    [IA64] Drop debug test/printk that some special pages are marked reserved · 43c518d1
    Tony Luck authored
    In commit 92923ca3 "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.
