When there is a PCI-X mode 2 capable device behind the HT<->PCI-X
bridge, the pci core decides that the device has the extended 4K
config space, even though the bus is not operating in mode 2. This is
because the u3_ht pci ops silently accept offsets greater than 255 but
use only the 8 least significant bits, which means reading at offset
0x100 gets the data at offset 0x0, and causes confusion for lspci.
Reject accesses to configuration space offsets greater than 255.

This reverts commits 11012d419c and
40dd2d20f2, which allowed us to use the
MMIO accesses for PCI config cycles even without the area being marked

Those changes were needed for EFI-environment Intel macs, but broke some
newer Intel 965 boards, so for now it's better to revert to our old
2.6.17 behaviour and at least avoid introducing any new breakage.

This changes the writeX family of functions to have a sync instruction
before the MMIO store rather than after, because the generally expected
behaviour is that the device receiving the MMIO store can be guaranteed
to see the effects of any preceding writes to normal memory.
To preserve ordering between writeX and readX, and to preserve ordering
between preceding stores and the readX, the readX family of functions
have had an sync added before the load.
Although writeX followed by spin_unlock is not officially guaranteed
to keep the writeX inside the spin-locked region unless an mmiowb()
is used, there are currently drivers that depend on the previous
behaviour on powerpc, which was that the mmiowb wasn't actually required.
Therefore we have a per-cpu flag that is set by writeX, cleared by
__raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is
set, __raw_spin_unlock does a sync and clears it.
This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a
sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus
doesn't need the per-cpu flag.

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
The original sh64 toolchains required that we tune the ISA
level accordingly to not have head.S/entry.S blow up. With
current toolchains, this is no longer the case, and the
syntax magically changed as well, causing all current
toolchains to die a horrible death.
Incidentally, code generation in other parts of the kernel
is now significantly complex enough that none of the older
toolchains make it very far these days, so there's not
even any point in preserving legacy compatability via
as-option.
This fixes a long-standing issue, as noted here:

Patch from Ben Dooks
The IRQ_EINT0 through IRQ_EINT3 handling has changed
on the S3C2412 from the previous SoCs in the range,
and thus we need to add code to handle this.
The changes come about due to these IRQs being
displayed in two different registers, and needing to
be acked and masked in both.

Patch from Ben Dooks
The s3c244x-irq.c code makes the mistake of adding
the same drive to two different sys-classes. This
causes the class lists to become corrupted and the
suspend code to OOPS.

The sn_cpu_init() is required for cpu initialization on SN platforms.
Change __init to __cpuinit so that the function is not freed with init code/data.

The SN PROM uses the register stack in the slave loop. The contents
must be preserved for the OS to return to the slave loop via offlining
a cpu or for kexec. A 'flushrs" is needed to force the stack to be written
to memory prior to changing bspstore.

The syscalls set/get_robust_list must not be wired up until
futex_atomic_cmpxchg_inatomic is implemented. Otherwise the kernel will
hang in handle_futex_death.
