The main motivation for this change is that only Loris supports
multithreading, and Loris supports dynamic thread allocation, so the
number of supported threads can be implemented as a bit flag (i.e.,
either 1 or "at least as many as VFS has"). The ABI break obviates the
need to support file system versioning at this time, and several
other aspects are better implemented as flags as well. Other changes:
- replace peek/bpeek test upon mount with FS flag as well;
- mark libsffs as 64-bit file size capable;
- remove old (3.2.1) getdents support.

- pass in file system type through mount(2), and return this type in
statvfs structures as generated by [f]statvfs(2);
- align mount flags field with NetBSD's, splitting out service flags
which are not to be passed to VFS;
- remove limitation of mount ABI to 16-byte labels, so that labels
can be made larger in the future;
- introduce new m11 message union type for mount(2) as side effect.

This is a requirement for implementing calls such as getmntinfo(3).
VFS is now responsible for filling in some of the structure's fields.

The following types are modified (old -> new):
* _BSD_USECONDS_T_ int -> unsigned int
* __socklen_t __int32_t -> __uint32_t
* blksize_t uint32_t -> int32_t
* rlim_t uint32_t -> uint64_t
On ARM:
* _BSD_CLOCK_T_ int -> unsigned int
On Intel:
* _BSD_CLOCK_T_ int -> unsigned long
bin/cat is also updated in order to fix warnings.
_BSD_TIMER_T_ has still to be aligned.

Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.
The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.

* port libgpio to am335x.
* increase NR_IRQ to 16 to avoid too many IRQs requested error.
* move gpio binary to /sbin (that's where mount looks for drivers).
* fix bug that re-enabled banks that were disabled due to bad revision.
* fix padconf masks for dm37xx in gpio driver (should be 16-bit).
* fix a few typos in README.txt and comments.

On the AM335X, writes to the padconf registers must be done in privileged
mode. To allow userspace drivers to dynamically change the padconf at
runtime, a kernel call has been added.

Apparently, qemu's sb16 doesn't reset the interrupt register
of the mixer and the driver ends up in an endless loop when
playing a "multi-fragment" sample.

Righ now, the DMA controller will access some random memory below 16 MB,
as the physical address returned by alloc_contig() is simply truncated
when given to the DMA controller.
Yes, it's bad...
. this is OK (although it wastes some memory) as
long as the VM interface isn't used, which has its
own checks in libsys

Previously, all incoming messages would be blocked before a DL_CONF
message arrives from the TCP/IP stack. This however makes it impossible
for a driver to process interrupts before the DL_CONF initialization.
This patch blocks only datalink messages before the initial DL_CONF,
and lets through all other messages to the driver.

The VM server now manages its call masks such that all user processes
share the same call mask. As a result, an update for the call mask of
any user process will apply to all user processes. This is similar to
the privilege infrastructure employed by the kernel, and may serve as
a template for similar fine-grained restrictions in other servers.
Concretely, this patch fixes the problem of "service edit init" not
applying the given VM call mask to user processes started from RC
scripts during system startup.
In addition, this patch makes RS set a proper VM call mask for each
recovery script it spawns.

To do so, a few dependencies have been imported:
* external/bsd/lutok
* external/mit/lua
* external/public-domain/sqlite
* external/public-domain/xz
The Kyua framework is the new generation of ATF (Automated Test
Framework), it is composed of:
* external/bsd/atf
* external/bsd/kyua-atf-compat
* external/bsd/kyua-cli
* external/bsd/kyua-tester
* tests
Kyua/ATF being written in C++, it depends on libstdc++ which is
provided by GCC. As this is not part of the sources, Kyua is only
compiled when the native GCC utils are installed.
To install Kyua do the following:
* In a cross-build enviromnent, add the following to the build.sh
commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes
WARNING:
At this point the import is still experimental, and not supported
on native builds (a.k.a make build).
Change-Id: I26aee23c5bbd2d64adcb7c1beb98fe0d479d7ada
-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm

kernel:
. modules can be as big as the space (8MB) between them
instead of 4MB; memory is slightly bigger with DBG=-g
arm ucontext:
. r4 is clobbered by the restore function, as it's
used as a scratch register, causing problems for the
DBG=-g build
. r1-r3 are safe for scratch registers, as they are
caller-save, so use r3 instead; and don't bother
restoring r1-r3, but preserve r4
