ppc64 uses its own range allocator for ioremap (in order to allocate
things in a different space than normal vmalloc).  This is historic stuff,
we may get rid of it, but in the meantime, here's a patch turning the
spinlock in there into a semaphore so it doesn't blow up when doing
kmallocs.

This moves the sg_dma_* macros to asm/scatterlist.h where they belong (and
where almost every other architecture has them).

Use the new kallsyms_lookup_name() in xmon on ppc64.  Ben said he might
backport these changes to ppc32 as well.

From: Rusty Russell <rusty@au1.ibm.com>

Attached patch adds a kallsyms_lookupname() function for lookups of a
symbol name to an address.  Debuggers such as ppc[64] xmon can use this.

It's intentionally not exported as a symbol for module use, since it
can be used to circumvent other symbol export restrictions.

Add the PPC64 iSeries virtual disk driver

into ppc970.osdl.org:/home/torvalds/v2.5/linux

This helps avoid doing push/pop pairs on register contents that we just
don't care about. After we've done the xor, the pointers are dead anyway.

into ppc970.osdl.org:/home/torvalds/v2.5/linux

into kernel.bkbits.net:/home/davem/net-2.6

Since we do push/pops, a stack-based memory argument would
do the wrong thing by using the wrong offsets.

The x86-64 implementation of csum-partial.c causes it to compute the
checksum incorrectly.

As a result, multicast doesn't work.  It looks as though iptables is
also affected.

Here's a simple patch.

This patch is the first of several planned fixes for the cyclades
multiserial cards driver.

Its mostly a sync with in-house driver:

- Prevent users from opening non-existing Z ports
- Implement special XON/XOFF character handling in Z cards
- Prevent data-loss on Z cards
- Throttling fix for Z card
- Only throttle if CTS/RTS are set
- Fix accounting of received data

Kudos to Cyclades R&D

PRD_ENTRIES is specified to be precisely 256; on platforms where
PAGE_SIZE varies from 4KB the calculation in the current expression
defining it is inaccurate, which may cause crashes. This patch changes
it to the constant literal 256.

From: Andrew Morton <akpm@osdl.org>

Use sector_t for the block number.

Noticed by Marcel Cotta <mc123@mail.ru>.

ide_init() always initializes system_bus_speed variable
so system_bus_clock() should never call ide_system_bus_speed()
and no driver is calling ide_system_bus_speed() directly.

Bug was that if no IDE kernel parameter was given during boot
system_bus_speed will be zeroed in init_ide_data().

This patch should fix the problem
(as a bonus -> no need to zero these variables they are static).

Add UDMA6 support to ALi PCI IDE driver.
Forward port from 2.4 and a patch from ALi.
