363b8ed74f Use callout_init_mtx on FreeBSD versions recent enough. This closes
the race where interrupt thread can complete the request for which
timeout has fired and while mpt_timeout has blocked on mpt_lock.

Do a best effort to keep 4.x ang Giant-locked configurartions
compiling still.

3219f535d9 Rewrite x86bios and update its dependent drivers.
- Do not map entire real mode memory (1MB).  Instead, we map IVT/BDA and
ROM area separately.  Most notably, ROM area is mapped as device memory
(uncacheable) as it should be.  User memory is dynamically allocated and
free'ed with contigmalloc(9) and contigfree(9).  Remove now redundant and
potentially dangerous x86bios_alloc.c.  If this emulator ever grows to
support non-PC hardware, we may implement it with rman(9) later.
- Move all host-specific initializations from x86emu_util.c to x86bios.c and
remove now unnecessary x86emu_util.c.  Currently, non-PC hardware is not
supported.  We may use bus_space(9) later when the KPI is fixed.
- Replace all bzero() calls for emulated registers with more obviously named
x86bios_init_regs().  This function also initializes DS and SS properly.
- Add x86bios_get_intr().  This function checks if the interrupt vector is
available for the platform.  It is not necessary for PC-compatible hardware
but it may be needed later. ;-)
- Do not try turning off monitor if DPMS does not support the state.
- Allocate stable memory for VESA OEM strings instead of just holding
pointers to them.  They may or may not be accessible always.  Fix a memory
leak of video mode table while I am here.
- Add (experimental) BIOS POST call for vesa(4).  This function calls VGA
BIOS POST code from the current VGA option ROM.  Some video controllers
cannot save and restore the state properly even if it is claimed to be
supported.  Usually the symptom is blank display after resuming from suspend
state.  If the video mode does not match the previous mode after restoring,
we try BIOS POST and force the known good initial state.  Some magic was
taken from NetBSD (and it was taken from vbetool, I believe.)
- Add a loader tunable for vgapci(4) to give a hint to dpms(4) and vesa(4)
to identify who owns the VESA BIOS.  This is very useful for multi-display
adapter setup.  By default, the POST video controller is automatically
probed and the tunable "hw.pci.default_vgapci_unit" is set to corresponding
vgapci unit number.  You may override it from loader but it is very unlikely
to be necessary.  Unfortunately only AGP/PCI/PCI-E controllers can be
matched because ISA controller does not have necessary device IDs.
- Fix a long standing bug in state save/restore function.  The state buffer
pointer should be ES:BX, not ES:DI according to VBE 3.0.  If it ever worked,
that's because BX was always zero. :-)
- Clean up register initializations more clearer per VBE 3.0.
- Fix a lot of style issues with vesa(4).

248389c80f Partially revert the change to the gettytab made in r198214.
By misinterpreting some data, I thought that getty wouldn't apply any
baud rate to the syscons devices, but it uses the default entry instead.
This means that the baud rate is set to 1200. This isn't too bad, except
when using canonical mode. Make it use 9600 baud by default.

6015f6f35a Properly set the low watermarks when reducing the baud rate.
Now that buffers are deallocated lazily, we should not use
tty*q_getsize() to obtain the buffer size to calculate the low
watermarks. Doing this may cause the watermark to be placed outside the
typical buffer size.

This caused some regressions after my previous commit to the TTY code,
which allows pseudo-devices to resize the buffers as well.

5ed8d12443 Allow the buffer size to be configured for pseudo-like TTY devices.
Devices that don't implement param() (which means they don't support
hardware parameters such as flow control, baud rate) hardcode the baud
rate to TTYDEF_SPEED. This means the buffer size cannot be configured,
which is a little inconvenient when using canonical mode with big lines
of input, etc.

Make it adjustable, but do clamp it between B50 and B115200 to prevent
awkward buffer sizes. Remove the baud rate assignment from
/etc/gettytab. Trust the kernel to fill in a proper value.

to for the userland. GNU/Linux has moved their default to Medium/Middle

7564c4ad9a If ET_DYN binary has non-zero base address for some reason, honour it
and do not relocate the binary to ET_DYN_LOAD_ADDR. This allows for the
binary author to influence address map of the process. In particular,
when the binary is actually an interpeter, this allows to have almost
usual process address map.

Communicate the relocation bias of the mapping for interpeter-less
ET_DYN binary, that is interperter itself, in AT_BASE aux entry. This
way, rtld is able to find its dynamic structure and relocate itself.
Note that mapbase in the rtld is still wrong and requires further
fixing.

a0585a1450 overhauls urtw(4) for supporting RTL8187B devices properly that there
was major changes to initialize RF chipset and set H/W registers and
removed a lot of magic numbers on code.  Details are as follows:

  - uses the endpoint 0x89 to get TX status information which used to
    get TX complete or retry numbers or get a beacon interrupt.  It's
    only valuable for RTL8187B.
  - removes urtw_write[8|16|32]_i functions that it's useless now.
  - uses ic->ic_updateslot to set SLOT, SIFS, DIES, EIFS, CW_VAL
    registers that doesn't set these whenever the channel is changed.
  - code for initializing RF chipset for RTL8187B changed a lot that
    there was many problems on TX transfers so it doesn't work properly
    even if just for a ping/pong.  Now it becomes more stable than
    before that TX throughputs using netperf(1) were about 15 ~ 17Mbps/s
    though sometimes it encounters packet losses.
  - removes a lot of magic numbers that in the previous all of
    representing RX and TX descriptors were consisted of magic numbers
    and structures.  It'd be more readable rather than before.
  - calculates TX duration more accurately for urtw(4) devices.

12ac99dc46 Close a race with caching of -ve name lookups in the NFS client.
Specifically, clients only trust -ve cache entries while the directory
remains unchanged and discard any -ve cache entries for a directory when
they notice that the modification time of a directory entry changes.  The
race involves two concurrent lookups as follows:
- Thread A does a lookup for file 'foo' which sends a lookup RPC to the
  server.  The lookup fails and the server replies.
- The 'foo' file is created (either by the same client or a different
  client) updating the modification time on the parent directory of 'foo'.
- Thread B does a lookup for a different file 'bar' which updates the
  cached attributes of the parent directory of 'foo' to reflect the new
  modification time after 'foo' was created.
- Thread A finally resumes execution to parse the reply from the NFS
  server.  It adds a -ve cache entry and sets the cached value of the
  directory's modification time that is used for invalidating -ve cached
  lookups to the new modification time set by thread B.

At this point, future lookups of 'foo' will honor the -ve cached entry
until the cached entry is pushed out of the name cache's LRU or the
modification time of the parent directory is changed again by some other
change.  The fix is to read the directory's modification time before
sending the lookup RPC and use that cached modification time when setting
the directory's cached modification time.  Also, we do not add a -ve cache
entry if another thread has added -ve cache entry that set the directory's
cached modification time to a newer value than the value we read before
sending the lookup RPC.
