| * ARM: 7912/1: check stack pointer in get_wchanKonstantin Khlebnikov2013-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_wchan() is lockless. Task may wakeup at any time and change its own stack, thus each next stack frame may be overwritten and filled with random stuff. /proc/$pid/stack interface had been disabled for non-current tasks, see [1] But 'wchan' still allows to trigger stack frame unwinding on volatile stack. This patch fixes oops in unwind_frame() by adding stack pointer validation on each step (as x86 code do), unwind_frame() already checks frame pointer. Also I've found another report of this oops on stackoverflow (irony).

| | | | | | | | | | | | | | | | | | | | | | | | | | Current code is using PHYS_OFFSET to calculate the arm_dma_limit which will lead to wrong calculations in cases where PHYS_OFFSET is updated runtime.

| * ARM: another fix for the DMA mapping checksRussell King2013-12-09
| | | | | | | | | | | | | | | | | | | | | | | | Peter reports that OMAP audio broke with the recent fix for these checks, caused by OMAP audio using a 64-bit DMA mask. We should allow 64-bit DMA masks even with 32-bit dma_addr_t if we can be sure the amount of RAM we have won't allow the 32-bit dma_addr_t to overflow. Unfortunately, the checks to detect overflow were not correct. Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Erratum 71 of PXA270M Processor Family Specification Update (April 19, 2010) explains that watchdog reset time is just 8us insead of 10ms in EMTS. If SDRAM is not reset, it causes memory bus congestion and the device hangs. We put SDRAM in selfresh mode before watchdog reset, removing potential freezes. Without this patch PXA270-based ICP DAS LP-8x4x hangs after up to 40 reboots. With this patch it has successfully rebooted 500 times.

* | ARM: OMAP2+: omap_device: add fail hook for runtime_pm when bad data is detectedNishanth Menon2013-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the cross dependencies between hwmod for automanaged device information for OMAP and dts node definitions, we can run into scenarios where the dts node is defined, however it's hwmod entry is yet to be added. In these cases: a) omap_device does not register a pm_domain (since it cannot find hwmod entry). b) driver does not know about (a), does a pm_runtime_get_sync which never fails c) It then tries to do some operation on the device (such as read the revision register (as part of probe) without clock or adequate OMAP generic PM operation performed for enabling the module. This causes a crash such as that reported in: https://bugzilla.kernel.org/show_bug.cgi?id=66441 When 'ti,hwmod' is provided in dt node, it is expected that the device will not function without the OMAP's power automanagement. Hence, when we hit a fail condition (due to hwmod entries not present or other similar scenario), fail at pm_domain level due to lack of data, provide enough information for it to be fixed, however, it allows for the driver to take appropriate measures to prevent crash.

This is true for OMAP3 like platforms that have RESET_DONE status in the SYSSTATUS register and so the the SOFTRESET bit in SYSCONFIG is not automatically cleared. It is not a problem for OMAP4 like platforms that indicate RESET completion by clearing the SOFTRESET bit in the SYSCONFIG register. This repeated SOFTRESET is undesired and was the root cause of USB host issues on OMAP3 platforms when hwmod was allowed to do the SOFTRESET for the USB Host module. To fix this we clear the SOFTRESET bit and update the sysconfig register + sysc_cache using write_sysconfig().

Also a fix for a regression where we now are wrongly trying to initialize devices on secure omaps like n900 and n9* when booted using device tree. We need to set aes, sham and timer12 to disabled mode for secure devices as they are claimed by the firmware running in the secure mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The am3517 is wrongly booting as omap3 which means that the am3517 specific devices like Ethernet won't work when booted with device tree. Now with the new devices defined in am3517.dtsi, let's use that instead of the omap3.dtsi, and add a separate machine entry for am3517 so am3517-evm can use it.

| * | | ARM: OMAP2+: Fix overwriting hwmod data with data from device treeTony Lindgren2013-12-06

So they should all be fixed up to be separate devices in the .dts files. We also have the related data removed for at least omap4 in commit 3b9b10151c68 (ARM: OMAP4: hwmod data: Clean up the data file), so that data is wrongly initialized as null data. So we need to fix two bugs: 1. We are only checking the first entry of the ti,hwmods property This means that we're only initializing the first hwmods entry instead of the ones listed in the ti,hwmods property. 2. We are only checking the child nodes, not the nodes themselves This means that anything listed at OCP level is currently just ignored and unitialized and at least the omap4 case, with the legacy data missing from the hwmod. Fix both of the issues by using an index to the ti,hwmods property and changing the hwmod lookup function to also check the current node for ti,hwmods property instead of just the children. While at it, let's also add some warnings for the bad data so it's easier to fix.

Tony thinks this was the last major set of fixes, with maybe just a few small patches to follow. - More fixes for Marvell platforms, most dealing with misdescribed PCIe hardware, i.e. incorrect number of busses on some SoCs, etc. The line delta adds up due to various ranges moving around when this is fixed.

So it was reverted (commit b7a8ca5 (ARM: at91: rm9200 fix time support)) which stopped the oops from happening because min_delta_ns is increased by one in arch code which stopped from problem from happening. Now that the timer core problem is fixed (commit a4578ea (clockevents: Sanitize ticks to nsec conversion)), we can switch back to the clockevents_config_and_register helper.
