The patch titled
page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash()
has been removed from the -mm tree. Its filename was
page-allocator-use-no-panic-variant-of-alloc_bootmem-in-alloc_large_system_hash.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: page allocator: use no-panic variant of alloc_bootmem() in alloc_large_system_hash()
From: Jan Beulich <jbeulich@xxxxxxxxxx>
.. since a failed allocation is being (initially) handled gracefully, and
panic()-ed upon failure explicitly in the function if retries with smaller
sizes failed.
