2012-10-09ARM: integrator: use __iomem pointers for MMIO, part 2Arnd Bergmann4-7/+7
Due to some interesting merges in the integrator code, not all users of mmio pointers were converted before, this fixes all warnings that got introduced as a consequence.

2012-10-09ARM: assabet: fix bogus warning in get_assabet_scr (again)Arnd Bergmann1-1/+1
Russell fixed this bogus warning before in 2f3eca8b4f "Shut up gcc warning in assabet.c", but apparently gcc has become smarter (or dumber) since 2005, and the same warning came up again. This uses the uninitialized_var() macro to convince gcc that the variable is actually being initialized. 100 times in fact. Without this patch, building assabet_defconfig results in: arch/arm/mach-sa1100/assabet.c: In function 'fixup_assabet': arch/arm/mach-sa1100/assabet.c:397:6: warning: 'scr' may be used uninitialized in this function [-Wuninitialized] arch/arm/mach-sa1100/assabet.c:389:16: note: 'scr' was declared here Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Russell King <rmk+kernel@arm.linux.org.uk>
2012-10-09ARM: shmobile: mark shmobile_init_late as __initArnd Bergmann1-1/+1
Patch 35f2b0bd59 "ARM: shmobile: Move definition of shmobile_init_late() to header" moved the definition of the shmobile_init_late function, but dropped the __init annotation, which is now causing warnings because the function calls shmobile_suspend_init, which is also marked init. Without this patch, building kota2_defconfig results in: WARNING: vmlinux.o(.text+0xb7c8): Section mismatch in reference from the function shmobile_init_late() to the function .init.text:shmobile_suspend_init() The function shmobile_init_late() references the function __init shmobile_suspend_init(). This is often because shmobile_init_late lacks a __init annotation or the annotation of shmobile_suspend_init is wrong. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Rafael J.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The first part of the media updates for Kernel 3.7. This series contain: - A major tree renaming patch series: now, drivers are organized internally by their used bus, instead of by V4L2 and/or DVB API, providing a cleaner driver location for hybrid drivers that implement both APIs, and allowing to cleanup the Kconfig items and make them more intuitive for the end user; - Media Kernel developers are typically very lazy with their duties of keeping the MAINTAINERS entries for their drivers updated. As now the tree is more organized, we're doing an effort to add/update those entries for the drivers that aren't currently orphan; - Several DVB USB drivers got moved to a new DVB USB v2 core; the new core fixes several bugs (as the existing one that got bitroted). Now, suspend/resume finally started to work fine (at least with some devices - we should expect more work with regards to it); - added multistream support for DVB-T2, and unified the API for DVB-S2 and ISDB-S. Backward binary support is preserved; - as usual, a few new drivers, some V4L2 core improvements and lots of drivers improvements and fixes. There are some points to notice on this series: 1) you should expect a trivial merge conflict on your tree, with the removal of Documentation/feature-removal-schedule.txt: this series would be adding two additional entries there. I opted to not rebase it due to this recent change; 2) With regards to the PCTV 520e udev-related breakage, I opted to fix it in a way that the patches can be backported to 3.5 even without your firmware fix patch. This way, Greg doesn't need to rush backporting your patch (as there are still the firmware cache and firmware path customization issues to be addressed there). I'll send later a patch (likely after the end of the merge window) reverting the rest of the DRX-K async firmware request, fully restoring its original behaviour to allow media drivers to initialize everything serialized as before for 3.7 and upper. 3) I'm planning to work on this weekend to test the DMABUF patches for V4L2. The patches are on my queue for several Kernel cycles, but, up to now, there is/was no way to test the series locally. I have some concerns about this particular changeset with regards to security issues, and with regards to the replacement of the old VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to GPU drivers change. The Overlay API allows direct PCI2PCI transfers from a media capture card into the GPU framebuffer, but its API is crappy. Also, the only existing X11 driver that implements it requires a XV extension that is not available anymore on modern drivers. The DMABUF can do the same thing, but with it is promising to be a properly-designed API. If I can successfully test this series and be happy with it, I should be asking you to pull them next week." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (717 commits) em28xx: regression fix: use DRX-K sync firmware requests on em28xx drxk: allow loading firmware synchrousnously em28xx: Make all em28xx extensions to be initialized asynchronously [media] tda18271: properly report read errors in tda18271_get_id [media] tda18271: delay IR & RF calibration until init() if delay_cal is set [media] MAINTAINERS: add Michael Krufky as tda827x maintainer [media] MAINTAINERS: add Michael Krufky as tda8290 maintainer [media] MAINTAINERS: add Michael Krufky as cxusb maintainer [media] MAINTAINERS: add Michael Krufky as lg2160 maintainer [media] MAINTAINERS: add Michael Krufky as lgdt3305 maintainer [media] MAINTAINERS: add Michael Krufky as mxl111sf maintainer [media] MAINTAINERS: add Michael Krufky as mxl5007t maintainer [media] MAINTAINERS: add Michael Krufky as tda18271 maintainer [media] s5p-tv: Report only multi-plane capabilities in vidioc_querycap [media] s5p-mfc: Fix misplaced return statement in s5p_mfc_suspend() [media] exynos-gsc: Add missing static storage class specifiers [media] exynos-gsc: Remove <linux/version.h> header file inclusion [media] s5p-fimc: Fix incorrect condition in fimc_lite_reqbufs() [media] s5p-tv: Fix potential NULL pointer dereference error [media] s5k6aa: Fix possible NULL pointer dereference ...

