The 32-bit version and 64-bit version are almost equal. Unify them. This

For the definition of atomic64_t atomic.h was relying on
having been included previously. Before changeset
d89d8e0637a5e4e0a12e90c4bc934d0d4c335239 this was happening as a

N32 SysV IPC system calls should use 32-bit compatible code.
arch/mips/kernel/linux32.c have similar compatible code for O32, but
ipc/compat.c seems more complete. We can use it for both N32 and O32.This patch should fix these problems (and other possible problems):

Switch to pci_get_bus_and_slot because some x86 systems seem to be
handing us a device with dev->bus = NULL. Also don't apply the isa fixup
to revision C6 and later of the chip.Really we need to work out wtf is handing us pdev->bus = NULL, but firstly
and more importantly we need the drivers working.Signed-off-by: Alan Cox

The lock dependency validator adds a bunch of extra stack frames to
the stack, which can cause stack overflows. Especially seen on 31 bit
where the small stack is only 4k.Signed-off-by: Heiko Carstens

In io_subchannel_register(), it is better to just reprobe the current

If I/O was running on a just varied off chpid, it will be terminated.
If this was a common I/O layer internal I/O, it needs to be retried.Signed-off-by: Cornelia Huck
Signed-off-by: Martin Schwidefsky -
If the last path to a device is gone after a chpid has been varied
off, putting it on the slow queue doesn't prevent a device driver
from still attempting to use it (it may stay on the slow queue for a
long time). Instead, trigger a verify event which will prevent I/O
attempts from the device driver immediately.Signed-off-by: Cornelia Huck

VMALLOC_END on 31bit should be 0x8000000UL instead of 0x7fffffffL.
The page mask which is used to make sure memory_end is on 4MB/2MB
boundary is wrong and not needed. Therefore remove it.

machines with 4TB and more memory.Signed-off-by: Heiko Carstens

Use a wrapper for copy_to/from_user to chose the best usercopy method.

Avoid the tprot loop if diag260 works and reports that there are no
