Remove unused 'done_late' arg to ata_qc_complete(), which was never
useful in 2.4, and never used at all in 2.6.

This allows us to eliminate the same arg from ata_dma_complete(),
and also make it more correct by passing the command rather than
the ATA port structure as arg0.

x86_64 has an incorrect ffs() implementation.  The asm uses "g" instead
of "rm" for the bsfl instruction.  (This was spotted by Yuri Per.)

bsfl does not accept constant values but only memory or register ones.
On i386 the correct "rm" is used.

This causes NTFS build to fail as gcc optimizes a variable into a
constant and ffs() then fails to assemble.

this trivial fix makes the AVM B1 PCMCIA cards work with 2.6

This adds links to the driver and device inside /sys/class/net/ethX for
PowerPC Virtual Ethernet devices.

This fixes a bug where different partitions were assigned the same MAC
address.  Also, according to Anton, gcc 3.5 didn't like our mac_addr_p
gymnastics, so this ends up fixing that as well.

It is possible to attach a virtual disk to a logical partition on an iSeries
machine so that it is read only to the partition.  This patch allows Linux to
use such virtual disks.

After I sent the recent patch to include/asm-ppc64/io.h which put stronger
barriers in the I/O accessor macros, Paul McKenney pointed out to me that a
writex/outx could still slide out from inside a spinlocked region.  This patch
makes the barriers a bit stronger so that this can't happen.  It means that we
need to use a sync instruction for wmb (a full "heavyweight" sync), since
drivers rely on wmb for ordering between writes to system memory and writes to
a device.

I have left smb_wmb() as a lighter-weight barrier that orders stores, and
doesn't impose an ordering between cacheable and non-cacheable accesses (the
amusingly-named eieio instruction).  I am assuming here that smp_wmb is only
used for ordering stores to system memory so that another cpu will see them in
order.  It can't be used for enforcing any ordering that a device will see,
because it is just a gcc barrier on UP.

This also changes the spinlock/rwlock unlock code to use lwsync ("light-weight
sync") rather than eieio, since eieio doesn't order loads, and we need to
ensure that loads stay inside the spinlocked region.

When I sent the patch to uninline the spinlocks, I inadvertently left out
the change to arch/ppc64/Kconfig which defines the config symbol for
inlining the locks (CONFIG_SPINLINE now).  This patch adds it.  It also
adds a symbol CONFIG_PPC_SPLPAR which enables the code for calling the
hypervisor on shared-processor logically-partitioned system to yield the
physical processor to the lock holder when spinning.  (The code that
depends on this symbol is already present in arch/ppc64/lib/locks.c.)

We check nvram_fetch/nvram_store against -1, so better not make these

We update both regularly and there are other read only, heavily accessed

The patch below moves some declarations from C files into the appropriate
header file in include/asm-ppc (and removes an unused local variable in a

Matt Porter's recent changes broke the compile for non-4xx ppc32 systems,
unfortunately.  I get an error that mfdcr is not defined in
include/asm-ppc/ocp.h when compiling for powermac (reasonable, since the
mfdcr instruction only exists on 4xx processors).  The patch below fixes
it.

ext3 as module is not possible in 2.6.6, clear_pages, called from clear_page,
