ext4 does not work on s390 because ext2_find_next_bit is broken. Fortunately
this function is only used by ext4. The function uses ffs which does not work
analog to ffz. The result of ffs has an offset of 1 which is not taken into
account. To fix this use the low level __ffs_word function directly instead
of the ill defined ffs.
In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit
by passing the bit offset into __ffz_word instead of adding it after the
function call returned.

The usual problem: the suspend function when interrupts are
already disabled calls smp_call_function which is not allowed with
interrupt off. But at this point all the other CPUs should be already
down anyways, so it should be enough to just drop that.
This patch should fix that problem at least by fixing cpu hotplug&

this commit activated a macro which was dormant before due to (buggy)
macro side-effects.
I've looked through various datasheets and found that the GXm and GXLV
Geode processors don't have an incrementor.
Remove the incrementor setup entirely. As the incrementor value
differs according to clock speed and we would hope that the BIOS
configures it correctly, it is probably the right solution.

Recent of_platform changes made of_bus_type_init() overwrite the bus
type's .dev_attrs list, meaning that the "name" attribute that ibmebus
devices previously had is no longer present. This is a user-visible
regression which breaks the userspace eHCA support, since the eHCA
userspace driver relies on the name attribute to check for valid
adapters.
This fixes it by providing the "name" attribute in the generic OF
device code instead. Tested on POWER.

So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.
