329456d1ff ssb: fix init regression with SoCs
This fixes a Data bus error on some SoCs. The first fix for this
problem did not solve it on all devices.
    commit 6ae8ec2786
    Author: Rafał Miłecki <zajec5@gmail.com>
    Date:   Tue Jul 5 17:25:32 2011 +0200
        ssb: fix init regression of hostmode PCI core

In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is
accessed, but the sprom only exists when the ssb bus is connected over
a PCI bus to the rest of the system and not when the SSB Bus is the
main system bus. SoCs sometimes have a PCI host controller and there
this code will not be executed, but there are some old SoCs with an PCI
controller in client mode around and ssb_pcicore_fix_sprom_core_index()
should not be called on these devices too. The PCI controller on these
devices are unused, but without this fix it results in an Data bus
error when it gets initialized.

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_register_driver() so
we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:

 struct spi_driver _driver = {

0ee332c145 memblock: Kill early_node_map[]
Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP -
there's no user of early_node_map[] left.  Kill early_node_map[] and
replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP.  Also,
relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h
as page_alloc.c would no longer host an alternative implementation.

This change is ultimately one to one mapping and shouldn't cause any
observable difference; however, after the recent changes, there are
some functions which now would fit memblock.c better than page_alloc.c
and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK
doesn't make much sense on some of them.  Further cleanups for
functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice.

-v2: Fix compile bug introduced by mis-spelling
 CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in
 mmzone.h.  Reported by Stephen Rothwell.

df7c1ca229 usb: Fix PS3 EHCI suspend
The EHCI USB controller of the Cell Super Companion Chip used in the PS3
will stop the root hub after all root hub ports are suspended.  When in
this condition the ehci-hcd handshake routine will return -ETIMEDOUT and
the USB runtime suspend sequence will fail.  The STS_HLT bit will not be
set, so inspection of the frame index is used to test for the condition.

Add a new routine handshake_for_broken_root_hub() that is called after
an unsuccessful -ETIMEDOUT handshake.  On PS3 handshake_for_broken_root_hub()
will test for the condition, and if found will return success to allow the
USB suspend to complete.  For all other platforms
handshake_for_broken_root_hub() will return -ETIMEDOUT

3506c0d507 DMA: PL330: Remove pm_runtime_xxx calls from pl330 probe/remove
amba_probe() now calls pm_runtime_get_noresume() and pm_runtime_enable()
for the devices before the device probe is called. Hence we don't need
to call pm_runtime_get_xxx and pm_runtime_enable() in device probe again.
In the same way, since amba_remove() calls the respective pm_runtime
functions, those functions need not be called from device remove.

This patch fixes following run time error with pl330 driver.

dma-pl330 dma-pl330.0: Unbalanced pm_runtime_enable!
dma-pl330 dma-pl330.0: failed to get runtime pm
