Hello All,
	As per KK's review comment received on Nov 8 about the free_shared_mem function, Iam sending the following patch.

The change log includes:

1. Break from the main 'for loop' if ba[i] is NULL.

2. In the second level 'for loop', if ba[i][j] is NULL, instead of
continuing as was done previously, we now free the ba[i] pointer and
break from the main 'for loop'.

3. In the 'while loop' inside the second tier 'for loop', if any of the
three pointers (ba or ba->ba_0_org or ba->ba_1_org) is found to be NULL,
then ba[i], ba[i][j] and the non NULL buffer pointer if any
(ba_0_org or ba_1_org) is freed and break from the main 'for loop'.

Oh, bugger...

The recent mmzone.h change triggered some very, very ugly things in
next_zone(), is_highmem(), is_normal() and zone_idx() because it changed
the size of "struct zone" subtly.

Pointer subtraction is no fun when sizeof of object gets weird and poor
gcc blows its brains out trying to optimize that...  This slowed down an
ARM cross-build by a factor of 2.5. 

Turn the pointer subtraction tests into pointer addition tests instead
where possible, making them trivial to deal with (and gets better code,
in addition to faster compile).

zone_idx() still does a subtraction.

Use the existing "tty_sem" to protect against the process tty changes
too.

The isicom driver had bitrotted badly and although it had some 2.6
cleanup work didn't actually do anything useful.  ISIcom had their own
2.4 driver which didn't work with 2.6 either but had done the hard work
like the locking rewrites.  So I nailed them together and then fixed
some obvious bugs in the ISIcom driver version.

This improves pipe throughput, and allows us to (eventually)
use these lists of page buffers for moving data around efficiently.

Clean up swiotlb.c a bit in preparation for some other changes that might be

more uses).  Mostly whitespace and long line fixes, along with a few printk
