2006-03-17[PATCH] powerpc: Fix bug in bug fix for bug in lmb_alloc()Michael Ellerman
My patch (d7a5b2ffa1352f0310630934a56aecbdfb617b72) to always panic if lmb_alloc() fails is broken because it checks alloc < 0, but should be checking alloc == 0. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-07[PATCH] powerpc: Move LMB_ALLOC_ANYWHERE out of lmb.hMichael Ellerman
LMB_ALLOC_ANYWHERE doesn't need to be part of the API, it's only used in lmb.c - so move it out of the header file. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-07[PATCH] powerpc: Always panic if lmb_alloc() failsMichael Ellerman
Currently most callers of lmb_alloc() don't check if it worked or not, if it ever does weird bad things will probably happen. The few callers who do check just panic or BUG_ON. So make lmb_alloc() panic internally, to catch bugs at the source. The few callers who did check the result no longer need to. The only caller that did anything interesting with the return result was careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic automatically, a little messy, but passable.

2006-02-07[PATCH] powerpc: Make sure we don't create empty lmb regionsMichael Ellerman
To prevent problems later in boot, make sure we don't create zero-size lmb regions. I've checked all the callers, and at the moment no one should ever hit this. All callers use a constant size, or they check the computed size before they call us. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-16[PATCH] powerpc: Fixup debugging in lmb.cMichael Ellerman
Somewhere we lost the include of udbg.h in lmb.c. While we're there, add a DBG macro like every other file has and use it in lmb_dump_all(). Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Merge lmb.c and make MM initialization use it.Paul Mackerras
This also creates merged versions of do_init_bootmem, paging_init and mem_init and moves them to arch/powerpc/mm/mem.c. It gets rid of the mem_pieces stuff. I made memory_limit a parameter to lmb_enforce_memory_limit rather than a global referenced by that function. This will require some small changes to ppc64 if we want to continue building ARCH=ppc64 using the merged lmb.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
