2011-07-21ARM: Fix build errors caused by adding generic macrosRussell King
Commit 66a625a (ARM: mm: proc-macros: Add generic proc/cache/tlb struct definition macros) introduced build errors when PM_SLEEP is not enabled. The per-CPU do_suspend/do_resume functions are defined via the preprocessor to constant 0. However, the macros which use these were converted to assembly, resulting in undefined references to these functions. Fix that by moving the ! ifdef section into proc-macros.S and deleting it from all effected proc-*.S files.

2011-07-19ARM: 7000/1: LPAE: Use long long printk format for displaying the pudCatalin Marinas
Currently using just long but this is not enough for the LPAE format (64-bit entries). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-07-19ARM: btc: avoid invalidating the branch target cache on kernel TLB maintanenceRussell King
Kernel space needs very little in the way of BTC maintanence as most mappings which are created and destroyed are non-executable, and so could never enter the instruction stream. The case which does warrant BTC maintanence is when a module is loaded. This creates a new executable mapping, but at that point the pages have not been initialized with code and data, so at that point they contain unpredictable information. Invalidating the BTC at this stage serves little useful purpose. Before we execute module code, we call flush_icache_range(), which deals with the BTC maintanence requirements. This ensures that we have a BTC maintanence operation before we execute code via the newly created mapping. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

One less dependency on mach/memory.h. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>
2011-07-18ARM: change ARM_DMA_ZONE_SIZE into a variableNicolas Pitre
Having this value defined at compile time prevents multiple machines with conflicting definitions to coexist. Move it to a variable in preparation for having a per machine value selected at run time. This is relevant only when CONFIG_ZONE_DMA is selected. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

2011-07-12ARM: dma: replace ISA_DMA_THRESHOLD with a variableRussell King
ISA_DMA_THRESHOLD has been unused by non-arch code, so lets now get rid of it from ARM by replacing it with arm_dma_zone_mask. Move dma_supported() and dma_set_mask() out of line, and have dma_supported() check this new variable instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-07-08ARM: 6995/2: mm: remove unnecessary cache flush on v6 copypageHeechul Yun
Originally introduced to maintain coherency between icache and dcache in v6 nonaliasing mode. This is now handled by __sync_icache_dcache since c0177800, therefore unnecessary in this function.

2011-07-08ARM: 6996/1: mm: Poison freed init memoryStephen Boyd
Poisoning __init marked memory can be useful when tracking down obscure memory corruption bugs. Therefore, poison init memory with 0xe7fddef0 to catch bugs earlier. The poison value is an undefined instruction in ARM mode and branch to an undefined instruction in Thumb mode.

2011-07-07ARM: vmlinux.lds: move init sections between text and data sectionsRussell King
Place the init sections between the text and data sections. This means all code is grouped together at the beginning of the kernel image, and all data is at the end of the image. This avoids problems with the 24-bit branch instruction relocations becoming invalid with large initramfs images.

2011-07-07ARM: proc: add definition of cpu_reset for ARMv6 and ARMv7 coresWill Deacon

2011-07-07ARM: proc: add proc info for Cortex-A15MP using classic page tablesWill Deacon
Multicore implementations of the Cortex-A15 require bit 6 of the auxiliary control register to be set in order for cache and TLB maintenance operations to be broadcast between CPUs. This patch adds a new proc_info structure for Cortex-A15, which enables the SMP bit during setup and includes the new HWCAP for integer division. Signed-off-by: Will Deacon <will.deacon@arm.com>

2011-07-07ARM: proc: convert v7 proc infos into a common macroPawel Moll
As most of the proc info content is common across all v7 processors, this patch converts existing A9 and generic v7 descriptions into a macro (allowing extra flags in future). Signed-off-by: Pawel Moll <pawel.moll@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
