I was gently reminded that there are per-cpu forms of the EXPORT_SYMBOL macros.

Only the address needs alignment of mask bits, length should work with
a relaxed alignment check.
Signed-off-by: Jens Axboe <axboe@suse.de>
[ This is take 2: make the length check be for 16-byte alignment, not
just word alignment. That should hopefully keep everybody happy,
while still allowing CD writing with DMA ]

When I sent in the patch adding the code for the kernel to tell the
firmware about its capabilities on pSeries machines, I included the
function to give the capabilities to firmware but somehow forgot the
hunk that adds the call to the new function. This patch adds the
call.

It cannot work properly, so just ignore it in drr

This patch adds is_multicast_ether_addr() to go along with
is_valid_ether_addr() and friends. It then changes
is_valid_ether_addr() to use the new macro, and fixes up the comment
on that function to move implementation details out of the API doco.

Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu().
It is possible that the bootcode may be loading code from nvram during
this call and stopping the cpu without getting the lock may cause
uncompleted nvram data to be left in the nvram data register. Subsequent
calls to read/write nvram data will fail.

This improves the bridge local receive path by avoiding going
through another softirq. The bridge receive path is already being called
from a netif_receive_skb() there is no point in going through another
receiveq round trip.
Recursion is limited because bridge can never be a port of a bridge
so handle_bridge() always returns.

The call to io_block_mapping was creating an invalid BAT entry because the
value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min). This
change removes the io_block_mapping call since these registers can easily
be mapped using ioremap at the point of use.

The error checking for emulation of load string instructions was overly
generous and would cause certain valid forms of the instructions to be
treated as illegal. We drop the range checking since the architecture
allows this to be boundedly undefined. Tests on CPUs that support these
instructions appear not do cause illegal instruction traps on range errors
and just allow the execution to occur.
Thanks to Kim Phillips for debugging this and figuring out what real HW was
doing.

This patch adds on-chip PCI bridge support for the PQ2 family. The
incomplete existent code is updated with interrupt handling stuff and
board-specific bits for 8272ADS and PQ2FADS; the related files were renamed
(from m8260_pci to m82xx_pci) to be of more generic fashion. This is
tested with 8266ADS and 8272ADS, should work on PQ2FADS as well.

This var is currently useless, as it's apparent from reading the code. Until
2.6.11 it was used in some code related to jail mode, in the same proc.:
if(jail){
while(!reading) sched_yield();
}
jail mode has been dropped, together with that use, so let's finish dropping
this.
Also, remove some other useless definitions I met.

Fix it a bit (after some cross checking with "man arch_prctl"). There were:
*) typos FS/GS and back
*) FS in place of FS_BASE (and the same for GS)
*) the procedure used put_user on &addr, where addr was the parameter (i.e.
changed its param with put_user, completely useless) rather than interpreting
addr as a pointer, as requested in this case (see the man page).

After porting this fixlet to UML:
http://linux.bkbits.net:8080/linux-2.5/cset@41791ab52lfMuF2i3V-eTIGRBbDYKQ
, I've also added a warning which should refuse compilation with insane values
for PREEMPT_ACTIVE... maybe we should simply move PREEMPT_ACTIVE out of
architectures using GENERIC_IRQS.

Port Paulus's ppc64 fix to sh:
When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped
from 9 (for ppc64) up to 12. Consequently, the PREEMPT_ACTIVE bit is now
within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when
PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.

Until now, FRAME_POINTER was set = DEBUG_INFO for UML. Change it to be the
default way, so that it can be enabled alone (for instance to get better
backtraces on crashes). The call-trace dumper which uses the frame pointer is
not yet in, I'm going to introduce it in a separate patch.
