MIPS: SNI: Correct NULL test

2010-02-10T21:15:45+00:00

Test the value that was just allocated rather than the previously tested one.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@r@
expression *x;
expression e;
identifier l;
@@

if (x == NULL || ...) {
    ... when forall
    return ...; }
... when != goto l;
    when != x = e
    when != &x
*x == NULL
//

MIPS: Move several variables from .bss to .init.data

2009-12-17T01:57:27+00:00

Several static uninitialized variables are used in the scope of __init
functions but are themselves not marked as __initdata.  This patch is to put
those variables to where they belong and to reduce the memory footprint a
little bit.

Also, a couple of lines with spaces instead of tabs were fixed.

MIPS: Fixup last users of irq_chip->typename

2009-12-17T01:57:21+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

MIPS: Add IRQF_TIMER flag for timer interrupts

2009-11-02T11:00:02+00:00

Along the lines of d6c585a4342a2ff627a29f9aea77c5ed4cd76023, add IRQF_TIMER
flag for all timer interrupts  This ensures that timer interrupts won't be
disabled on suspend and not threaded for PREEMPT_RT.

timekeeping: Increase granularity of read_persistent_clock()

2009-08-15T08:55:46+00:00

The persistent clock of some architectures (e.g. s390) have a
better granularity than seconds. To reduce the delta between the
host clock and the guest clock in a virtualized system change the 
read_persistent_clock function to return a struct timespec.

MIPS: Build fix - include into all smp_processor_id() users.

2009-06-24T17:34:39+00:00

Some of the were relying into smp.h being dragged in by another header
which of course is fragile.   uses smp_processor_id()
only in macros and including smp.h there leads to an include loop, so
don't change cpu-info.h.

mips: remove driver_data direct access of struct device

2009-06-16T04:30:27+00:00

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.
