fix sparc UP kernels with GCC 4.5, with special thanks to help from
mlelstv@ tracking down the real issue.

sp_tlb_flush() makes various assumptions about the ABI and what GCC
will do with the rest of this function.  the inputs were not referenced
by name but only as "%o0" etc inside the asm.  the result was that GCC
was not filling in the function parameters before calling it because
they were not used in the function.  so, sp_tlb_flush() was getting
random data for it's inputs.  oops.

for now, convert 2 asm() calls to pure C, and mark the inputs for
the sta calls.  this makes GCC generate the right code, but it still
isn't entirely optimal.

ideally a pure C version would exist, but that adds non-trivial
overhead (15 instructions vs 23 or so.)

one more enhancement to make here would be to assign the %o3, %o4 and
%o5 usage into explicit temp variables, instead of assuming that they
are going to be free to use.

(mrg)

Revert previous and fix properly by just removing the #error and a bogus

Add a new ioctl, GPIOPULSE to gpio(4) to allow for pulsing a pin.
If a pin can pulse in hardware, that will be used, else it will
be pulsed in software.  There is no way yet to set the pulse frequency
for pins that pulse in hardware.  While here, make the code mpsafe and
allow more than one thread in the driver (access to ioctl is serialized).

Add some code for grovelling in the PCI configuration space for all
of the memory & I/O space reserved by the PCI BIOS for PCI devices
(including bridges) and recording that information for later use.

The code takes between 13k and 50k (depends on the architecture and,
bizarrely, the kernel configuration) so I am going to move it from
pci_machdep.c into its own module on Monday.

(dyoung)

Replace some anonymous constants with PCI_ constants.

Print debugging information using aprint_debug(9) not aprint_verbose(9)
and be consistent about that.  Get rid of the pciaddrverbose switch for
debugging printfs.

Make 'static' several functions that are private to this module.

Don't test truth of arbitrary integers but compare with 0.  Change
'return (x)' to 'return x'.

(dyoung)

Make the override implementation more concise.  Saves about three lines
of code per routine, makes it more explicit what's going on, and avoids
recursion, though the compiler probably optimized the tail recursion in
the old code.

(dyoung)

In meta mode, we create .meta files for most targets.
These capture all the interesting data - useful for debugging.
In such cases there is no need to replicate commands in the build log.
Rather than run the entire build .SILENT, allow meta mode to set that flag
per target iff a .meta file is created.
Normal behavior is retained for targets where no .meta file is created,
ensuring that no build data is lost.

The loongon2f+cs5526+jmicron PATA->SATA bridge cause an interresting issue:
1) because the CS5536 is not associated with a x86 CPU, interrupts are not
  ack'ed as it expects so interrupts cannot configured as edge-triggered
  (as is expected for a PCIIDE in compat mode)
2) the PATA->SATA bridge ignores the WDC_IDS (interrupt disable bit) so
  the PATA IRQ line gets asserted when resetting or running some polled
  commands. It also wrongly asserts IRQ when the (nonexistent) slave
  device is selected
2) wouldn't be an issue with edge-triggered interrupt because we would
  get a spurious interrupt and continue operation, a new interrupt only shows
  up when the PATA IRQ line goes low and high again. But because of 1),
  we get an unclearable interrupt instead, and the system loops on the
  interrupt handler.

To workaround this, introduce a WDC_NO_IDS compile option which runs
all polled commands (including reset) at splbio() and without sleeps,
so that the controller's interrupt is effectively disabled and
won't be reenabled before the interrupt can be cleared.

The conditions triggering this problem are speficic enough to handle
this via a compile-time option; no need for a run-time (e.g. a
config(9), device property or callback to disable interrupts) solution.

(bouyer)

There are non-writable bits in MIPS_COP_0_TLB_HI between ASID and VPN, so
mips3_cp0_tlb_entry_hi_probe() returns a value with some 0 in the low 12 bits.
Thus the computed mips_vm_maxuser_address is wrong. Fix by oring PAGE_MASK to
return value of mips3_cp0_tlb_entry_hi_probe().

Mark usage as static and dead.

Rename the functions for suspend to reflect that Xen does not hijack
the ACPI "sleepstate" sysctl(7) node anymore.

Add a boolean value to mark that the save/suspend operation has been

Finish and enable whiteout support for tmpfs:

- Enable VOP tmpfs_whiteout().
- Support ISWHITEOUT in tmpfs_alloc_file().
- Support DOWHITEOUT in tmpfs_remove() and tmpfs_rmdir().
- Make rmdir on a directory containing whiteouts working.

Should fix PR #35112 (tmpfs doesn't play well with unionfs).

(hannken)

Rename err() to avoid overlap with libc. Mark it dead.

(joerg)

Add fdisk and ext2fs tools, pmon-based platforms needs them.

(bouyer)

Add loongson support to evbmips, based on the OpenBSD loongson port
and the existing evbmips/gdium support.
This has been tested on a lemote fuloong device (boots multiuser),
should also support other lemote devices (maybe with minor adjustments,
or adding missing drivers). There is some gdium support here too, but it
may not be yet complete (someone with a gdium would need to have a look,
hi macallan@ :)
loongson kernels are 64bits only: the loongson2f has ressources located
above the 2Gb physical address, and it's much easier to access it
using XKPHYS than trying to make it fit in the limited 32bit kernel
virtual space.

(bouyer)

Add pmon (firmware used by loongson2-based systems and maybe others) support,
from OpenBSD.
This includes code to call back pmon routines from a 64bit kernel,
as well code to read pmon arguments and variables.

(bouyer)

Add a basic driver for the SIS315 Pro frame buffer found on some loogson2-based
systems, from OpenBSD.
At this time it can only map the framebuffer and attaches wscons,
using whatever resolution was configured by the firmware.
It doens't support any accelaration or mode change.

(bouyer)

loongson2f support:
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
  instruction (exept when register is k0 or k1) because -mfix-loongson2f-btb
  needs the at register for its workaround
- add code to mips_fixup.c to handle the instructions added by
  -mfix-loongson2f-btb
- Add a ls2-specific tlb miss handler: it doesn't have separate handler
  for the xtlbmiss exeption.
- Fixes for some #ifdef MIPS3_LOONGSON2 assembly code (using the wrong
  register)

(bouyer)

Add a fix-loongson2f-btb option to gas, from OpenBSD.
This works around a bug in the branch prediction logic of the
CPU which can cause a hard hang. The existing fix-loongson2f-jump
works around the same bug, but by 'fixing' the jump target to be within the
same 256MB region as the kernel. This will (silently) cause a jump
to the wrong address if the jump is intentionally to some other
region (e.g. a call to pmon).
fix-loongson2f-btb instead works around the issue by adding an explicit flush
of the branch target buffer (via a write to a cop0 register) before every
jump register instruction.

(bouyer)

Loongson2f support:
- make the 'struct bonito_config' const, so that it can be in kernel
  text instead of data.
- Add a bc_attach_hook to struct bonito_config, to be used as pc_attach_hook
  if not NULL.
- Add some LS2-specific register defines (LS2f uses a modified bonito64).

(bouyer)

add new arp logging sysctls

(christos)

Add 3 logging sysctls for arp from freebsd:

1. log_movements: do you want to log the arp overwritten message or not?
2. log_wrong_iface: do you want to log when an arp arrives at the wrong
  interface?
3. log_permanent_modify: do you want to log when an arp message attempts
  to overwrite a static entry?

I did not call the sysctls log_arp like FreeBSD does, because we already
have an arp sysctl level. The default is on for all three of them.
