megaraid's MMIO RD*/WR* macros directly call readl() and writel() with
an 'unsigned long' argument. This throws a warning, but is otherwise OK
because the 'unsigned long' is really the result of ioremap(). This
setup is also OK because the variable can hold an ioremap cookie /or/ a
PCI I/O port (PIO).
However, to fix the warning thrown when readl() and writel() are passed
an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding
the same value as 'base'. This will silence the warnings, and also
cause an oops whenever these MMIO-only functions are ever accidentally
passed an I/O address.

CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
good reason.
Centralising the definition in linux/types.h means that arch maintainers
don't need to bother adding it, as well as fixing the problem with
x86-64 users being asked to make a decision that has absolutely no
effect.
The H8/300 porters seem particularly confused since I'm not aware of any

ip_summed changes last summer had missed that one. As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now. IOW,
->csum is interpreted as offset of checksum in the packet. net/core/*
will both read and modify the value as that offset, with obvious
reasons. At the very least it's a remote memory corruptor.

This is an update to the AT91 CompactFlash driver.
We replace the hard-coded "chip select 4" with the chip-select value
passed via platform_data. The configuration of the EBI memory
controller to enable Compact Flash access is now also handled in the
platform setup code and not in the driver.

s->functions needs to be initialized earlier, for the "let's see
how high it increases" approach means that pcmcia_request_irq()
(which makes use of this value) is confused, and might request
an exclusive IRQ first even though it is not supposed to.
Also, a CIS override autoloaded using the firmware loader may
allow for the use of more or less functions in a multifunction
card. Therefore, we may need to schedule a call to add this
second function later on, or simply remove the other function
(it's always the first -valid- function which reaches this
codepath).
