      remove inode_setattr · 1025774c
      由 Christoph Hellwig 提交于 
      Replace inode_setattr with opencoded variants of it in all callers.  This
moves the remaining call to vmtruncate into the filesystem methods where it
can be replaced with the proper truncate sequence.

In a few cases it was obvious that we would never end up calling vmtruncate
so it was left out in the opencoded variant:

 spufs: explicitly checks for ATTR_SIZE earlier
 btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier
 ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above

In addition to that ncpfs called inode_setattr with handcrafted iattrs,
which allowed to trim down the opencoded variant.

      powerpc/5200: add mpc5200_psc_ac97_gpio_reset · cfa6a88c
      由 Eric Millbrandt 提交于 
      Work around a silicon bug in the ac97 reset functionality of the
mpc5200(b).  The implementation of the ac97 "cold" reset is flawed.
If the sync and output lines are high when reset is asserted the
attached ac97 device may go into test mode.  Avoid this by
reconfiguring the psc to gpio mode and generating the reset manually.

From MPC5200B User's Manual:
"Some AC97 devices goes to a test mode, if the Sync line is high
during the Res line is low (reset phase). To avoid this behavior the
Sync line must be also forced to zero during the reset phase. To do
that, the pin muxing should switch to GPIO mode and the GPIO control
register should be used to control the output lines."

      of/address: Clean up function declarations · 22ae782f
      由 Grant Likely 提交于 
      This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.

This patch also fixes some of the asm/prom.h ordering issues.  It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

      powerpc: Use IRQF_NO_SUSPEND not IRQF_TIMER for non-timer interrupts · ba461f09
      由 Ian Campbell 提交于 
      kw_i2c_irq and via_pmu_interrupt are not timer interrupts and
therefore should not use IRQF_TIMER. Use the recently introduced
IRQF_NO_SUSPEND instead since that is the actual desired behaviour.

      powerpc: Clean up obsolete code relating to decrementer and timebase · d75d68cf
      由 Paul Mackerras 提交于 
      Since the decrementer and timekeeping code was moved over to using
the generic clockevents and timekeeping infrastructure, several
variables and functions have been obsolete and effectively unused.
This deletes them.

In particular, wakeup_decrementer() is no longer needed since the
generic code reprograms the decrementer as part of the process of
resuming the timekeeping code, which happens during sysdev resume.
Thus the wakeup_decrementer calls in the suspend_enter methods for
52xx platforms have been removed.  The call in the powermac cpu
frequency change code has been replaced by set_dec(1), which will
cause a timer interrupt as soon as interrupts are enabled, and the
generic code will then reprogram the decrementer with the correct
value.

This also simplifies the generic_suspend_en/disable_irqs functions
and makes them static since they are not referenced outside time.c.
The preempt_enable/disable calls are removed because the generic
code has disabled all but the boot cpu at the point where these
functions are called, so we can't be moved to another cpu.

      of: remove of_default_bus_ids · c0dd394c
      由 Jonas Bonn 提交于 
      This list used was by only two platforms with all other platforms defining an
own list of valid bus id's to pass to of_platform_bus_probe.  This patch:

i)   copies the default list to the two platforms that depended on it (powerpc)
ii)  remove the usage of of_default_bus_ids in of_platform_bus_probe
iii) removes the definition of the list from all architectures that defined it

Passing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the
function returns no error in that case as the NULL value is equivalent to an
empty list.

      of: Merge of_platform_bus_type with platform_bus_type · eca39301
      由 Grant Likely 提交于 
      of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code.  Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.

This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead.  A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.

After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.
