2009-06-19[ARM] Add old Feroceon support to compressed/head.SJoonyoung Shim
This patch supports the cache handling for some old Feroceon cores for which the CPU ID is like 0x41159260. This is a complement to commit ab6d15d50637fc25ee941710b23fed09ceb28db3. Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Nicolas Pitre <nico@marvell.com>
2009-06-19[ARM] 5559/1: Limit the stack unwinding caused by a kthread exitCatalin Marinas
When a kthread function returns, it branches to do_exit(). However, the unwinding information isn't valid anymore and any stack trace caused by do_exit() may be incorrect. This patch adds a kernel_thread_exit() function and annotated with '.cantunwind' so that the unwinder stops when reaching it.

2009-06-19[ARM] 5558/1: Add extra checks to ARM unwinder to avoid tracing corrupt stacksCatalin Marinas
There are situations where the unwinder goes beyond stack boundaries and unwinds random data. This patch moves the stack boundaries check after the unwind_exec_insn() call and adds an extra check for possible infinite loops (like "mov pc, lr" with pc == lr). The patch also fixes a bug in the unwind instructions interpreter. The 0xb0 instruction can only set PC to LR if this wasn't already set by a previous instruction (this is used on exceptions taken while in kernel mode where svc_entry is annotated with ".save {r0 - pc}").

2009-06-16[ARM] GTA02/FreeRunner: Add machine definitionAndy Green
This patch introduces the Openmoko GTA02 machine definition. Much of the code is based on Harald Welte's work, although it has been largely rewritten several times. This is intended to be the minimum machine definition to boot and be able to run a rootfs from NAND on GTA02 / FreeRunner. It does not bring up the framebuffer / Glamo and lacks many other peripheral drivers from outside the SoC. But once we have this basis in mainline kernel, we will be able to introduce the other drivers and add them here.

2009-06-16[ARM] S3C64XX: Initial support for DVFSMark Brown
This patch provides initial support for CPU frequency scaling on the Samsung S3C ARM processors. Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Use the regulator framework to provide optional support for DVFS in the S3C cpufreq driver. When a software controllable regulator is configured the driver will use it to lower the supply voltage when running at a lower frequency, giving improved power savings. When regulator support is disabled or no regulator can be obtained for VDDARM the driver will fall back to scaling only the frequency.

2009-06-16V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_linkGuennadi Liakhovetski
Currently pcm990 camera bus-width management functions request a GPIO and never free it again. With this approach the GPIO extender driver cannot be unloaded once camera drivers have been loaded, also unloading theb i2c-pxa bus driver produces errors, because the GPIO extender driver cannot unregister properly. Another problem is, that if camera drivers are once loaded before the GPIO extender driver, the platform code marks the GPIO unavailable and only a reboot helps to recover. Adding an explicit free_bus method and using it in mt9m001 and mt9v022 drivers fixes these problems.
