staging: tidspbridge: delete unused mmu functions

2012-10-24T23:31:32+00:00

This should get rid of warnings of the type:

warning: passing argument 1 of '' discards qualifiers from pointer target type
 note: expected 'void *' but argument is of type 'const void *'

staging: tidspbridge: ioremap physical address of the stack segment in shm

2012-10-24T23:31:31+00:00

Due to data type change, readl can no longer receive a u32.

staging: tidspbridge: ioremap dsp sync addr

2012-10-24T23:31:31+00:00

Change the type of sync_addr to 'void __iomem *' and ioremap the
physical address in the shared memory so we can access it using
_raw_*. While at it, drop 'dw_' prefix.

Fix the warning associated with dsp's sync_addr:

warning: passing argument 2 of '__raw_writel' makes pointer from integer without a cast
../io.h:88: note: expected 'volatile void *' but argument is of type 'u32'

staging: tidspbridge: change type to __iomem for per and core addresses

2012-10-24T23:31:31+00:00

Currently per_pm_base and core_pm_base are declared as u32, however
_raw_* changed the data type, since:

195bbca ARM: 7500/1: io: avoid writeback addressing modes for __raw_ accessors

This should fix warnings for per and core accesses:

staging: tidspbridge: drop const from custom mmu implementation

2012-10-24T23:31:31+00:00

Custom mmu functions receive a 'const void __iomem *', all the
callers pass a 'void __iomem *', so drop the const to fix the
warnings like:

warning: passing argument 2 of '__raw_writel' discards qualifiers from pointer target type
../io.h:88: note: expected 'volatile void *' but argument is of type 'const void *'

staging: tidspbridge: request the right irq for mmu

2012-10-24T23:31:30+00:00

Requested irq for mmu is currently conflicting with a DMA irq
due to recent changes to irq header files, now the offset for the
start of the interrupt controller numbering has changed.

This should be removed during a future migration to omap-iommu,
for now it is hardcoded.

mm: kill vma flag VM_RESERVED and mm->reserved_vm counter

2012-10-09T07:22:19+00:00

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:

 | effect                 | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump      | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock           | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

This patch removes reserved_vm counter from mm_struct.  Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.

Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-10-02T01:19:05+00:00

Pull ARM soc general cleanups from Olof Johansson:
 "This is a large branch that contains a handful of different cleanups:

   - Fixing up the I/O space remapping on PCI on ARM.  This is a series
     from Rob Herring that restructures how all pci devices allocate I/O
     space, and it's part of the work to allow multiplatform kernels.
   - A number of cleanup series for OMAP, moving and removing some
     headers, sparse irq rework and in general preparation for
     multiplatform.
   - Final removal of all non-DT boards for Tegra, it is now
     device-tree-only!
   - Removal of a stale platform, nxp4008.  It's an old mobile chipset
     that is no longer in use, and was very likely never really used
     with a mainline kernel.  We have not been able to find anyone
     interested in keeping it around in the kernel.
   - Removal of the legacy dmaengine driver on tegra

  + A handful of other things that I haven't described above."

Fix up some conflicts with the staging tree (and because nxp4008 was
removed)

staging: tidspbridge: fix return value check in dsp_wdt_init()

2012-09-21T16:02:23+00:00

In case of error, the function clk_get() returns ERR_PTR()
and never returns NULL pointer. The NULL test in the error
handling should be replaced with IS_ERR().

ARM: omap: move platform_data definitions

2012-09-19T15:39:52+00:00

Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.

This moves such data out of the omap include directories
