This will be used by the array resize code and might prove useful to some arch code as well at which point it can be made non-static. Also add comment as to why aligning size is important Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> --- v2. Fix loss of size alignment v3. Fix result code

This function will be used to locate a free area to put the new memblock arrays when attempting to resize them. memblock_alloc_region() is gone, the two callsites now call memblock_add_region().

Since we allocate one more than needed, why not do a bit of sanity checking here to ensure we don't walk past the end of the array ? Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This is in preparation for having resizable arrays. Note that we still allocate one more than needed, this is unchanged from the previous implementation. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Right now, both the "memory" and "reserved" memblock_type structures have a "size" member. It represents the calculated memory size in the former case and is unused in the latter. This moves it out to the main memblock structure instead Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The RMA (RMO is a misnomer) is a concept specific to ppc64 (in fact server ppc64 though I hijack it on embedded ppc64 for similar purposes) and represents the area of memory that can be accessed in real mode (aka with MMU off), or on embedded, from the exception vectors (which is bolted in the TLB) which pretty much boils down to the same thing. We take that out of the generic MEMBLOCK data structure and move it into arch/powerpc where it belongs, renaming it to "RMA" while at it.

This introduce memblock.current_limit which is used to limit allocations from memblock_alloc() or memblock_alloc_base(..., MEMBLOCK_ALLOC_ACCESSIBLE). The old MEMBLOCK_ALLOC_ANYWHERE changes value from 0 to ~(u64)0 and can still be used with memblock_alloc_base() to allocate really anywhere. It is -no-longer- cropped to MEMBLOCK_REAL_LIMIT which disappears. Note to archs: I'm leaving the default limit to MEMBLOCK_ALLOC_ANYWHERE. I strongly recommend that you ensure that you set an appropriate limit during boot in order to guarantee that an memblock_alloc() at any time results in something that is accessible with a simple __va(). The reason is that a subsequent patch will introduce the ability for the array to resize itself by reallocating itself. The MEMBLOCK core will honor the current limit when performing those allocations. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The implementation is pretty much similar. There is a -small- added overhead by having another function call and the address shift. If that becomes a concern, I suppose we could actually have memblock itself expose a memblock_pfn_valid() which then ARM can use directly with an appropriate #define...

All callers expect a boolean result which is true if the region overlaps a reserved region. However, the implementation actually returns -1 if there is no overlap, and a region index (0 based) if there is. Make it behave as callers (and common sense) expect.
