With some small changes to kconfig makefile we can now
locate the defconfig files for i386 and x86_64 in
the configs/ subdirectory under x86.
make ARCH=i386 defconfig and make defconfig
works as expected also after this change.
But arch maintainers shall now update a defconfig file in

Moving the ARCH specific Makefiles for i386 and x86_64
required a litle bit tweaking in the top-lvel Makefile.
SRCARCH is now set in the top-level Makefile
because we need this info to include the correct

USB: usbserial - fix potential deadlock between write() and IRQ
usb_serial_generic_write() doesn't disable interrupts when taking port->lock,
and could therefore deadlock with usb_serial_generic_read_bulk_callback()

This patch (as1005) fixes a rather subtle problem. When
usb_set_configuration() registers the interfaces and their files in
sysfs, it doesn't expect those files to exist already. But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created. The result is an error
when usb_set_configuration() goes on to create those same files again.
The (not-so-great) solution is to have usb_set_configuration() remove
any existing files before creating them.

fix ssb_ohci_probe() build bug:

the reason was that this Kconfig combination was allowed:

CONFIG_USB_OHCI_HCD_SSB=y
the fix is to require a modular USB_OHCI_HCD build when SSB is modular.

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?

[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.