Without this patch, building mv78xx0_defconfig results in: WARNING: vmlinux.o(.text+0x15470): Section mismatch in reference from the function mv78xx0_timer_init() to the function .init.text:orion_time_init() The function mv78xx0_timer_init() references the function __init orion_time_init(). This is often because mv78xx0_timer_init lacks a __init annotation or the annotation of orion_time_init is wrong.

2012-10-07ARM: s3c24xx: fix multiple section mismatch warningsArnd Bergmann3-6/+6
The *_irq_add function should not be marked __init because the driver subsystem thinks they might be called at a later stage. The usb_simtec_init function accesses initdata and should be marked init. This is safe because the only caller is also an init function. Without this patch, building s3c2410_defconfig results in: WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1030): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add() The variable s3c2416_irq_interface references the function __init s3c2416_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1b08): Section mismatch in reference from the variable s3c2443_irq_interface to the function .init.text:s3c2443_irq_add() The variable s3c2443_irq_interface references the function __init s3c2443_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0xf44): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add() The variable s3c2416_irq_interface references the function __init s3c2416_irq_add() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/arm/mach-s3c24xx/built-in.o(.text+0x3f7c): Section mismatch in reference from the function usb_simtec_init() to the (unknown reference) .init.data:(unknown) The function usb_simtec_init() references the (unknown reference) __initdata (unknown).

Pull UAPI disintegration fixes from David Howells: "There are three main parts: (1) I found I needed some more fixups in the wake of testing Arm64 (some asm/unistd.h files had weird guards that caused problems - mostly in arches for which I don't have a compiler) and some __KERNEL__ splitting needed to take place in Arm64. (2) I found that c6x was missing some __KERNEL__ guards in its asm/signal.h. Mark Salter pointed me at a tree with a patch to remove that file entirely and use the asm-generic variant instead. (3) Lastly, m68k turned out to have a header installation problem due to it lacking a kvm_para.h file. The conditional installation bits for linux/kvm_para.h, linux/kvm.h and linux/a.out.h weren't very well specified - and didn't work if an arch didn't have the asm/ version of that file, but there *was* an asm-generic/ version. It seems the "ifneq $((wildcard ...),)" for each of those three headers in include/kernel/Kbuild is invoked twice during header installation, and the second time it matches on the just installed asm-generic/kvm_para.h file and thus incorrectly installs linux/kvm_para.h as well. Most arches actually have an asm/kvm_para.h, so this wasn't detectable in those." * 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers: UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k) c6x: remove c6x signal.h UAPI: Split compound conditionals containing __KERNEL__ in Arm64 UAPI: Fix the guards on various asm/unistd.h files c6x: make dsk6455 the default config

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull ADM Xen support from Konrad Rzeszutek Wilk: Features: * Allow a Linux guest to boot as initial domain and as normal guests on Xen on ARM (specifically ARMv7 with virtualized extensions). PV console, block and network frontend/backends are working. Bug-fixes: * Fix compile linux-next fallout. * Fix PVHVM bootup crashing. The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports ARMv7 platforms. The goal in implementing this architecture is to exploit the hardware as much as possible. That means use as little as possible of PV operations (so no PV MMU) - and use existing PV drivers for I/Os (network, block, console, etc). This is similar to how PVHVM guests operate in X86 platform nowadays - except that on ARM there is no need for QEMU. The end result is that we share a lot of the generic Xen drivers and infrastructure. Details on how to compile/boot/etc are available at this Wiki: http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions and this blog has links to a technical discussion/presentations on the overall architecture: http://blog.xen.org/index.php/2012/09/21/xensummit-sessions-new-pvh-virtualisation-mode-for-arm-cortex-a15arm-servers-and-x86/ * tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: (21 commits) xen/xen_initial_domain: check that xen_start_info is initialized xen: mark xen_init_IRQ __init xen/Makefile: fix dom-y build arm: introduce a DTS for Xen unprivileged virtual machines MAINTAINERS: add myself as Xen ARM maintainer xen/arm: compile netback xen/arm: compile blkfront and blkback xen/arm: implement alloc/free_xenballooned_pages with alloc_pages/kfree xen/arm: receive Xen events on ARM xen/arm: initialize grant_table on ARM xen/arm: get privilege status xen/arm: introduce CONFIG_XEN on ARM xen: do not compile manage, balloon, pci, acpi, pcpu and cpu_hotplug on ARM xen/arm: Introduce xen_ulong_t for unsigned long xen/arm: Xen detection and shared_info page mapping docs: Xen ARM DT bindings xen/arm: empty implementation of grant_table arch specific functions xen/arm: sync_bitops xen/arm: page.h definitions xen/arm: hypercalls ...

2012-10-06compat: move compat_siginfo_t definition to asm/compat.hDenys Vlasenko18-471/+513
This is a preparatory patch for the introduction of NT_SIGINFO elf note. Make the location of compat_siginfo_t uniform across eight architectures which have it. Now it can be pulled in by including asm/compat.h or linux/compat.h. Most of the copies are verbatim. compat_uid[32]_t had to be replaced by __compat_uid[32]_t. compat_uptr_t had to be moved up before compat_siginfo_t in asm/compat.h on a several architectures (tile already had it moved up). compat_sigval_t had to be relocated from linux/compat.h to asm/compat.h.

2012-10-06tile: fix personality bits handling upon exec()Jiri Kosina1-2/+2
Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch fixes tile architecture not to forcefully overwrite personality flags during exec(). In addition to that, we fix two other things along the way: - exec_domain switching is fixed -- set_personality() should always be used instead of directly assigning to current->personality. - as pointed out by Arnd Bergmann, PER_LINUX_32BIT is not used anywhere by tile, so let's just drop that in favor of PER_LINUX Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
