bootmem: Add free_bootmem_late()
Add a new function for freeing bootmem after the bootmem allocator has been released and the unreserved pages given to the page allocator. This allows us to reserve bootmem and then release it if we later discover it was not needed. ( This new API will be used by the swiotlb code to recover a significant amount of RAM (64MB). ) Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Cc: chrisw@sous-sol.org Cc: dwmw2@infradead.org Cc: joerg.roedel@amd.com Cc: muli@il.ibm.com Cc: hannes@cmpxchg.org Cc: tj@kernel.org Cc: akpm@linux-foundation.org Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <1257849980-22640-7-git-send-email-fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
