x86_32 CONFIG_HIGHMEM64G with 5GB RAM hung when booting, after issuing
some "request_module: runaway loop modprobe binfmt-0000" messages in
trying to exec /sbin/init.
The binprm buf doesn't see the right ".ELF" header because sg_phys()
is providing the wrong physical addresses for high pages: a 32-bit
unsigned long is too small in this case, we need to use dma_addr_t.

the NULL dereference is here:
(gdb) list *0xffffffff804a9504
0xffffffff804a9504 is in natsemi_poll (drivers/net/natsemi.c:717).
712 return count;
713 }
714
715 static inline void __iomem *ns_ioaddr(struct net_device *dev)
716 {
717 return (void __iomem *) dev->base_addr;
718 }
719
which is this code from natsemi.c:
2227 struct net_device *dev = np->dev;
2228 void __iomem * ioaddr = ns_ioaddr(dev);
2229 int work_done = 0;
seems like the NAPI changes in -rc1 added an np->dev field but forgot to
initialize it ...
does the patch below fix the oops for you?

Subject: natsemi: fix oops, link back netdevice from private-struct

[NET]: Make NAPI polling independent of struct net_device objects.
added np->dev to drivers/net/natsemi.c's struct netdev_private, but
forgot to initialize that new field upon driver init. The result was
a predictable NULL dereference oops the first time the hardware
generated an interrupt.

P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.
When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears. Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.
This patch implements workaround for the board. If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.
This workaround fixes bugzilla #8923.

Local variable @action usage in ata_eh_reset() is a bit confusing.
It's used only to cache ehc->i.action to test reset masks after
clearing it; however, due to the generic name "action", it's easy to
misinterpret the local variable as containing the selected reset
method later. Also, the reason for caching the original value is easy
to miss.
This patch renames @action to @tmp_action and make it buffer newly
selected value instead to improve readability.

At the moment, balance_tasks() provides low level functionality for both
move_tasks() and move_one_task() (indirectly) via the load_balance()
function (in the sched_class interface) which also provides dual
functionality. This dual functionality complicates the interfaces and
internal mechanisms and makes the run time overhead of operations that
are called with two run queue locks held.
This patch addresses this issue and reduces the overhead of these
operations.

A full register dump along with stack backtrace would make the
"scheduling while atomic" message more helpful. Use show_regs() instead
of dump_stack() for this. We already know we're atomic in here (that is
why this function was called) so show_regs()'s atomicity expectations
are guaranteed.
Also, modify the output of the "BUG: scheduling while atomic:" header a
