamap is created with BUS_DMA_ALLOCNOW flag.
