Konstantin Khlebnikov 314e51b985 mm: kill vma flag VM_RESERVED and mm->reserved_vm counter
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.

Linus Torvalds 61464c8357 ARM: soc: general cleanups
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.

Omar Ramirez Luna 424d56ec3c staging: tidspbridge: fix uuid strings
Commit 8cb05f4b54 (staging:
tidspbridge: eliminate uuid_uuid_to_string), not only broke
compilation but also functionality for tidspbridge driver.

So:
- Replace remaining instances of uuid_uuid_to_string with snprintf
  to fix compilation.
- Fix the format from %pU to %pUL.
- Since these UUIDs are used in the firmware to reference section
  names, the firmware doesn't follow the standard uuid delimiter '-'
  it uses '_' instead. The driver can follow the standard convention
  however for dsp sections we must transform the uuid to what is
  expected by the firmware. E.g.:

  tidspbridge sees: 24BC8D90-BB45-11D4-B756-006008BDB66F
  firmware expects: .24BC8D90_BB45_11D4_B756_006008BDB66F

Instead now use ioremap. This is needed for 3.4 since this change

These solves the following compilation breaks:

drivers/staging/tidspbridge/core/tiomap3430.c:
    In function ‘bridge_brd_start’:
drivers/staging/tidspbridge/core/tiomap3430.c:425:4:

drivers/staging/tidspbridge/core/wdt.c:56:2:
    error: implicit declaration of function ‘OMAP2_L4_IO_ADDRESS’

For control registers a new function needs to be defined so we
can get rid of a layer violation, but that approach must be queued
for the next merge window.

Víctor Manuel Jáquez Leal 18ff159260 staging: tidspbridge: remove node_init() and node_exit()
The node module has a node_init() and a node_exit() whose only purpose
is to keep a reference counting which is not used at all.

This patch removes these functions and the reference count variable.

There is no functional changes.

Omar Ramirez Luna 08cd9ef4ec staging: tidspbridge: detect wdt3 feature at runtime
In order to detect WDT feature on the dsp code, we need to
find the symbol used to enable it inside the baseimage.

This should fix the warning comming from L3 driver:

    WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq...
    In-band Error seen by IVA_SS  at address 0
    ...

That occurs because the dsp tries to access wdt3 registers when the clock
for those registers is not enabled.

Omar Ramirez Luna 18db4fe098 staging: tidspbridge: always compile dsp wdt code
In order to detect it at runtime, we need the code handling wdt
clock available at runtime to decide whether to enable or disable
based on the baseimage symbols. Default timeout has been set to 5
seconds.

Downside is that we will lose the option to set a custom timeout
for overflow, but than can be added (if needed) as part of debugfs.

Omar Ramirez Luna 2573897816 staging: tidspbridge: fix bridge_open memory leaks
There are two members of pr_ctxt allocated during bridge_open that
are never freed resulting in memory leaks, these are stream_id and
node_id, they are now freed on release of the handle (bridge_release)
right before freeing pr_ctxt.

Error path for bridge_open was also fixed since the same variables
could result in memory leaking due to missing handling of failure
scenarios. While at it, the indentation changes were introduced to
avoid interleaved goto statements inside big if blocks.

Víctor Manuel Jáquez Leal 451196a338 staging: tidspbridge: remove CONFIG_TIDSPBRIDGE_DEBUG
Since all the asserts and DBC macros are gone, the kconfig macro
CONFIG_TIDSPBRIDGE_DEBUG is not almost used, but for printing trace messages.

Since it is almost not used, I don't see any case for keep it churning the
configuration menu.

This patch removes completely the kconfig macro CONFIG_TIDSPBRIDGE_DEBUG,
using only TIDSPBRIDGE_BACKTRACE for enabling the debug trace messages.

This macro is only valid when CONFIG_TIDSPBRDIGE_DEBUG is enabled and it only
prints a log message, it is not a real assertion mechanism like BUG_ON() or
WARN_ON().

It is better to remove them: less code to maintain.

The kernel does not use a "Design by Contract" approach, and it is only
activated in the module if CONFIG_TIDSPBRDIGE_DEBUG is enabled, so they are
executed rarely. It is better to remove them: less code to maintain.

Joe Perches 8900f00b15 staging: tidspbridge: Rename module from bridgedriver to tidspbridge
tidspbridge when built as a module is named bridgedriver.

bridgedriver is not a particularly good module name.

tidspbridge is what the source is named.  That seems
a more appropriate module name too as it describes
the hardware function better.
