When I moved sparc64 over to HZ==1000 this added some
problems to the udelay() handling.  Specifically, with
slower cpus we could now get underflows to zero for
things like udelay(1) due to the order of multiplies
and shifts.

Fix this, and move it out to arch/sparc64/lib/delay.c
so it is easier to tinker with this in the future and
also to optimize away one of the multiplies for the
constant delay case just like other platforms do.

CAPI skb freeing fix. On sending, the hardware/low-level
driver may free a skb on no error only. The application/core
side must take care otherwise.

Whether a brainfart or a mismerge, I inadvertently broke PA-RISC during
the fork_by_hand()/init_idle() consolidation.

The following patch repairs a compilebug/thinko pair, consisting of the
use of an undeclared variable cpunum, and not attempting fork_idle()
until after the check for IS_ERR(idle) reported by James Bottomley.

chipsets also, a new X 2D + 3D driver are needed to use this but they have
been integrated into at least the X.org tree at this point and I think the
XFree86 tree. There are probably a few cleanups necessary for this driver.

Here is an HVCS (drivers/char/hvcs.c) patch which fixes the hvcs driver
problems with hotplugged vty-server adapters.  The current driver handles
the adapter index assignment improperly so after a number of device
removals and insertions the driver could no longer map a tty->index to a
vty-server properly and tty_open() attempts would fail.  This patch solves
this problem by always assigning the lowest available index to the new
adapters and returning an index to the list when the adapter is removed.

changelog:
drivers/char/hvcs.c
===================
-Added hvcs_index_list to manage the lowest available index.

-Added four helper functions to manage the list, which include the
creation and destruction of the list, the get'ing of the lowest index,
and the returning of an index.

-Moved free_irq() outside of the hvcs_final_close() function in order to
get it out of the spinlock.

-Rearranged hvcs_close() to accomodate the previous change.

-Removed local CLC_LENGTH define and used HVCS_CLC_LENGTH from
arch/ppc64/hvcserver.h instead.

-Cleaned up some printks and did some house keeping on the changelog.

Documentation/powerpc/hvcs.txt
==============================
-Added information on sysfs 'index' attribute added in previous hvcs
patch.

-Added Q & A section on how to find the proper dev node for a newly
added adapter.

I think this is the last of the HVCS patches for a while, as all of my
oustanding issues have been dealt with.

32 bit compatibility code sometimes needs to copy unaligned data across
kernel/user boundary and currently there is no architecture independent API
to do it.

(1) Introduce new APIs __{get,put}_user_unaligned. These APIs are
    necessary because the optimal way to copy unaligned data across
    kernel/user boundary is different on different architectures.
    Some architectures don't even care about alignment.
    On some __put_user is faster than __copy_to_user for small sizes.
(2) Optimize __{get,put}_user_unaligned for ia64, x86-64, s390, ppc64.
(3) Fix compat_filldir64() which is broken on big-endian machines
