2011-11-08MIPS: Kernel hangs occasionally during boot.Al Cooper
The Kernel hangs occasionally during boot after "Calibrating delay loop..". This is caused by the c0_compare_int_usable() routine in cevt-r4k.c returning false which causes the system to disable the timer and hang later. The false return happens because the routine is using a series of four calls to irq_disable_hazard() as a delay while it waits for the timer changes to propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the series of irq_disable_hazard() calls turn into ehb instructions and can take as little as a few clock ticks for all 4 instructions. This is not enough of a delay, so the routine thinks the timer is not working. This fix uses up to a max number of cycle counter ticks for the delay and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the hazard condition between cp0 writes and cp0 reads.

2011-11-08x86/mce: Make mce_chrdev_ops 'static const'Luck, Tony
Arjan would like to make struct file_operations const, but mce-inject directly writes to the mce_chrdev_ops to install its write handler. In an ideal world mce-inject would have its own character device, but we have a sizable legacy of test scripts that hardwire "/dev/mcelog", so it would be painful to switch to a separate device now. Instead, this patch switches to a stub function in the mce code, with a registration helper that mce-inject can call when it is loaded. Note that this would also allow for a sane process to allow mce-inject to be unloaded again (with an unregister function, and appropriate module_{get,put}() calls), but that is left for potential future patches.

2011-11-08ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in ↵Archit Taneja
bootloader Resetting DISPC when a DISPC output is enabled causes the DSS to go into an inconsistent state. Thus if the bootloader has enabled a display, the hwmod code cannot reset the DISPC module just like that, but the outputs need to be disabled first. Add function dispc_disable_outputs() which disables all active overlay manager and ensure all frame transfers are completed. Modify omap_dss_reset() to call this function and clear DSS_CONTROL, DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the DSS2 driver starts. This resolves the hang issue(caused by a L3 error during boot) seen on the beagle board C3, which has a factory bootloader that enables display. The issue is resolved with this patch. Thanks to Tomi and Sricharan for some additional testing.

2011-11-08ARM: OMAP: HWMOD: Unify DSS resets for OMAPsTomi Valkeinen
This patch adds a custom DSS reset function used on OMAPs from OMAP2 forward. The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.

The OMAP4 HWMOD data currently contains errors with DSS clocks: dss_hdmi and dss_venc have their main_clks wrong. The clocks should be dss_48mhz_clk and dss_tv_clk, respectively. These problems were temporarily fixed with the DSS patches 9ede365aa6f74428a1f69c21ca1cf21213167576 ("HACK: OMAP: DSS2: clk hack for OMAP2/3"), and df5d3ed23cf73ee0763a8963003bda9b69d9620f ("OMAP: DSS2: HDMI: fix hdmi clock name"), which can be reverted after this patch.

2011-11-08ARM: OMAP4: HWMOD: Add HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_coreTomi Valkeinen
DSS needs all DSS clocks to be enabled to be able to finish reset properly. Before v3.1-rc1 the omapdss driver was managing clocks and resets correctly. However, when omapdss started using runtime PM at v3.1-rc1, the responsibility for the reset moved to HWMOD framework. HWMOD framework does not currently enable all the DSS clocks when resetting the DSS hardware. This causes the HWMOD frameworks boot-time reset to fail, possibly leaving the DSS hardware in undefined state. This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag is actually not used on OMAP4, because dss_core hardware does not have soft-reset functionality and thus the HWMOD framework never resets nor waits for the reset to finish. However, while the flag is not strictly needed currently, I think it represents the HW correctly: all the DSS clocks should be enabled after power-on to allow DSS hardware to finish its reset. A custom reset function will be added in the following patches which manages this correctly for OMAP4.

2011-11-06cpuidle: Single/Global registration of idle statesDeepthi Dharwar
This patch makes the cpuidle_states structure global (single copy) instead of per-cpu. The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.

2011-11-06cpuidle: Split cpuidle_state structure and move per-cpu statistics fieldsDeepthi Dharwar
This is the first step towards global registration of cpuidle states. The statistics used primarily by the governor are per-cpu and have to be split from rest of the fields inside cpuidle_state, which would be made global i.e. single copy. The driver_data field is also per-cpu and moved.
