build-sys: missing header when NLS is disabled
Compiling utils fail when disable NLS with the --disable-nls switch.
"mkfs.c:46: error: 'LC_ALL' undeclared (first use in this function)"
It is due to a missing locale.h header : When enabling NLS, nls.h
includes libintl.h, which in turn includes locale.h. When disabling NLS,
libintl.h isn't anymore included nor locale.h, which is needed for the
setlocale() calls.

fdisk: check returns in fdisk from partition changes
currently the code in fdisk which changes partition types is a bit fragile ...
it assumes the partition type succeeded instead of checking the user input or

The arch command is deprecated in favor of "uname -m" (coreutils). The

to "uname -a". Please, if you need arch(1) use the coreutils
implementation.

lomount.c: don't use mlockall if CRYPT_NONE
loop back mounting emits two system calls: mount and mlockall.
mount is obviously needed. mlockall is needed for encryption.
As the result both CAP_SYS_ADMIN and CAP_IPC_LOCK are needed
to do loopback mounting.
The problem is that CAP_IPC_LOCK is always needed through my
command doesn't need encryption.
With the following patch, mount calls mlockall only when
encryption is needed.

fdisk: many significant improvements and fixes to Sun label handling
1) Properly describe the exact layout and fields of the sun disk
label. Several fields were incorrectly mentioned and others
wrongly sized.
2) Properly set the version, sane, and num_partitions fields.
Because we weren't doing this, programs such as Solaris's format
and the Solaris kernel itself refused to recognize our disk labels
as valid.
3) Move SSWAP*() macros into fdisksunlabel.c as there is no reason
for them to be exposed to the rest of fdisk.
4) Kill the sun_predefined_drives array hack and assosciated code.
Instead size the disk and figure out the geometry properly just
like the SGI and MSDOS partition handling do, by means of the
HD_GETGEO ioctl() and disksize().
5) If the disk label read is found to not have the proper values
set in version, sane, or num_partitions, fix them, recompute the
label checksum, dirty the disk label, and let the user know what
we did and that the fixed values will be written out if they 'w'.
This gives users an easy way to fix up disk labels created by
disk labelling programs which had this bug.
6) Create a sun_sys_getid() function so that fdisk.c does not need
to reference the sun disk label details directly, just like the
SGI code does.

blockdev: add BLKFRAGET/BLKFRASET ioctls
In Linux 2.6 the BLKRASET ioctl has the desired effect for mounted

read-ahead on the *device* as opposed to within a *file*, and the
maximum value of this number is 255. As a result the invocation of
blockdev will fail on Linux 2.4 for any usefully large value of
READAHEAD, and will not in any case have the desired affect for
fragmented files.

taskset: independent of hardcoded NR_CPUS max.
This patch makes the taskset command independent of the system's maximum
number of cpus (CONFIG_NR_CPUS). The maximum for CONFIG_NR_CPUS is a
moving target.
With this patch the size of the systems's cpumask_t is gotten from
sched_getaffinity(2).
This patch uses variable length bitmasks borrowed from Paul Jackson's
variable size bitmask routines (hence I kept his copyright notice).
This replaces the use of the glibc CPU_SETSIZE, CPU_SET, CPU_ZERO and
CPU_ISSET macros which depend on a hardcoded size for cpu_set_t.
(also fixes one little nit: the -V option is "-v" in the built-in help, so
changed the built-in help)

The losetup provides an -f option to discover an unused loop device. As
