scan_lru_pages returns pfn. So, it's type should be "unsigned long"
not "int".Note: I guess this has been work until now because memory hotplug tester's
machine has not very big memory....

For power management at91_pm_enter() routine, use the cpu_do_idle() for a
rock solid "wait for interrupt" implementation.
For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as
we can access RAM even while in self-refresh mode.
We keep plain access to CP15 for at91rm9200 as this feature is not
available: instructions have to be in a single cache line.Signed-off-by: Nicolas Ferre

Several at91sam9 chips need the alternate reset procedure to be sure to halt
SDRAM smoothly before resetting the chip.
This is an extension of previous patch "Fix AT91SAM9G20 reset" to all chips
affected.Signed-off-by: Nicolas Ferre
-
Generalize assembler reset routine to allow use on several at91sam9 chips.
This patch replace double definitions of SDRAM controller registers and RSTC
registers with use of classical header files.For this rework, we remove the not needed icache flush as it is already
done in the calling function: arm_machine_restart().Rename at91sam9g20_reset.S to generalize to several chips.

In the MN10300 arch, we occasionally see an assertion being tripped in
alloc_cwqs() at the following line:/* just in case, make sure it's actually aligned */
---> BUG_ON(!IS_ALIGNED(wq->cpu_wq.v, align));
return wq->cpu_wq.v ? 0 : -ENOMEM;The values are:
wa->cpu_wq.v => 0x902776e0
align => 0x100and align is calculated by the following:
const size_t align = max_t(size_t, 1 << WORK_STRUCT_FLAG_BITS,
__alignof__(unsigned long long));This is because the pointer in question (wq->cpu_wq.v) loses some of its
lower bits to control flags, and so the object it points to must be
sufficiently aligned to avoid the need to use those bits for pointing to
things.Currently, 4 control bits and 4 colour bits are used in normal
circumstances, plus a debugging bit if debugging is set. This requires
the cpu_workqueue_struct struct to be at least 256 bytes aligned (or 512
bytes aligned with debugging).PERCPU() alignment on MN13000, however, is only 32 bytes as set in
vmlinux.lds.S. So we set this to PAGE_SIZE (4096) to match most other
arches and stick a comment in alloc_cwqs() for anyone else who triggers
the assertion.Reported-by: Akira Takeuchi

The only caller (svc_send) has already checked XPT_DEAD.
Signed-off-by: J. Bruce Fields
-
If any xprt marked DEAD is also left BUSY for the rest of its life, then
the XPT_DEAD check here is superfluous--we'll get the same result from
the XPT_BUSY check just after.Signed-off-by: J. Bruce Fields
-
As long as DEAD exports are left BUSY, and svc_delete_xprt is called
only with BUSY held, then svc_delete_xprt() will never be called on an
xprt that is already DEAD.Signed-off-by: J. Bruce Fields
-
Once an xprt has been deleted, there's no reason to allow it to be
enqueued--at worst, that might cause the xprt to be re-added to some
global list, resulting in later corruption.Also, note this leaves us with no need for the reference-count
manipulation here.Reviewed-by: NeilBrown

Add optional blockread function to interface driver. If available
the chip driver uses it for data register access. For 12 bit device
it reads 6 bytes to get 3*16bit data. For 8 bit device it reads out
