v2 cover Remove ARM meminfo
Hi,
This is v2 of the patch to get rid of meminfo. This should cover all the bases. Testing would be appreciated.
Thanks,
Laura

PATCH v2 1/2 mm/memblock: add memblock_get_current_limit
Appart from setting the limit of memblock, it's also useful to be able to get the limit to avoid recalculating it every time. Add the function to do so.

Looks OK to me. Your "[PATCHv2 2/2] arm: Get rid of meminfo" did not make it into my inbox or into my lkml folder, but I found it at lkml.org so the server did send it. I'm not sure what's up with that.
Please include [patch 1/2] within or alongside [patch 2/2] so they both get merged via the same route, which is presumably an arm tree.

PATCH v2 2/2 arm: Get rid of meminfo
In reply to Laura Abbottmemblock is now fully integrated into the kernel and is the prefered method for tracking memory. Rather than reinvent the wheel with meminfo, migrate to using memblock directly instead of meminfo as an intermediate.

So, I also just noticed that you specifically remove the call to sharpsl_save_param() here. I'm presuming that this is also an error, as you haven't removed it from any of the other pxa fixups, and it seems unrelated to the change.

With the changes to this function, I think you can outright remove early_init_dt_add_memory_arch() from arch/arm/kernel/devtree.c. The default implementation (__weak) in drivers/of/fdt.c uses memblock directly.
