page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash()

2008-08-12T23:07:27+00:00

.. since a failed allocation is being (initially) handled gracefully, and panic()-ed upon failure explicitly in the function if retries with smaller sizes failed. Signed-off-by: Jan Beulich Signed-off-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

bootmem: Move node allocation macros back to !HAVE_ARCH_BOOTMEM_NODE

2008-07-25T18:36:44+00:00

These got unintentionally moved, put them back as x86 provides its own versions. Signed-off-by: Johannes Weiner Signed-off-by: Linus Torvalds

bootmem: replace node_boot_start in struct bootmem_data

2008-07-24T17:47:20+00:00

Almost all users of this field need a PFN instead of a physical address, so replace node_boot_start with node_min_pfn.

bootmem: clean up alloc_bootmem_core

2008-07-24T17:47:20+00:00

alloc_bootmem_core has become quite nasty to read over time. This is a clean rewrite that keeps the semantics. bdata->last_pos has been dropped. bdata->last_success has been renamed to hint_idx and it is now an index relative to the node's range. Since further block searching might start at this index, it is now set to the end of a succeeded allocation rather than its beginning. bdata->last_offset has been renamed to last_end_off to be more clear that it represents the ending address of the last allocation relative to the node.

bootmem: reorder code to match new bootmem structure

2008-07-24T17:47:19+00:00

This only reorders functions so that further patches will be easier to read. No code changed. Signed-off-by: Johannes Weiner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mm: introduce non panic alloc_bootmem

2008-07-24T17:47:17+00:00

Straight forward variant of the existing __alloc_bootmem_node, only subsequent patch when allocating giant hugepages at boot -- don't want to panic if we can't allocate as many as the user asked for.

mm: unexport __alloc_bootmem_core()

2008-07-24T17:47:14+00:00

This function has no external callers, so unexport it. Also fix its naming inconsistency.

mm: move bootmem descriptors definition to a single place

2008-07-24T17:47:14+00:00

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.

x86: clean up reserve_bootmem_generic() and port it to 32-bit

2008-07-08T08:36:17+00:00

1. add reserve_bootmem_generic for 32bit 2. change len to unsigned long 3. make early_res_to_bootmem to use it Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

Add return value to reserve_bootmem_node()

2008-06-21T18:25:10+00:00

This patch changes the function reserve_bootmem_node() from void to int, returning -ENOMEM if the allocation fails. This fixes a build problem on x86 with CONFIG_KEXEC=y and CONFIG_NEED_MULTIPLE_NODES=y Signed-off-by: Bernhard Walle Reported-by: Adrian Bunk Signed-off-by: Linus Torvalds
