2012-04-24pinctrl: fix signed vs unsigned conditionals inside pinmux_map_to_settingJohn Crispin
pinmux_map_to_setting() uses setting->data.mux.func/group to store the return code of pinmux_func_name_to_selector/pinctrl_get_group_selector(). However, struct pinctrl_setting_mux defines these elements as unsigned, resulting in all error codes getting lost. The conditionals following the assignments will always evaluate to false thus breaking the error paths. This bug can be triggered by loading a pinmux group map from the devicetree with an invalid function/group string.

2012-04-18pinctrl: replace list_*() with get_*_count()Viresh Kumar
Most of the SoC drivers implement list_groups() and list_functions() routines for pinctrl and pinmux. These routines continue returning zero until the selector argument is greater than total count of available groups or functions. This patch replaces these list_*() routines with get_*_count() routines, which returns the number of available selection for SoC driver. pinctrl layer will use this value to check the range it can choose. This patch fixes all user drivers for this change. There are other routines in user drivers, which have checks to check validity of selector passed to them. It is also no more required and hence removed. Documentation updated as well.

2012-04-16x86-32: fix up strncpy_from_user() sign errorLinus Torvalds
The 'max' range needs to be unsigned, since the size of the user address space is bigger than 2GB. We know that 'count' is positive in 'long' (that is checked in the caller), so we will truncate 'max' down to something that fits in a signed long, but before we actually do that, that comparison needs to be done in unsigned. Bug introduced in commit 92ae03f2ef99 ("x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). On x86-64 you can't trigger this, since the user address space is much smaller than 63 bits, and on x86-32 it works in practice, since you would seldom hit the strncpy limits anyway. I had actually tested the corner-cases, I had only tested them on x86-64. Besides, I had only worried about the case of a pointer *close* to the end of the address space, rather than really far away from it ;) This also changes the "we hit the user-specified maximum" to return 'res', for the trivial reason that gcc seems to generate better code that way. 'res' and 'count' are the same in that case, so it really doesn't matter which one we return. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-04-15ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEEJonathan Austin
Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE register states are not saved/restored at context switch. The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

If cpu0 then decides to schedule something on cpu1 and wait for it to complete, before cpu0 has set cpu1 active, we have a deadlock.

2012-04-15PCI: Fix regression in pci_restore_state(), v3Rafael J. Wysocki
Commit 26f41062f28d ("PCI: check for pci bar restore completion and retry") attempted to address problems with PCI BAR restoration on systems where FLR had not been completed before pci_restore_state() was called, but it did that in an utterly wrong way. First off, instead of retrying the writes for the BAR registers only, it did that for all of the PCI config space of the device, including the status register (whose value after the write quite obviously need not be the same as the written one). Second, it added arbitrary delay to pci_restore_state() even for systems where the PCI config space restoration was successful at first attempt. Finally, the mdelay(10) it added to every iteration of the writing loop was way too much of a delay for any reasonable device. All of this actually caused resume failures for some devices on Mikko's system. To fix the regression, make pci_restore_state() only retry the writes for BAR registers and only wait if the first read from the register doesn't return the written value. Additionaly, make it wait for 1 ms, instead of 10 ms, after every failing attempt to write into config space. Reported-by: Mikko Vinni <mmvinni@yahoo.com> Signed-off-by: Rafael J.

2012-04-14do not export kernel's NULL #define to userspaceLubos Lunak
GCC's NULL is actually __null, which allows detecting some questionable NULL usage and warn about it. Moreover each platform/compiler should have its own stddef.h anyway (which is different from linux/stddef.h). So there's no good reason to leak kernel's NULL to userspace and override what the compiler provides.

2012-04-14ARM: EXYNOS: Remove broken config values for touchscren for NURI boardMarek Szyprowski
The atmel_mxt_ts driver has been extended to support more 'configuration objects' in commit 81c88a711 ("Input: atmel_mxt_ts - update object list"), what broke the configuration values for NURI board. These values are optional anyway, so remove them to get the driver working correctly.

2012-04-14ARM: EXYNOS: set fix xusbxti clock for NURI and Universal210 boardsMarek Szyprowski
On some versions of NURI and UniversalC210 boards, camera clocks are routed directly to xusbxti clock source. This patch sets the correct value for this clock to let usb and camera sensors to work correctly and avoid division by zero on driver's probe.
