A misplaced #endif causes link errors related to pcim_*() functions. This is because pcim_*() functions are related to CONFIG_PCI option, however these are not related to CONFIG_HAS_IOPORT option. Therefore, when CONFIG_PCI is enabled and CONFIG_HAS_IOPORT is not enabled, it makes link errors related to pcim_*() functions as below: drivers/ata/libata-sff.c:3233: undefined reference to `pcim_iomap_regions' drivers/ata/libata-sff.c:3238: undefined reference to `pcim_iomap_table' drivers/built-in.o: In function `ata_pci_sff_init_host': drivers/ata/libata-sff.c:2318: undefined reference to `pcim_iomap_regions' drivers/ata/libata-sff.c:2329: undefined reference to `pcim_iomap_table Signed-off-by:

When taking an address of an extern array, gcc quite naturally should be able to say "an address of an object can never be NULL" and just optimize away the test entirely. However, the new alternate sysrq reset code (commit 154b7a48 : "Input: sysrq - allow specifying alternate reset sequence") did exactly that, and declared platform_sysrq_reset_seq[] as a weak array, and expecting that testing the address of the array would show whether it actually got linked against something or not. And that doesn't work with all gcc versions. Clearly it works with *some* versions of gcc, and maybe it's even supposed to work, but it really is a very fragile concept. So instead of testing the address of the weak variable, just create a weak instance of that array that is empty. If some platform then has a real platform_sysrq_reset_seq[] that overrides our weak one, the linker will switch to that one, and it all works without any run-time conditionals at all. Reported-by:

The stack vma is designed to grow automatically (marked with VM_GROWSUP or VM_GROWSDOWN depending on architecture) when an access is made beyond the existing boundary. However, particularly if you have not limited your stack at all ("ulimit -s unlimited"), this can cause the stack to grow even if the access was really just one past *another* segment. And that's wrong, especially since we first grow the segment, but then immediately later enforce the stack guard page on the last page of the segment. So _despite_ first growing the stack segment as a result of the access, the kernel will then make the access cause a SIGSEGV anyway! So do the same logic as the guard page check does, and consider an access to within one page of the next segment to be a bad access, rather than growing the stack to abut the next segment.

In the optimization category, we fixed a performance regression in the jbd2 layer introduced by commit d9b01934 ("jbd: fix fsync() tid wraparound bug", introduced in v3.0) which shows up in the AIM7 benchmark. We also further optimized jbd2 by minimize the amount of time that transaction handles are held active.

Pull PWM changes from Thierry Reding: "A new driver has been added to support the PWM mode of the timer counter blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained suspend and resume functionality. User drivers can now query the core for whether access to a PWM device will sleep (if the PWM chip is on a slow bus such as I2C or SPI). The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state in addition to the FB layer's blanking states. To round things off, a few fixes and cleanups are also included" * tag 'for-3.9-rc1' of git://gitorious.org/linux-pwm/linux-pwm: pwm: twl: Use to_twl() instead of container_of() pwm: tegra: assume CONFIG_OF pwm_backlight: Validate dft_brightness in main probe function pwm: Export pwm_{set,get}_chip_data() pwm: Make Kconfig entries more consistent pwm: Add can_sleep property to drivers pwm: Add pwm_can_sleep() as exported API to users pwm-backlight: handle BL_CORE_FBBLANK state pwm: pwm-tiecap: Low power sleep support pwm: pwm-tiehrpwm: Low power sleep support pwm: pwm-tiehrpwm: Update the clock handling of pwm-tiehrpwm driver pwm: vt8500: Add polarity support pwm: vt8500: Register write busy test performed incorrectly pwm: atmel: add Timer Counter Block PWM driver

Pull MMC update from Chris Ball: "MMC highlights for 3.9: Core: - Support for packed commands in eMMC 4.5. (This requires a host capability to be turned on. It increases write throughput by 20%+, but may also increase average write latency; more testing needed.) - Add DT bindings for capability flags. - Add mmc_of_parse() for shared DT parsing between drivers.

Make it drop the pde in *all* cases when no new reference to it is put into an inode - both when an inode had already been set up (as we were already doing) and when inode allocation has failed. Makes for simpler logics in callers... Signed-off-by:

If proc_get_inode() succeeded, but d_make_root() failed, pde_put() for proc_root will be called twice: the first time due to iput() called from d_make_root() and the second time directly in the end of proc_fill_super(). Signed-off-by:

According to SUSv3: [EACCES] Permission denied. An attempt was made to access a file in a way forbidden by its file access permissions. [EPERM] Operation not permitted. An attempt was made to perform an operation limited to processes with appropriate privileges or to the owner of a file or other resource. So -EPERM should be returned if capability checks fails. Strictly speaking this is an API change since the error code user sees is altered. Signed-off-by:

Running AIO is pinning inode in memory using file reference. Once AIO is completed using aio_complete(), file reference is put and inode can be freed from memory. So we have to be sure that calling aio_complete() is the last thing we do with the inode. Signed-off-by:
