The patch titled
Subject: ia64: discontig: paging_init(): remove local max_pfn calculation
has been removed from the -mm tree. Its filename was
ia64-discontig-paging_init-remove-local-max_pfn-calculation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: ia64: discontig: paging_init(): remove local max_pfn calculation
The maximal PFN in the system is calculated during find_memory() time and
it is stored at max_low_pfn then.
Use this value in paging_init() and remove the redundant detection of
max_pfn in that function.
