the description in Documentation/filesystems/proc.txt of the
procs_running entry in /proc/stat is confusing (according to that
description, it looks as if procs_running could only be a number
between 0 and the number of CPUs).
Changed it to a more accurate description in the patch attached.

The bkl has been removed from nvram_llseek() and smp_lock.h was removed
because another patch in the same tree zapped the remaining usage of bkl
in the same file. But this patch must have been excluded later, then we
still need the smp_lock.h headers for the bkl use in nvram_open().
This fixes the following build error:
drivers/char/nvram.c: In function ‘nvram_open’:
drivers/char/nvram.c:332: erreur: implicit declaration of function ‘lock_kernel’

This reverts commit f20941f334.
Sergei Shtylyov notes "You call min() on uncomparables [in
mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and
adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second
argument will always "win" as a minimal one"
Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related
to mwdma_clip_to_pio(). The function can return values between 0 and
4 which obviously won't work well for the new code below for values
>2 (i.e. resulting in out-of-bounds array access for the common-case
of dev->pio_mode == XFER_PIO_4)."
Bartlomiej Zolnierkiewicz also notes the patch is incomplete, failing to
update MWDMA mode masks.
