For all the Samsung SoC based boards which have the platform data for s3c-fb driver, the 'default_win' element in the platform data is removed and the lcd panel video timing values are moved out of individual window configuration data.

The display controller window data should contain window configuration data for only one type of lcd panel. So, for real6410 and mini6410 boards, split the existing display controller window data, which contains window configuration data for two different types of lcd panels, into two seperate instances and register one of them depending on the type of the lcd panel detected at runtime. This is a prerequisite change for a subsequent commit that reorders the platform data of display controller by moving video interface timing out of window setup data.

The decision to enable or disable the data output to the lcd panel from the controller need not be based on the value of 'default_win' element in the platform data. Instead, the data output to the panel is enabled if any of the windows are active, else data output is disabled.

The video interface timing is independent of the window setup data. The resolution of the window can be smaller than that of the lcd panel to which the video data is output. So move the video timing data from the per-window setup data to the platform specific section in the platform data. This also removes the restriction that atleast one window should have the same resolution as that of the panel attached.

I have a new optimized x86 "strncpy_from_user()" that will use these same helper functions for all the same reasons the name lookup code uses them. This is preparation for that. This moves them into an architecture-specific header file. It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this. (and if it turns out that non-x86 architectures don't start using this, then having it in an architecture-specific header is still the right thing to do, of course) Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

That function calls mp_find_ioapics to get the 'struct ioapic' structure - which along with the mp_irq[x] is used to figure out the default values and the polarity/trigger overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt. The proper fix for this is going in v3.5 and adds an x86_io_apic_ops struct so that platforms can override it. But for v3.4 lets carry this work-around. This patch does that by providing a slightly different variant of the fake IOAPIC entries. Signed-off-by: NKonrad Rzeszutek Wilk <konrad.wilk@oracle.com>

As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0 ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree.

With commit c334bc15 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y. Since clk_disable_unused is called as lateinitcall, there can be more than a few workqueues executing off secondary CPU(s). The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused. We ensure instead that the entire list traversal is protected by the lock allowing for parent child clock traversal which could be potentially be done by runtime operations to be safe as well.

The commit 996bc8ae (mmc: sh_mobile_sdhi: do not manage PM clocks manually) modified the sh_mobile_sdhi driver to remove the clk_enable/clk_disable. So, we need to change the "CLKDEV_CON_ID" to "CLKDEV_DEV_ID". If we don't change this, we will see the following error from the driver: sh_mobile_sdhi sh_mobile_sdhi.0: timeout waiting for hardware interrupt (CMD52) Signed-off-by: NYoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
