| | | | | | | | | | | | Sanitise the ARM headers exported to userspace. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* | [ARM] Cleanup arch/arm/mm a littleRussell King2006-09-201-3/+0
|/ | | | | | | | | | Move top_pmd into arch/arm/mm/mm.h - nothing outside arch/arm/mm references it. Move the repeated definition of TOP_PTE into mm/mm.h, as well as a few function prototypes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 3815/1: headers_install support for ARMRalph Siemsen2006-09-181-2/+2
| | | | | | | | Move kernel-only #includes into #ifdef __KERNEL__, so that headers_install target can be used on ARM. Signed-off-by: Ralph Siemsen <ralphs@netwinder.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] nommu: adjust headers for !MMU ARM systemsRussell King2006-06-281-0/+8
| | | | | | | | | | | | | | | | | | | | | Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S.

* [ARM] 3377/2: add support for intel xsc3 coreLennert Buytenhek2006-03-281-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek This patch adds support for the new XScale v3 core. This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.

* [ARM] 3101/1: ARM EABI: slab memory must be 64-bit alignedNicolas Pitre2006-01-141-0/+7
| | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre Although ARM is still using 32-bit pointers, version 5 and later versions of the ARM architecture introduced the ldrd and strd instructions to move 64-bit data which must be 64-bit aligned in memory, and the EABI includes new constraints on structure data alignment to allow for the compiler to use those instructions. This means that any slab allocation must start on a 64-bit boundary which is not equivalent to BYTES_PER_WORD, especially on those architecture versions that implements the ldrd/strd instructions. Overriding the default alignment disables some slab debug features. If those debug features are really needed then the kernel will have to be compiled for version 4 of the ARM architecture.

* [PATCH] mm: consolidate get_orderStephen Rothwell2005-09-051-14/+2
| | | | | | | | | | | | Someone mentioned that almost all the architectures used basically the same implementation of get_order. This patch consolidates them into asm-generic/page.h and includes that in the appropriate places. The exceptions are ia64 and ppc which have their own (presumably optimised) versions.

* [PATCH] ARM: Move copy/clear user_page locking into implementationRussell King2005-05-101-13/+2
| | | | | | | | | Move the locking for copy_user_page() and clear_user_page() into the implementations which require locking. For simple memcpy/ memset based implementations, the locking is extra overhead which is not necessary, and prevents preemption occuring. Signed-off-by: Russell King <rmk@arm.linux.org.uk>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
