Add a PageSlab() check before adding the _mapcount value to /kpagecount. page->_mapcount is in a union with the SLAB structure so for pages controlled by SLAB, page_mapcount() returns nonsense. Signed-off-by:

- ->low_ino is write-once field -- reading it under locks is unnecessary. - /proc/$PID stuff never reaches pde_put()/free_proc_entry() -- PROC_DYNAMIC_FIRST check never triggers. - in proc_get_inode(), inode number always matches proc dir entry, so save one parameter. Signed-off-by:

A call to va_start() must always be followed by a call to va_end() in the same function. In fs/reiserfs/prints.c::print_block() this is not always the case. If 'bh' is NULL we'll return without calling va_end(). One could add a call to va_end() before the 'return' statement, but it's nicer to just move the call to va_start() after the test for 'bh' being NULL. Signed-off-by:

Because GPIOs can have crucial functions especially in embedded systems, we are better safe than sorry regarding their configuration. For gpio_request, the documentation is simply enforced: <quote>"The return value of gpio_request() must be checked."</quote> For gpio_direction_* and gpio_request_*, we now act accordingly.

The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c. The new driver has been in the tree for a little while, and has received some testing; it's time to mark the old one as deprecated. I'm thinking removal around 2.6.40 would be good, provided we're not missing critical functionality in the newer driver. Signed-off-by:

Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver. Signed-off-by:

This adds (well, re-adds actually) handling for events/IRQs through cs5535 GPIOs. In the wild and wooly world of CS5535, setup_event() is for assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the pair to trigger IRQs. These should really only be used in highly platform-specific drivers (such as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes the driver to become X86-specific. Signed-off-by:

rtc-cmos was setting suspend/resume hooks at the device_driver level. However, the platform bus code (drivers/base/platform.c) only looks for resume hooks at the dev_pm_ops level, or within the platform_driver. Switch rtc_cmos to use dev_pm_ops so that suspend/resume code is executed again. Paul said: : The user visible symptom in our (XO laptop) case was that rtcwake would : fail to wake the laptop. The RTC alarm would expire, but the wakeup : wasn't unmasked. : : As for severity, the impact may have been reduced because if I recall : correctly, the bug only affected platforms with CONFIG_PNP disabled.

request_mem_region() will call kzalloc to allocate memory for struct resource. release_resource() unregisters the resource but does not free the allocated memory, thus use release_mem_region() instead to fix the memory leak. Also add a missing iounmap() in omap_rtc_remove(). Signed-off-by:

It seems there is a small problem of VGA palette corruption on EFI machine. When the kernel initializes the architecture, it checks if the machine is a EFI machine and assumes that a VGA console can exist. When it initializes the console in vgacon_startup it checks if it can really use the VGA console. I think this is where a check is missing. Currently, the function can fail if a VESA boot mode is detected but not if a EFI boot mode was used. Thus vgacon_startup() doesn't fail and initialize the video card for a real VGA mode. This function changes the first 16entries of the VGA palette. When the efifb driver kicks in, the palette is not restored to default ramp value, thus the 16 first entry remain in a modified state. The following patch prevent this corruption. Signed-off-by:

This cleans up a few bits in binfmt_elf.c and binfmts.h: - the hasvdso field in struct linux_binfmt is unused, so remove it and the only initialization of it - the elf_map CPP symbol is not defined anywhere in the kernel, so remove an unnecessary #ifndef elf_map - reduce excessive indentation in elf_format's initializer - add missing spaces, remove extraneous spaces No functional changes, but tested on x86 (32 and 64 bit), powerpc (32 and 64 bit), sparc64, arm, and alpha.
