This patch solve a bug triggered by execvp (this function use calloc to
store the argument list and gcc 3.4.x align the stack to word, not to dword).
This situation aren't related to signal handling and all 2.6.x have the bug.
On ColdFire targets we must force the stack to be aligned.

Bitmap functions for the minix filesystem and the ext2 filesystem except
ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic

We're starting a number of big applications (memory footprint app.
1MByte) on our Arcturus uC5272. Therefore memory fragmentation is a
real pain for us. We've switched to uClinux-2.4.27-uc1 and found that
page_alloc2 fragments the memory heavily.
Digging into it we found a bug in the find_next_zero_bit function in the
m68knommu/bitops.h file. if the size isn't a multiple of 32 than the
upper bits of the last word to be searched should be masked. But the
functions masks the lower bits of the last word because it uses a right
shift instead of a left shift operator.

Several counters already have the need to use 64 atomic variables on 64 bit
platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall
back to 32 bit atomic on 32 bit platforms.
The VM statistics patch that I am working on will also make more extensive
use of atomic64.
This patch introduces a new type atomic_long_t by providing definitions in
asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits
on 32 bit platforms and 64 bits on 64 bit platforms.
Also cleans up the determination of the mm_counter_t in sched.h.
