2010-07-01ARM: 6188/1: Add a config option for the ARM11MPCore DMA cache maintenance ↵Catalin Marinas
workaround Commit f4d6477f introduced a workaround for the lack of hardware broadcasting of the cache maintenance operations on ARM11MPCore. However, the workaround is only valid on CPUs that do not do speculative loads into the D-cache. This patch adds a Kconfig option with the corresponding help to make the above clear. When the DMA_CACHE_RWFO option is disabled, the kernel behaviour is that prior to the f4d6477f commit. This also allows ARMv6 UP processors with speculative loads to work correctly. For other processors, a different workaround may be needed.

2010-07-01ARM: 6187/1: The v6_dma_inv_range() function must preserve data on SMPCatalin Marinas
A recent patch for DMA cache maintenance on ARM11MPCore added a write for ownership trick to the v6_dma_inv_range() function. Such operation destroys data already present in the buffer. However, this function is used with with dma_sync_single_for_device() which is supposed to preserve the existing data transfered into the buffer. This patch adds a combination of read/write for ownership to preserve the original data.

2010-06-16OMAP4: clock: Fix multi-omap boot with reset un-used clocksSantosh Shilimkar
This patch uses "ENABLE_ON_INIT" flag on the emif clock nodes to avoid the emif clk getting cut as part of reset un-used clock routine which prevents boot. Since "omap4xxx_clk_init()" calls "clk_enable_init_clocks()" which increases the usecount on all ENABLE_ON_INIT clocks, it prevents "omap2_clk_disable_unused()" from disabling the clock. The real fix is to have driver for EMIF and do clock get/enable as part of it. The EMIF driver is planned to be done HWMOD way so till that available to keep omap3_defconfig booting on OMAP4430, this patch is necessary.

When going to standby mode mpc code maps the whole soc5200 node to access warious MBAR registers. However as of_iomap uses 'reg' property of device node, only small part of MBAR is getting mapped. Thus pm code gets oops when trying to access high parts of MBAR. As a way to overcome this, make mpc52xx_pm_prepare() explicitly map whole MBAR (0xc0000).

When trying to flash a machine via the update_flash command, Anton received the following error: Restarting system. FLASH: kernel bug...flash list header addr above 4GB The code in question has a comment that the flash list should be in the kernel data and therefore under 4GB: /* NOTE: the "first" block list is a global var with no data * blocks in the kernel data segment. We do this because * we want to ensure this block_list addr is under 4GB. */ Unfortunately the Kconfig option is marked tristate which means the variable may not be in the kernel data and could be above 4GB. Instead of relying on the data segment being below 4GB, use the static data buffer allocated by the kernel for use by rtas. Since we don't use the header struct directly anymore, convert it to a simple pointer.

However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily valid and we overrun the array; spurious "cpu is not possible, ignoring" errors result.

2010-06-15powerpc: Move kdump default base address to 64MB on 64bitAnton Blanchard
We are seeing boot fails on some System p machines when using the kdump crashkernel= boot option. The default kdump base address is 32MB, so if we reserve 256MB for kdump then we reserve all of the RMO except the first 32MB. We really want kdump to reserve some memory in the RMO and most of it elsewhere but that will require more significant changes. For now we can shift the default base address to 64MB when CONFIG_PPC64 and CONFIG_RELOCATABLE are set. This isn't quite correct since what we really care about is the kdump kernel is relocatable, but we already make the assumption that base kernel and kdump kernel have the same CONFIG_RELOCATABLE setting, eg: #ifndef CONFIG_RELOCATABLE if (crashk_res.start != KDUMP_KERNELBASE) printk("Crash kernel location must be 0x%x\n", KDUMP_KERNELBASE); ... RTAS is instantiated towards the top of our RMO, so if we were to go any higher we risk not having enough RMO memory for the kdump kernel on boxes with a 128MB RMO.

2010-06-11PCI: clear bridge resource range if BIOS assigned bad oneYinghai Lu
Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior.

2010-06-10OMAP3: PM: fix IO daisy chain enable to use PM_WKEN regKevin Hilman
Checking to se if the IO daisy chain is enabled should be checking the PM_WKEN register, not the PM_WKST register. Reading PM_WKST tells us if an event occurred, not whether or not it is enabled. Apparently, we've been lucky until now in that a pending event has not been there during enable. However, on 3630/Zoom3, I noticed because of the WARN that this timeout was always happening.

2010-06-10omap: GPIO: fix auto-disable of debounce clockKevin Hilman
The addition of the new debounce code (commit 168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of debounce clocks on idle by forgetting to update the debounce clock enable mask. Add back the updating of bank->dbck_enable_mask so debounce clocks are auto-disabled. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-06-10omap: DMTIMER: Ack pending interrupt always when stopping a timerTero Kristo
The kernel timer queue is being run currently from a GP timer running in a one shot mode, which works in a way that when it expires, it will also stop. Usually during this situation, the interrupt handler will ack the interrupt, load a new value to the timer and start it again. During suspend, the situation is slightly different, as we disable interrupts just before timekeeping is suspended, which leaves a small window where the timer can expire before it is stopped, and will leave the interrupt flag pending. This pending interrupt will prevent ARM sleep entry, thus now we ack it always when we are attempting to stop a timer.
