2014-06-12blackfin: defconfigs: add MTD_SPI_NOR (new dependency for M25P80)Brian Norris7-9/+7
These defconfigs contain the CONFIG_M25P80 symbol, which is now dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to the relevant defconfigs. At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

2014-06-06blackfin/ptrace: call find_vma with the mmap_sem heldDavidlohr Bueso1-2/+6
Performing vma lookups without taking the mm->mmap_sem is asking for trouble. While doing the search, the vma in question can be modified or even removed before returning to the caller. Take the lock (shared) in order to avoid races while iterating through the vmacache and/or rbtree.

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA is not used by some architectures. Make pcibios_penalize_isa_irq() a __weak function to simplify the code.

2014-05-21ftrace: Make CALLER_ADDRx macros more genericAKASHI Takahiro1-10/+1
Most archs with HAVE_ARCH_CALLER_ADDR have pretty much the same definitions of CALLER_ADDRx(n). Instead of duplicating the code for all the archs, define a ftrace_return_address0() and ftrace_return_address(n) that can be overwritten by the archs if they need to do something different. Instead of 7 macros in every arch, we now only have at most 2 (and actually only 1 as ftrace_return_address0() should be the same for all archs). The CALLER_ADDRx(n) will now be defined in linux/ftrace.h and use the ftrace_return_address*(n?) macros. This removes a lot of the duplicate code.

It got a little delayed because I needed to wait for a dependency to be included (commit b424080a9e08: "reset: Add optional resets and stubs"). Plus, I had some email problems. All done now, the highlights are: - drivers can now deprecate their use of i2c classes. That shouldn't be used on embedded platforms anyhow and was often blindly copy&pasted. This mechanism gives users time to switch away and ultimately boot faster once the use of classes for those drivers is gone for good. - new drivers for QUP, Cadence, efm32 - tracepoint support for I2C and SMBus - bigger cleanups for the mv64xxx, nomadik, and designware drivers And the usual bugfixes, cleanups, feature additions.

That is, you can now trace some functions in one buffer, others in another buffer, all functions in a third buffer and so on. They are basically agnostic from each other.

2014-03-07ftrace: Do not pass data to ftrace_dyn_arch_initJiri Slaby1-1/+1
As the data parameter is not really used by any ftrace_dyn_arch_init, remove that from ftrace_dyn_arch_init. This also removes the addr local variable from ftrace_init which is now unused. Note the documentation was imprecise as it did not suggest to set (*data) to 0.

2014-03-07ftrace: Pass retval through return in ftrace_dyn_arch_init()Jiri Slaby1-3/+0
No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any way, it just sets the value to 0. And this is used as a return value in the caller -- ftrace_init, which just checks the retval against zero. Note there is also "return 0" in every ftrace_dyn_arch_init. So it is enough to check the retval and remove all the indirect sets of data on all archs.

This driver is for an old hardware and uses a deprecated Kernel internal API. If nobody cares enough to fix it, it would be removed on a couple Kernel releases - the sn9c102 driver was moved to staging. This driver was replaced by gspca, and disabled on some distros, as almost all devices are known to work properly with gspca. It should be removed from kernel on a couple Kernel releases - lots of driver fixes, improvements and cleanups * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (421 commits) [media] media: v4l2-dev: fix video device index assignment [media] rc-core: reuse device numbers [media] em28xx-cards: properly initialize the device bitmap [media] Staging: media: Fix line length exceeding 80 characters in as102_drv.c [media] Staging: media: Fix line length exceeding 80 characters in as102_fe.c [media] Staging: media: Fix quoted string split across line in as102_fe.c [media] media: st-rc: Add reset support [media] m2m-deinterlace: fix allocated struct type [media] radio-usb-si4713: fix sparse non static symbol warnings [media] em28xx-audio: remove needless check before usb_free_coherent() [media] au0828: Fix sparse non static symbol warning Revert "[media] go7007-usb: only use go->dev after allocated" [media] em28xx-audio: provide an error code when URB submit fails [media] em28xx: fix check for audio only usb interfaces when changing the usb alternate setting [media] em28xx: fix usb alternate setting for analog and digital video endpoints > 0 [media] em28xx: make 'em28xx_ctrl_ops' static em28xx-alsa: Fix error patch for init/fini [media] em28xx-audio: flush work at .fini [media] drxk: remove the option to load firmware asynchronously [media] em28xx: adjust period size at runtime ...

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

blackfin: bf60x: clock: return 0 upon error from clk_round_rate() clk_round_rate() should return 0 upon an error, rather than returning a negative error code. This is because clk_round_rate() is being changed to return an unsigned return type rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz.
