[SCSI] megaraid: fix MMIO casts

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.

[PATCH] Centralise definitions of sector_t and blkcnt_t

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

Dominik Brodowski [Tue, 7 Nov 2006 02:52:16 +0000]
[PATCH] pcmcia: multifunction card handling fixes

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).

Many thanks to Fabrice Bellet for debugging and testing patches.

[PATCH] m68knommu: auto detect memory size on M5208EVB board

Here is a small patch to automatically detect the DRAM size on m520x.
It was generated against 2.6.17-uc0, and tested on an Intec 5208 dev board.

[S390] Reset infrastructure for re-IPL.

In case of re-IPL and diag308 doesn't work we have to reset all devices
manually and wait synchronously that each reset finished.
This patch adds the necessary infrastucture and the first exploiter of it.

Subsystems that need to add a function that needs to be called at re-IPL
may register/unregister this function via

struct reset_call {
struct reset_call *next;
void (*fn)(void);
};

void register_reset_call(struct reset_call *reset);
void unregister_reset_call(struct reset_call *reset);

When the registered function get called the context is:

- all cpus beside the current one are stopped
- all machine checks and interrupts are disabled
- prefixing is disabled
- a default machine check handler is available for use

The registered functions may not take any locks are sleep.

For the common I/O layer part of this patch:

Introduce a reset_call css_reset that does the following:
- clear all subchannels
- perform a rchp on all channel paths and wait for the resulting
  machine checks
This replaces the calls to clear_all_subchannels() and
cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
uses reipl_find_schid() to determine the subchannel id for a given
device id.
Also remove cio_reset_channel_paths() and friends since they are not
needed anymore.
