2007-01-24[ARM] Fix show_mem() for discontigmemRussell King
show_mem() was assuming incorrectly that the mem_map for any node started at PFN 0. This is obviously wrong; fix it to take account of node_start_pfn. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-07[ARM] 3927/1: Allow show_mem() to work with holes in memory map.Ray Lehtiniemi
show_mem() was not correctly handling holes in the memory map. It was treating the freed sections of the map as though they contained valid struct page entries. This could cause incorrect debugging output or even a kernel panic. This patch keeps the struct meminfo around after system initialization so that show_mem() can use it when scanning memory. show_mem() now walks over each bank of each online node, rather than assuming that each node contains a single contiguous bank.

2006-09-27[ARM] Split ARM MM initialisation for !mmuRussell King
Move the MMU specific code from init.c into mmu.c, and add nommu fixups to nommu.c Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] Separate page table manipulation code from bootmem initialisationRussell King
nommu does not require the page table manipulation code in the bootmem initialisation paths. Move this into separate inline functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] 3859/1: Fix devicemaps_init() XIP_KERNEL odd 1MiB XIP_PHYS_ADDR ↵George G. Davis
translation error The ARM XIP_KERNEL map created in devicemaps_init() is wrong. The map.pfn is rounded down to an even 1MiB section boundary which results in va/pa translations errors when XIP_PHYS_ADDR starts on an odd 1MiB boundary and this causes the kernel to hang. This patch fixes ARM XIP_KERNEL translation errors for the odd 1MiB XIP_PHYS_ADDR boundary case. Signed-off-by: George G. Davis <gdavis@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-20[ARM] Cleanup arch/arm/mm a littleRussell King
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>

2006-06-28[ARM] Remove TABLE_SIZE, and several unused function prototypesRussell King
TABLE_SIZE is never used in arch/arm/mm/init.c. create_memmap_holes(), memtable_init, and setup_io_desc() no longer exist in the kernel. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-04-07[ARM] Move FLUSH_BASE macros to asm/arch/memory.hRussell King
FLUSH_BASE must be visible to arch/arm/mm/init.c in order for the memory region to be setup. Move these definitions from asm-arm/arch-*/hardware.h into asm-arm/arch-*/memory.h where mm stuff can see them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-03-22[PATCH] remove set_page_count() outside mm/Nick Piggin
set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count.

2006-03-21[ARM] Remove unnecessary asm/hardware.h includesRussell King
asm/hardware.h is not required for the majority of processor support files, ioremap support, mm initialisation, acorn IO support, nor the debug code (which picks up its machine specific includes via debug-macros.S) Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-11-17[ARM] Fix some corner cases in new mm initialisationRussell King
Document that the VMALLOC_END address must be aligned to 2MB since it must align with a PGD boundary. Allocate the vectors page early so that the flush_cache_all() later will cause any dirty cache lines in the direct mapping will be safely written back. Move the flush_cache_all() to the second local_flush_cache_tlb() and remove the now redundant first local_flush_cache_tlb(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-11-02[ARM] Fix mm initialisation with write buffered write allocate cachesRussell King
It seems that without the extra tlb flush, we may end up faulting during the early kernel initialisation because the TLB can't see the updated page tables. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-10-28[ARM] Re-jig bootmem initialisationRussell King
Make ARM independent of the way bootmem operates internally. We now map each node as we initialise it, and place the bootmem bitmap inside each node, rather than all in the first node. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

It doesn't make sense for this to be in mm-armv.c now that 26-bit ARM support is no longer integrated into arch/arm. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-22[PATCH] ARM: Remove explicit page-alignments in memory initRussell King
Since meminfo.bank[] array contains page-aligned start/size, we no longer need to explicitly round up/down the addresses when converting to PFNs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-04-16[PATCH] arm: add comment about max_low_pfn/max_pfnakpm@osdl.org
) From: Russell King <rmk+lkml@arm.linux.org.uk> Oddly, max_low_pfn/max_pfn end up being the number of pages in the system, rather than the maximum PFN on ARM.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
