Not paying attention to the value being set is a bad thing because it means that we'll not set the hardware up to reflect what was requested.

2012-07-05gpio/msm_v1: CONFIG_GPIO_MSM_V1 is only available on three SoCsChristian Dietrich
The feature GPIO_MSM_V1 is only available on three SoCs. On all other MSM SoCs the INT_GPIO_GROUP{1,2} is undeclared, but Kconfig does allow such configurations. Therefore the produced configuration is valid, but does not compile. The problem is fixed by adding the missing Kconfig constraints. drivers/gpio/gpio-msm-v1.c: In function ‘msm_init_gpio’: drivers/gpio/gpio-msm-v1.c:629:26: error: 'INT_GPIO_GROUP1' undeclared drivers/gpio/gpio-msm-v1.c:630:26: error: 'INT_GPIO_GROUP2' undeclared Signed-off-by: Christian Dietrich <christian.dietrich@informatik.uni-erlangen.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

'sub pc, pc, #1b-2b+8-2' results in address<1:0> == '10'. sub pc, pc, #const (== ADR pc, #const) performs an interworking branch (BXWritePC()) on ARMv7+ and a simple branch (BranchWritePC()) on earlier versions.

2012-07-05ARM: 7443/1: Revert "new way of handling ERESTART_RESTARTBLOCK"Will Deacon
This reverts commit 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252. Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.

2012-07-05aio: make kiocb->private NUll in init_sync_kiocb()Junxiao Bi
Ocfs2 uses kiocb.*private as a flag of unsigned long size. In commit a11f7e6 ocfs2: serialize unaligned aio, the unaligned io flag is involved in it to serialize the unaligned aio. As *private is not initialized in init_sync_kiocb() of do_sync_write(), this unaligned io flag may be unexpectly set in an aligned dio. And this will cause OCFS2_I(inode)->ip_unaligned_aio decreased to -1 in ocfs2_dio_end_io(), thus the following unaligned dio will hang forever at ocfs2_aiodio_wait() in ocfs2_file_aio_write().

2012-07-04Input: request threaded-only IRQs with IRQF_ONESHOTLars-Peter Clausen
Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.

aess IP blocks The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special programming for them to enter idle. Without this programming, they will prevent the rest of the chip from entering full chip idle. To implement the idle programming cleanly, this will take some coordination between maintainers. This is likely to take some time, so it is probably best to leave this for 3.6 or 3.7. So, in the meantime, prevent these IP blocks from being registered. Later, once the appropriate support is available, this patch can be reverted. This second version comments out the IP block data since Benoît didn't like removing it.

2012-07-04rpmsg: make sure inflight messages don't invoke just-removed callbacksOhad Ben-Cohen
When inbound messages arrive, rpmsg core looks up their associated endpoint (by destination address) and then invokes their callback. We've made sure that endpoints will never be de-allocated after they were found by rpmsg core, but we also need to protect against the (rare) scenario where the rpmsg driver was just removed, and its callback function isn't available anymore. This is achieved by introducing a callback mutex, which must be taken before the callback is invoked, and, obviously, before it is removed.

2012-07-04rpmsg: avoid premature deallocation of endpointsOhad Ben-Cohen
When an inbound message arrives, the rpmsg core looks up its associated endpoint and invokes the registered callback. If a message arrives while its endpoint is being removed (because the rpmsg driver was removed, or a recovery of a remote processor has kicked in) we must ensure atomicity, i.e.: - Either the ept is removed before it is found or - The ept is found but will not be freed until the callback returns This is achieved by maintaining a per-ept reference count, which, when drops to zero, will trigger deallocation of the ept. With this in hand, it is now forbidden to directly deallocate epts once they have been added to the endpoints idr.

2012-07-04tools lib traceevent: Introduce extend_token()Namhyung Kim
The __read_token() function has some duplicated code to handle internal buffer overflow. Factor them out to new extend_token(). According to the man pages of realloc/free(3), they can handle NULL pointer input so that it can be ended up to compact the code. Also handle error path correctly.

2012-07-04tools lib traceevent: Fix trace_printk for long integersWolfgang Mauerer
On 32 bit systems, a conversion of the trace_printk format string "%lu" -> "%llu" is intended (similar for %lx etc.) when a trace was taken on a machine with 64 bit long integers. However, the current code computes the bogus transformation "%lu" -> "%u". Fix this. Besides that, the transformation is only required on systems that don't use 64 bits for long integers natively.
