  memblock: use binary search to locate candidate regions (2026-10-15 09:39:37 +0300)

There is a conflict in mm/sparse-vmemmap.c and here is how my resolution shows
up with git diff --cc 17bb0e2f6c804  -- mm/sparse-vmemmap.c:

memblock: updates for 7.4-rc1

Performance improvement:

* Use binary search in memblock_add_range() and memblock_isolate_range()

Cleanups:

* Several simplifications in memblock and mm_init that remvove redundand
  code.
* After rework of sparsemem buffer preallocation, memmap_alloc() does not
  require exact_nid parameter. Remove that parameter, drop now unused
  memblock_alloc_exact_nid_raw() and ajust memblock tests accordingly.

memblock test updates:

* add coverage for lowmem allocations
* fix 32-bit build warinings

----------------------------------------------------------------
