git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup From Tony Lindgren: Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>: This series removes the currently-unused PRCM macros from arch/arm/mach-omap2. Basic test logs are available at: http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/ Once, years ago, we thought that it would be good to document the PRCM register bits in the Linux codebase. Most folks in the broader community did not have access to the same documentation, so we thought that they might be able to use these bits to fix bugs and improve the code. We were also able to autogenerate most of these macros, so it was thought that defining them in advance would reduce the risk of error, inconsistencies, and merge conflicts caused when patch sets incrementally defined them by hand. Well, nice thoughts. But the first rationale was rendered partially obsolete when TI started to release public TRM documentation PDFs at some point in the OMAP3 timeframe. (Despite their weaknesses, TI's public OMAP TRMs remain the most useful public documentation available for any ARM Linux SoC -- at least to the extent of my knowledge.) And then the current Linux development tropism towards development-by-negative-diffstat obliterated the remainder of the above two philosophies. So, for the few, the masochistic, out there who wish to continue developing TI PRCM code, I would ask that you resurrect any additionally-needed macros from these commits, rather than writing them manually. Purely for the sake of a pleasant atavism, perhaps; the way one appreciates a used bookstore, or a video rental store... And thanks to the upstream maintainers for being patient while we adjust. * tag 'omap-for-v3.12/cleanup-unused-defines' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP5: PRM/CM: Cleanup unused header ARM: OMAP4: PRM/CM: Cleanup unused header ARM: OMAP3: PRM/CM: Cleanup unused header ARM: OMAP2: PRM/CM: Cleanup unused header Signed-off-by: Olof Johansson <olof@lixom.net>

The "nop" driver isn't a do-nothing-stub but supports a couple functions like clock on/off or is able to use a voltage regulator.

2013-08-06ARM: msm: Only compile io.c on platforms that use itStephen Boyd1-4/+4
Only the non-dt based MSM platforms need to map memory from their machine descriptor. Unfortunately it is always compiled if ARCH_MSM=y and the file also has mach/ includes in it. Since dt-based MSM platforms aren't actually using anything in this file just compile io.c on the non-dt based MSM platforms.

Since we don't currently have DT bindings in place for the MSM iommu driver just remove this file for the time being.

Pull ARM fixes from Russell King: "I've thought long and hard about what to say for this pull request, and I really can't work out anything sane to say to summarise much of these commits. The problem is, for most of these are, yet again, lots of small bits scattered around the place without any real overall theme to them" Most notable is probably the kuser page helper improvements. * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: (22 commits) ARM: Add .text annotations where required after __CPUINIT removal ARM: 7803/1: Fix deadlock scenario with smp_send_stop() ARM: make vectors page inaccessible from userspace ARM: move signal handlers into a vdso-like page ARM: allow kuser helpers to be removed from the vector page ARM: update FIQ support for relocation of vectors ARM: use linker magic for vectors and vector stubs ARM: move vector stubs ARM: poison memory between kuser helpers ARM: poison the vectors page ARM: 7801/1: v6: prevent gcc 4.5 from reordering extended CP15 reads above is_smp() test ARM: 7800/1: ARMv7-M: Fix name of NVIC handler function ARM: Fix sorting of machine- initializers ARM: 7791/1: a.out: remove partial a.out support ARM: 7790/1: Fix deferred mm switch on VIVT processors ARM: 7789/1: Do not run dummy_flush_tlb_a15_erratum() on non-Cortex-A15 ARM: 7787/1: virt: ensure visibility of __boot_cpu_mode ARM: 7788/1: elf: fix lpae hwcap feature reporting in proc/cpuinfo ARM: 7786/1: hyp: fix macro parameterisation ARM: 7785/1: mm: restrict early_alloc to section-aligned memory ...
2013-08-03ARM: imx: fix mismerge of localtimer codeOlof Johansson1-1/+0
I mis-resolved a merge conflict due to the branch being a bit on the old side, Stephen noticed. Here's the fix. Reported-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Olof Johansson <olof@lixom.net>
2013-08-03ARM: OMAP2+: Fix fallout from localtimer divorce and SMP=nStephen Boyd1-0/+7
A recent patch ef3160c (ARM: OMAP2+: Divorce from local timer API, 2013-03-04) broke the omap build when SMP=n because the TWD functions are only compiled on SMP=y builds. Stub out the TWD calls when the TWD isn't built in to to keep everything building. arch/arm/mach-omap2/built-in.o: In function `omap4_local_timer_init': dss-common.c:(.init.text+0x1d90): undefined reference to `twd_local_timer_register' Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Olof Johansson <olof@lixom.net>

2013-08-01ARM: Add .text annotations where required after __CPUINIT removalRussell King2-0/+2
Commit 8bd26e3a7 (arm: delete __cpuinit/__CPUINIT usage from all ARM users) caused some code to leak into sections which are discarded through the removal of __CPUINIT annotations. Add appropriate .text annotations to bring these back into the kernel text. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-08-01ARM: 7803/1: Fix deadlock scenario with smp_send_stop()Stephen Boyd1-0/+3
If one process calls sys_reboot and that process then stops other CPUs while those CPUs are within a spin_lock() region we can potentially encounter a deadlock scenario like below. CPU 0 CPU 1 ----- ----- spin_lock(my_lock) smp_send_stop() <send IPI> handle_IPI() disable_preemption/irqs while(1); <PREEMPT> spin_lock(my_lock) <--- Waits forever We shouldn't attempt to run any other tasks after we send a stop IPI to a CPU so disable preemption so that this task runs to completion. We use local_irq_disable() here for cross-arch consistency with x86.

2013-08-01ARM: make vectors page inaccessible from userspaceRussell King3-1/+12
If kuser helpers are not provided by the kernel, disable user access to the vectors page. With the kuser helpers gone, there is no reason for this page to be visible to userspace. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-08-01ARM: move signal handlers into a vdso-like pageRussell King6-31/+87
Move the signal handlers into a VDSO page rather than keeping them in the vectors page. This allows us to place them randomly within this page, and also map the page at a random location within userspace further protecting these code fragments from ROP attacks. The new VDSO page is also poisoned in the same way as the vector page. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-08-01ARM: allow kuser helpers to be removed from the vector pageRussell King3-9/+51
Provide a kernel configuration option to allow the kernel user helpers to be removed from the vector page, thereby preventing their use with ROP (return orientated programming) attacks. This option is only visible for CPU architectures which natively support all the operations which kernel user helpers would normally provide, and must be enabled with caution.
