2012-01-23ARM: 7289/1: vmlinux.lds.S: do not hardcode cacheline size as 32 bytesWill Deacon
The linker script assumes a cacheline size of 32 bytes when aligning the .data..cacheline_aligned and .data..percpu sections. This patch updates the script to use L1_CACHE_BYTES, which should be set to 64 on platforms that require it.

2012-01-20ARM: clean up idle handlersNicolas Pitre
Let's factor out the need_resched() check instead of having it duplicated in every pm_idle implementations to avoid inconsistencies (omap2_pm_idle is missing it already). The forceful re-enablement of IRQs after pm_idle has returned can go. The warning certainly doesn't trigger for existing users. To get rid of the pm_idle calling convention oddity, let's introduce arm_pm_idle() allowing for the local_irq_enable() to be factored out from SOC specific implementations. The default pm_idle function becomes a wrapper for arm_pm_idle and it takes care of enabling IRQs closer to where they are initially disabled. And finally move the comment explaining the reason for that turning off of IRQs to a more proper location.

2012-01-20Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp ↵Russell King
bus." This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register.

2012-01-20ARM: at91: fix at91rm9200 soc subtype handlingNicolas Ferre
Currently setting it to PQFP changes subtype to BGA as subtypes are swapped in at91rm9200_set_type(). Wrong subtype causes GPIO bank D not to work at all. After this fix, subtype is still set as unknown. But board code should fill it in with proper value. Another information is thus printed.
