193bfa21ea Extend the sample mask from 32 bits to 64 bits.
This is required to support > MCS15 as more than 32 bit rate entries are
suddenly available.

This is quite messy - instead of doing typecasts at each mask operation,
this should be migrated to use a macro and have that do the typecast.

r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

8340ece577 The size of the buffers in an Ethernet freelist has to be higher than the
interface's MTU.  Initialize such freelists with correct values.

This wasn't a problem for common MTUs (1500 and 9000) as the buffers (2048
and 9216 in size) happened to have enough spare room.  I ran into it when
playing around with unusual MTUs.

Make ath_stoptxdma() public, again so the EDMA TX code can use it.

doesn't apply for EDMA.

c64253a898 Rename command defines to match names used in the datasheet, in order to
make maintaining this driver from the documentation easier in the future.
This is a mostly mechanical change.

In uslcom_param(), move the zeroing of the final two fields of the
flowctrl structure outside of the "if CRTSCTS" section - not only were
they being zeroed in both the clauses, but these two fields have nothing
to do with hardware flow control anyway.

- fl_pktshift specifies the padding before Ethernet payload.
- fl_pad specifies the boundary upto which to pad Ethernet payload.
- spg_len controls the length of the status page.

b6d3609050 Add a hackish debugging facility to provide a bit of information about
reason for generated trap. The dump of basic signal information and 8
bytes of the faulting instruction are printed on the controlling
terminal of the process, if the machdep.uprintf_signal syscal is
enabled.

The print is the only practical way to debug traps from a.out
processes I am aware of. Because I have to reimplement it each time I
debug an issue with a.out support on amd64, commit the hack to main
tree.

95fd15898b Real hardware, as opposed to QEMU, does not allow to have a call gate
in long mode which transfers control to 32bit code segment. Unbreak
the lcall $7,$0 implementation on amd64 by putting the 64bit user code
segment' selector into call gate, and execute the 64bit trampoline
which converts the return frame into 32bit format and switches back to
32bit mode for executing int $0x80 trampoline.

Note that all jumps over the hoops are performed in the user mode.

ee4116b8f7 For old mmap syscall, when executing on amd64 or ia64, enforce the
PROT_EXEC if prot is non-zero, process is 32bit and
kern.elf32.i386_read_exec syscal is enabled. This workaround is needed
for old i386 a.out binaries, where dynamic linker did not specified
PROT_EXEC for mapping of the text.

The kern.elf32.i386_read_exec MIB name looks weird for a.out binaries,
but I reused the existing knob which already has the needed semantic.

b6c00483e9 Do not leave invalid pages in the object after the short read for a
network file systems (not only NFS proper). Short reads cause pages
other then the requested one, which were not filled by read response,
to stay invalid.

Change the vm_page_readahead_finish() interface to not take the error
code, but instead to make a decision to free or to (de)activate the
page only by its validity. As result, not requested invalid pages are
freed even if the read RPC indicated success.

06e8730c59 Add locking to the twe(4) driver and make it MPSAFE:
- Add per-controller configuration (sx) and I/O (mutex) locks.  The
  configuration lock protects the relationship of volumes and drives
  while the I/O lock protects access to the controller's registers and
  the main I/O path.
- Remove some checks for M_WAITOK malloc()'s failing.
- Remove the explicit bus space tag/handle from the softc and use
  bus_*() rather than bus_space_*().
- Reuse the existing new-bus sysctl context instead of creating a
  new one.
- Remove compat shims for FreeBSD 4.x.
- Use pci_enable_busmaster() rather than doing it by hand, and rely
  on bus_alloc_resource() to enable PCI I/O decoding.

6e4ac34b07 Remove the deassert INIT IPI from the IPI startup sequence for APs.
It is not listed in the boot sequence in the MP specification (1.4),
and it is explicitly ignored on modern CPUs.  It was only ever required
when bootstrapping systems with external APICs (that is, SMP machines
with 486s), which FreeBSD has never supported (and never will).

While here, tidy some comments and remove some banal ones.

f167c4a762 Port the new PV entry allocator from amd64/i386. This allocator has two
advantages.  First, PV entries are roughly half the size.  Second, this
allocator doesn't access the paging queues, and thus it will allow for the
removal of the page queues lock from this pmap.

Fix a rather serious bug in pmap_remove_write().  After removing write
access from the specified page's first mapping, pmap_remove_write() then
used the wrong "next" pointer.  Consequently, the page's second, third,
etc. mappings were not write protected.
