8be8ad916f libedit: add H_SAVE_FP which saves history to a file pointer.
H_SAVE_FP is similar to H_SAVE but operates on a FILE* instead of a filename.
This is useful when operating in capability mode.

still exists but is now silently ignored by the VT core. At least xboxfb

Use of alloca(3) is discouraged in FreeBSD. Using a VLA

b8821f8415 When mapping device memory, use PTE_DEVICE rather than PTE_NOCACHE.
On armv4 these are defined as synonyms right now, but it's a bit ambiguous
what NOCACHE means (is buffering/write-combining also enabled or not?); this
is a first step towards replacing PTE_NOCACHE with a less ambiguous name.

ca5e4fe970 Invalidate the cache for the named posix semaphore when opened and
actual file storing the semaphore object is different from the file
created on the first open.  Store the file st_dev and st_ino members
of the struct stat in the semaphore structure on open, and compare
them with the attributes of the opened file to detect unlink and
re-creation.

This fixes an issue of sem_unlink(3) failing to flush the named entry
in the semaphore list for the current or remote process, making
sem_unlink(3) not correctly operating if the unlinked semaphore is
still opened.

6e76445cf7 sh: Don't discard getopts state on unknown option or missing argument.
When getopts finds an invalid option or a missing option-argument, it should
not reset its state and should set OPTIND as normal. This is an old ash bug
that was fixed long ago in dash. Our behaviour now matches most other
shells.

0973283d6e For the upgrade case in vm_fault_copy_entry(), when the entry does not
need COW and is writeable (i.e. becoming writeable due to the
mprotect(2) operation), do not create a new backing object for the
entry.  The caller of the function is vm_map_protect(), the call is
made to ensure that wired entry has all pages resident and wired in
the top level object and to enable the write.  We might need to copy
read-only page from some backing objects into the top object or remap
the page with the write allowed.

This fixes the issue with mishandling of the swap accounting when
read-only wired mapping is upgraded to write-enabled after fork.  The
previous code path did not accounted the new object, but it creation
is redundand anyway and the change provides an optimization for the
non-common situation.

ee454ea929 Do not configure all pins as outputs as this can lead to short circuits when
the GPIO pin is connected to a push button (or other devices).

Instead keep the boot loader settings.

Calling ar71xx_gpio_pin_configure() with DEFAULT_CAPS was probably a
mistake and was causing all the pins to be set as outputs.

9cce5d9339 Remove an old mistake of mine. This has sneak in the code i sent to gonzo
at that time, but AFAIK it is only used on routerboards.

Enabling GPIO_FUNC_SPI_CS[1|2]_EN will claim the use of gpio pins 0 and 1
respectivelly for use as SPI CS pins.

When really needed, this can still be enabled on kernel hints using the
function_set and function_clear knobs.

dd75f2c5eb Add the lm75 i2c digital temperature sensor driver.
This driver supports the low and high precision models (9 and 11 bits) and
it will auto-detect the both variants.

The driver expose the temperature registers (actual temperature, shutdown
and hysteresys temperature) and also the configuration register.

It was tested on FDT systems: RPi, BBB and on non-FDT systems: AR71xx, with
both, hardware i2c controllers (when available) and gpioiic(4).

This provides a simple and cheap way for verifying the i2c bus on embedded
systems.

ac75ee9fa3 Add in support to optionally pin the swi threads.
Under enough load, the swi's can actually be preempted and migrated
to other currently free cores.  When doing RSS experiments, this lead
to the per-CPU TCP timers not lining up any more with the RX CPU said
flows were ending up on, leading to increased lock contention.

Since there was a little pushback on flipping them on by default,
I've left the default at "don't pin."

The other less obvious problem here is that the default swi
is also the same as the destination swi for CPU #0.  So if one
pins the swi on CPU #0, there's no default floating swi.

A nice future project would be to create a separate swi for
the "default" floating swi, as well as per-CPU swis that are
(optionally) pinned.

Tested:

* parallel TCP tests (2 x 1g unfortunately for now);
  CPU: Intel(R) Xeon(R) CPU E5-2650

Note:

This is based on some initial investigation into RSS/TCP stack lock
contention on FreeBSD-HEAD whilst at Netflix in January 2014.
