There is little rationale for marking bus_for_each_drv() __must_check.
It is more of an iteration helper than a real function. You don't know
in advance which callback it will be used on, so you have no clue how
important it can be to check the returned value. In practice, this
helper function can be used for best-effort tasks.
As a matter of fact, bus_for_each_dev() is not marked __must_check.
So remove it from bus_for_each_drv() as well. This is the same that
was done back in October 2006 by Russell King for
device_for_each_child(), for exactly the same reasons.

The kernel/hotplug sysctl variable (/proc/sys/kernel/hotplug file) was
made conditional on CONFIG_NET by commit
f743ca5e10 (applied in 2.6.18) to fix
problems with undefined references in 2.6.16 when CONFIG_HOTPLUG=y &&
!CONFIG_NET, but this restriction is no longer needed.
This patch makes the kernel/hotplug sysctl variable depend only on
CONFIG_HOTPLUG.

We reserve the 3.75GB - 4GB region of PCIe address space for device to
device transfers, making the corresponding physical memory under
direct mapping unavailable for DMA.
To allow for PCIe DMA to all physical memory we map this chunk of
physical memory with BAR1. Because of the resulting discontinuity in
the mapping function, we remove a page of memory at each end of the
range so multi-page DMA buffers can never be allocated that span the
range.

The sixth argument of notify_die() is a signal number, the fifth is a
trap number.
Instead of passing a signal number in a randomly selected argument,
pass it in the sixth. Extract the exception code from regs and pass
that as the trap number.
Get rid of redundant cast, and remove some gratuitous spaces.
Nobody actually does anything with the signal number or trap number,
but we might as well populate them with sensible values.

A 'select EXPORT_UASM' in Kconfig will cause the uasm to be exported
for use in modules. When it is exported, all the uasm data and code
cease to be __init and __initdata.
Also daddiu_bug cannot be __cpuinitdata if uasm is exported. The
