49b9165251 vm: mmap support
. test74 for mmap functionality
	. vm: add a mem_file memory type that specifies an mmap()ped
	  memory range, backed by a file
	. add fdref, an object that keeps track of FD references within
	  VM per process and so knows how to de-duplicate the use of FD's
	  by various mmap()ped ranges; there can be many more than there can
	  be FD's
	. turned off for now, enable with 'filemap=1' as boot option

33a7ac7557 vfs: mmap support
. libc: add vfs_mmap, a way for vfs to initiate mmap()s.
	  This is a good special case to have as vfs is a slightly
	  different client from regular user processes. It doesn't do it
	  for itself, and has the dev & inode info already so the callback
	  to VFS for the lookup isn't necessary. So it has different info
	  to have to give to VM.
	. libc: also add minix_mmap64() that accepts a 64-bit offset, even
	  though our off_t is still 32 bit now.
	. On exec() time, try to mmap() in the executable if available.
	  (It is not yet available in this commit.)
	. To support mmap(), add do_vm_call that allows VM to lookup
	  (to ino+dev), do i/o from and close FD's on behalf of other
	  processes.

eb1e5bf042 build:arm allow to store build settings in a .settings file.
If present a file called .settings will be sourced when
calling the arm_sdimage.sh script. This allows to configure
the build setting for arm build without the need to specify
the flags each time arm_sdimage.sh is called.

For example to configure arm_sdimage.sh to target the
beaglebone put the following content in your .settings file.

BASE_URL=http://www.minix3.org/arm/beaglebone
FLAG=-DAM335X
CONSOLE=tty00

0d70265775 syslog.conf: correct PID file path in comments.
The syslogd.pid file has moved from /usr/run to /var/run. The comments
in syslog.conf direct the user to restart syslogd using the old PID
file location. This patch updates the comment to match the code.

f0d23d912d servers/pm: Fix EFAULT check for SETGROUPS
The previous test would return EFAULT as soon as the group pointer
was NULL, while it is sensible when the count is also 0.

In that case, the SETGROUP syscall is expected to clear all the
group entries as the new set is empty.

881ff3f6e5 releasetools/arm_sdimage.sh: Improvements
- Added the possibility to define the number of parallel jobs from the
   command line with (example, default is 1):
   $ JOBS=8 ./releasetools/arm_sdimage.sh

 - Generate filesystem filling the reserved partition area, instead of
   being smaller.

 - Added a possibility to specify additional parameter to the build.sh
   script from the command line with (example):
   $ BUILDVARS='-N0 -V MYVAR=yes' ./releasetools/arm_sdimage.sh

154b6d7486 Fix symlink issue when generating an ARM image
A few symlinks were pointing to a nonexistent file named '(null)'
instead of their intended target. This was only seen when using the
arm_sdimage.sh script.

There is two ways of specifying links and directories. the first one
using an entry in one of the mtree files, and the second one in
/etc/Makefile.

Those entries where doubled, and one of them would specify some rights,
while the other had the target.

By removing those entries, I make sure there is only one definition of
these symlinks, which solves the problem I was seeing on an ARM image.

These symlinks are still present on a generated system, as they are
required.

fd5f2edf35 mkfs: only complain about failing stat with -d
mkfs -d is a feature that needs a stat() of the mkfs binary, which
often fails (as mkfs is often not invoked with a full path or from
the same directory). it makes setup look a bit messy as the error
is always printed while installing the system, for each created FS,
even though the situation is harmless. This change only complains
when the stat is actually needed (-d).

d12d57dcd8 arm: recognize instruction fetch pagefault
. an instruction fetch pagefault generates a prefetch

	  a pagefault event
	. the saved_lr argument to the C exception handler was
	  sometimes an address, sometimes a pointer to that address;
	  the kernel sometimes dereferences it, so it should always be
	  an in-kernel address, never a userspace address. fix in mpx.S
	  makes it always a pointer.
