[PATCH] bootmem: miscellaneous coding style fixes

2006-09-26T15:48:45+00:00

It fixes various coding style issues, specially when spaces are useless.  For
example '*' go next to the function name.

[PATCH] bootmem: remove useless __init in header file

2006-09-26T15:48:45+00:00

__init in headers is pretty useless because the compiler doesn't check it, and
they get out of sync relatively frequently.  So if you see an __init in a
header file, it's quite unreliable and you need to check the definition
anyway.

[XFRM]: Dynamic xfrm_state hash table sizing.

2006-09-22T22:08:41+00:00

The grow algorithm is simple, we grow if:

1) we see a hash chain collision at insert, and
2) we haven't hit the hash size limit (currently 1*1024*1024 slots), and
3) the number of xfrm_state objects is > the current hash mask

All of this needs some tweaking.

Remove __initdata from "hashdist" so we can use it safely at run time.

[PATCH] FRV: Fix FRV arch compile errors

2006-07-10T20:24:21+00:00

Fix some FRV arch compile errors, including:

 (*) Marking nr_kernel_pages as __meminitdata so that references to it end up
     being properly calculated rather than being assumed to be in the small
     data section (and thus calculated wrt the GP register).  Not doing this
     causes the linker to emit errors as the offset is too big to fit into the
     load instruction.

 (*) Move pm_power_off into an unconditionally compiled .c file as it's now
     unconditionally accessed.

 (*) Declare frv_change_cmode() in a header file rather than in a .c file, and
     declare it asmlinkage.

[PATCH] wait_table and zonelist initializing for memory hotadd: change to meminit for build_zonelist

2006-06-23T14:42:46+00:00

Change definitions of some functions and data from __init to __meminit.

These functions and data can be used after bootup by this patch to be used for
hot-add codes.

[PATCH] x86_64: Handle empty PXMs that only contain hotplug memory

2006-04-09T18:53:16+00:00

The node setup code would try to allocate the node metadata in the node
itself, but that fails if there is no memory in there.

This can happen with memory hotplug when the hotplug area defines an so
far empty node.

Now use bootmem to try to allocate the mem_map in other nodes.

And if it fails don't panic, but just ignore the node.

To make this work I added a new __alloc_bootmem_nopanic function that
does what its name implies.

TBD should try to use nearby nodes here.  Currently we just use any.
It's hard to do it better because bootmem doesn't have proper fallback
lists yet.

[PATCH] for_each_online_pgdat: for_each_bootmem

2006-03-27T16:44:47+00:00

Add a list_head to bootmem_data_t and make bootmems use it.  bootmem list is
sorted by node_boot_start.

Only nodes against which init_bootmem() is called are linked to the list.
(i386 allocates bootmem only from one node(0) not from all online nodes.)

A summary:
 1. for_each_online_pgdat() traverses all *online* nodes.
 2. alloc_bootmem() allocates memory only from initialized-for-bootmem nodes.
