The UEFI loader causes buildworld to fail when building with (in-tree)
GCC, due to a typedef redefinition. As it happens the in-tree GCC
cannot successfully build the UEFI loader anyhow, as it does not support
__attribute__((ms_abi)). Thus, just avoid trying to build it with GCC, rather than disconnecting it from the build until the underlying issue
is fixed.

Code shamelessly taken in spirit from the radeonkms driver, which I hope will
make this driver redundant in the future.

fts_read() leaves errno unchanged on EOF and sets it on error, so set errno
to 0 before calling it. Also, don't trust finish_execplus() to leave errno
unchanged.
According to <sys/proc.h>, this field needs to be locked with either the
p_mtx or the p_slock. In this case the damage was quite small. Instead
of being reaped, the process would just be reparented to init, so it
could be reaped from there.
While it is the recommended initialization procedure, it hangs on the reset
of the second GPIO module on pandaboard.
Removes the module reset for now as more investigation would be needed.

systems need fine-grained control over what's in and what's out.
That's ideal. For now, separate GPT labels from the rest and allow
g_label to be built with just GPT labels.

These should have been part of r264129, they are part of the overall set
of changes that got several weeks of testing. I must have fumbled them
while merging various patchsets.
correct for the pirbase test (since I'd have thought we'd need to do
something even when the offset is 0 and that test looks like a
misguided attempt to not use an uninitialized variable), but it is at
least the same as today.
CLOCAL and HUPCL control flags. There are legit reasons for allowing
those to be changed. When /etc/ttys has the "3wire" type (without a
baudrate) for the serial port that is the low-level console, then
this change has no effect.

call to freebsd32_convert_msg_in() with freebsd32_copyin_control() to
readin and convert in a single step. This makes it simpler to put all
the control messages in a single mbuf or mbuf cluster as per the
limitations imposed upon us by ip6_setpktopts().
The logic is as follows:
1. Go over the array of control messages to determine overall size
and include extra padding for proper alignment as we go.
2. Get a mbuf or mbuf cluster as needed or fail if the overall
(adjusted) size is larger than a cluster.
3. Go over the array of control messages again, but now copy them
into kernel space and into aligned offsets.
4. Update the length of the control message to take padding between
the header and the data into account (but not for padding added
between one control message and the next).

are unaware of RFC 3542 can construct control messages.
The kernel disallows mixing RFC 2292 behaviour with RFC 3542 behaviour.
Only sockets that have specifically been marked as using the RFC 2292
API can use RFC 2292 specific options. This is all good and well, but
libc itself seems inconsistent with this.
The root cause of this inconsistency seems to relate to the definitions
of IPV6_HOPOPTS and IPV6_DSTOPTS. They are defined in RFC 2292 and re-used
in RFC 3542, yet have distinct values in the kernel. It's for this reason
that the kernel also has definitions for IPV6_2292HOPOPTS and
IPV6_2292DSTOPTS. Not so in libc.
For example: some program calls inet6_option_init() (defined by RFC 2292)
with the RFC 2292 defined IPV6_HOPOPTS and IPV6_DSTOPTS. Before RFC 3542,
this was translated to values of 22 and 23 (resp.) The libc implementation
correctly checks that only options IPV6_HOPOPTS and IPV6_DSTOPTS are given
(as per RFC 2292) but since these defines have taken on the values defined
by RFC 3542 (values 49 and 50 resp,) rejects the correct option values
(22 and 23) passed said program and returns -1.
The precisie fix is to have inet6_option_init() and friends only accept the
RFC 2292 defined IPV6_HOPOPTS & IPV6_DSTOPTS, but that breaks other code
(like mld6query(8)), which seem to not be aware of RFC 3542 and how it
hi-jacked the option names. So the best fix is to accept the options from
both.

On AM335x each one of the four GPIO banks has two physical interrupt
lines, so we now allocate resources and setup our interrupt handler for
all the (8) available interrupts.
On OMAP3 and OMAP4 there is only one interrupt for each GPIO bank (6
banks, 6 interrupts), but there are two set of registers where the
first one is used to setup the delivery of interrupts to the MPU and
the second set, setup the delivery of interrupts to the DSP.
On AM335x, each set of registers controls each one of the interrupt
lines.
- Remove nonexistent registers for OMAP4 and AM335x, replace their use with
the correct ones for these SoCs.
- Remove stray whitespace.
Based on OMAP3, OMAP4 and AM335x TRMs.
Tested on Beaglebone-black.
