[IA64] Drop debug test/printk that some special pages are marked reserved
In commit 92923ca3aace "mm: meminit: only set page reserved in the memblock region" we dropped setting the reserved bits for all pages. This results in some warnings on ia64: put_kernel_page: page at 0xe000000005588000 not in reserved memory put_kernel_page: page at 0xe000000005588000 not in reserved memory put_kernel_page: page at 0xe000000005580000 not in reserved memory put_kernel_page: page at 0xe000000005580000 not in reserved memory put_kernel_page: page at 0xe000000005580000 not in reserved memory put_kernel_page: page at 0xe000000005580000 not in reserved memory the two different pages match up with two objects from the loaded kernel that get mapped by arch/ia64/mm/init.c:setup_gate() a000000101588000 D __start_gate_section a000000101580000 D empty_zero_page In a discussion with Mel Gorman: http://lkml.kernel.org/r/20150526102219.GB13750%40suse.de he suggested that while the preferred approach might be to set the reserved bit for these pages, it would also be OK to just drop the test: "as it's a debugging check that is ia-64 specific" After hunting around a bit and failin to find a good place to mark these pages as reserved - I decided to just delete the test.
