it's an API between boot2.c and arm_init.S which calls it..

283dfee925 Further cleanup after r285607.
Remove useless release semantic for some stores to it_need.  For
stores where the release is needed, add a comment explaining why.

Fence after the atomic_cmpset() op on the it_need should be acquire
only, release is not needed (see above).  The combination of
atomic_cmpset() + fence_acq() is better expressed there as
atomic_cmpset_acq().

Use atomic_cmpset() for swi' ih_need read and clear.

7059fa6ff8 Add support for two workarounds for known issues booting GPT in legacy mode on some hardware
For Lenovo laptops with buggy bios (x220, t420, t520):
	Write the 0xee entry into the second slot in the pmbr instead of the first

For some Dell and HP models:
	The BIOS gives a warning message when booting in legacy mode from a GPT partitioned disk where the 0xee partition in the pmbr is not flagged active
	For models known to have this problem, mark the pmbr active during installation

Use smbios data to identify machines known to be affected by any of the above, and offer the user the option to apply the workaround

In bsdinstall's ufs auto mode (autopart partition wizard):
	Allow users to select which type of partition table to use
	Keep current defaults: MBR for BIOS, GPT for UEFI
	This allows users to choose GPT for legacy boot if they wish

e7b25f9168 Deselect the sd card before re-selecting it when working around a problem
with some cards that causes them to become deselected after probing for
switch capabilities.  The old workaround fixes the behavior with some cards,
but causes problems with the cards the behave correctly and don't become
deselected.  Forcing a deselect then reselect appears to work correctly
with all cards in initial testing.

b4490c6e93 The si_status field of the siginfo_t, provided by the waitid(2) and
SIGCHLD signal, should keep full 32 bits of the status passed to the
_exit(2).

Split the combined p_xstat of the struct proc into the separate exit
status p_xexit for normal process exit, and signalled termination
information p_xsig.  Kernel-visible macro KW_EXITCODE() reconstructs
old p_xstat from p_xexit and p_xsig.  p_xexit contains complete status
and copied out into si_status.

82a3d2cbfc Add an API for easily creating userspace threads in kernelspace.
This change refactors the existing create_thread() function to be more
generic. It replaces almost all of its arguments by a callback that can
be used to extract the thread ID and copy it out to the right place, but
also to perform additional initialization steps, such as setting the
trapframe. This also makes the difference between thr_new() and
thr_create() more clear in my opinion.

This function is going to be used by the CloudABI compatibility layer.

6e5fcd99df Add a sysentvec for CloudABI on x86-64.
Summary:
For CloudABI we need to put two things on the stack of new processes:
the argument data (a binary blob; not strings) and a startup data
structure. The startup data structure contains interesting things such
as a pointer to the ELF program header, the thread ID of the initial
thread, a stack smashing protection canary, and a pointer to the
argument data.

Fetching system call arguments and setting the return value is similar
to FreeBSD. The only differences are that system call 0 does not exist
and that we call into cloudabi_convert_errno() to convert the error
code. We also need this function in a couple of other places, so we'd
better reuse it here.

a529288d65 Optimise the DWC OTG host mode driver's transmit path:
1) Use the TX FIFO empty interrupts to poll the transmit FIFO usage,
instead of using own software counters and waiting for SOF
interrupts. Assume that enough FIFO space is available to execute one
USB OUT transfer of any kind when the TX FIFO is empty.

2) Use the host channel halted event to asynchronously wait for host
channels to be disabled instead of waiting for SOF interrupts. This
results in less turnaround time for re-using host channels and at the
same time increases the performance.

The network transmit performance measured by "iperf" for the "RPi-B v1
2011/12" board, increased from 45MBit/s to 65Mbit/s after applying the
changes above.

No regressions seen using:
 - High Speed (BULK, CONTROL, INTERRUPT)
 - Full Speed (All transfer types)
 - Low Speed (Control and Interrupt)
