2008-08-13x86: propagate new nonpanic bootmem macros to CONFIG_HAVE_ARCH_BOOTMEM_NODEJohannes Weiner
Commit 74768ed833344b "page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash()" introduced two new _nopanic macros which are undefined for CONFIG_HAVE_ARCH_BOOTMEM_NODE.

2008-06-10x86: make generic arch support NUMAQYinghai Lu
... so it could fall back to normal numa and we'd reduce the impact of the NUMAQ subarch. NUMAQ depends on GENERICARCH also decouple genericarch numa from acpi. also make it fall back to bigsmp if apicid > 8.

2008-06-03x86, numa, 32-bit: increase max_elements to 1024Yinghai Lu
so every element will represent 64M instead of 256M. AMD opteron could have HW memory hole remapping, so could have [0, 8g + 64M) on node0. Reduce element size to 64M to keep that on node 0 Later we need to use find_e820_area() to allocate memory_node_map like on 64-bit. But need to move memory_present out of populate_mem_map...

2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle
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().
