Grant Likely 9b9129e739 [POWERPC] typo fix and whitespace cleanup on mpc52xx-uart driver
Single typo fix and whitespace changes.  In preparation for heavy
changes to this driver when support for arch/powerpc is added.
Since the driver will be changing significantly anyway, then may
as well take the opportunity to clean it up first.

Ralf Baechle 4f8b5c7096 [MIPS] Fix atomic.h build errors.
For the definition of atomic64_t atomic.h was relying on <asm/types.h>

d89d8e0637a5e4e0a12e90c4bc934d0d4c335239 this was happening as a

ipc/compat.c seems more complete.  We can use it for both N32 and O32.

Alan 8e42a5a220 [PATCH] pata_ali: small fixes
Switch to pci_get_bus_and_slot because some x86 systems seem to be
handing us a device with dev->bus = NULL. Also don't apply the isa fixup
to revision C6 and later of the chip.

Really we need to work out wtf is handing us pdev->bus = NULL, but firstly
and more importantly we need the drivers working.

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.

Heiko Carstens 6b4044bdd1 [S390] extmem unbalanced spin_lock.
segment save will exit with a lock held if the passed segment doesn't
exist. Any subsequent call to segment_save will lead to a deadlock.
Fix this and give up the lock before returning.

Horst Hummel 645c98c8b6 [S390] return 'count' for successful execution of dasd_eer_enable.
Currently the return value of 'dasd_eer_enable' is returned - even if the
function returned '0'. Now return 'count' for successful execution.
