* ARM: 7629/1: mm: Fix missing XN flag for for MT_MEMORY_SOSantosh Shilimkar2013-01-191-1/+1
| | | | | | | | | | | Commit 8fb54284ba6a {ARM: mm: Add strongly ordered descriptor support} added XN flag at section level but missed it at PTE level. Fix it by adding the L_PTE_XN to MT_MEMORY_SO PTE descriptor.

* ARM: DMA: Fix struct page iterator in dma_cache_maint() to work with sparsememRussell King2013-01-191-8/+10
| | | | | | | | | | | | | | | | | | | Subhash Jadavani reported this partial backtrace: Now consider this call stack from MMC block driver (this is on the ARMv7 based board): [<c001b50c>] (v7_dma_inv_range+0x30/0x48) from [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c) [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c) from [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c) [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c) from [<c0017ff8>] (dma_map_sg+0x3c/0x114) This is caused by incrementing the struct page pointer, and running off the end of the sparsemem page array. Fix this by incrementing by pfn instead, and convert the pfn to a struct page.

* ARM: 7628/1: head.S: map one extra section for the ATAG/DTB areaNicolas Pitre2013-01-161-0/+3
| | | | | | | | | | | | | | | | | We currently use a temporary 1MB section aligned to a 1MB boundary for mapping the provided device tree until the final page table is created. However, if the device tree happens to cross that 1MB boundary, the end of it remains unmapped and the kernel crashes when it attempts to access it. Given no restriction on the location of that DTB, it could end up with only a few bytes mapped at the end of a section. Solve this issue by mapping two consecutive sections.

* ARM: 7627/1: Predicate preempt logic on PREEMP_COUNT not PREEMPT aloneStephen Boyd2013-01-162-5/+5
| | | | | | | | | | | | | | | | | | | | | Patrik Kluba reports that the preempt count becomes invalid due to the preempt_enable() call being unbalanced with a preempt_disable() call in the vfp assembly routines. This happens because preempt_enable() and preempt_disable() update preempt counts under PREEMPT_COUNT=y but the vfp assembly routines do so under PREEMPT=y. In a configuration where PREEMPT=n and DEBUG_ATOMIC_SLEEP=y, PREEMPT_COUNT=y and so the preempt_enable() call in VFP_bounce() keeps subtracting from the preempt count until it goes negative. Fix this by always using PREEMPT_COUNT to decided when to update preempt counts in the ARM assembly code.

On uniprocessor CPUs, this is defined as zero and therefore no flushing will take place. Rather than invent a new interface for UP systems, instead use our SMP_ON_UP patching code to read the LoUU from the CLIDR instead.

This was harmful in case of the XIP kernel, as being placed in the RAM range, most likely far from the ROM address, was inflating the XIP images. Moving the .notes at the end of the read-only section (consisting of .text, .rodata and unwind info) fixes the problem.
