2015-09-05sh: use PFN_DOWN macroAlexander Kuleshov1-2/+2
Replace ((x) >> PAGE_SHIFT) with the predefined PFN_DOWN macro. Signed-off-by: Alexander Kuleshov <kuleshovmail@gmail.com> Acked-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-12-11sh: off by one BUG_ON() in setup_bootmem_node()Dan Carpenter1-1/+1
This off by one bug is harmless but it upsets the static checkers and the code is obvious so it doesn't hurt to fix it. The Smatch warning is: arch/sh/mm/numa.c:47 setup_bootmem_node() error: buffer overflow 'node_data' 1024 <= 1024 Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Cc: Paul Mundt <lethal@linux-sh.org> Acked-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-05-18sh: Fix up the NUMA build for recent LMB changes.Paul Mundt1-38/+0
Now that the node 0 initialization code has been overhauled, kill off the now obsolete setup_memory() bits. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-03sh: establish PMB mappings for NUMA nodes.Paul Mundt1-0/+3
In the case of NUMA emulation when in range PPNs are being used for secondary nodes, we need to make sure that the PMB has a mapping for it before setting up the pgdat. This prevents the MMU from resetting. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-12-09sh: NUMA lmb fixesMagnus Damm1-2/+11
This patch updates the NUMA version of setup_memory() with UMA code changes and also modifies the last argument to lmb_alloc_base() to use an address instead of pfn. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-12-09sh: fix size calculation for NUMA node 0Magnus Damm1-1/+1
Fix the NUMA size calculation for node 0. Do the same as the UMA version of setup_memory() and use address instead of pfn when calculating the size. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-11-04sh: Make sure indexes are positiveRoel Kluin1-1/+1
The indexes are signed, make sure they are not negative when we read array elements. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-04sh: Use bootmem ontop of lmb for NUMAMatt Fleming1-13/+23
Like the UP case, use lmb as the foundation of memory resource management on NUMA. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-07-24mm: move bootmem descriptors definition to a single placeJohannes Weiner1-3/+2
There are a lot of places that define either a single bootmem descriptor or an array of them. Use only one central array with MAX_NUMNODES items instead.

2008-05-08sh: add memory resources to /proc/iomemMagnus Damm1-1/+1
Add physical memory resources such as System RAM, Kernel code/data/bss and reserved crash dump area to /proc/iomem. Same strategy as on x86. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle1-2/+2
This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

2007-06-08sh: Support for multiple nodes.Paul Mundt1-0/+92
This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
