mm: introduce dump_vma
Introduce a helper to dump information about a VMA, this also makes
dump_page_flags more generic and re-uses that so the output looks very
similar to dump_page:
[ 61.903437] vma ffff88070f88be00 start 00007fff25970000 end 00007fff25992000
[ 61.903437] next ffff88070facd600 prev ffff88070face400 mm ffff88070fade000
[ 61.903437] prot 8000000000000025 anon_vma ffff88070fa1e200 vm_ops (null)
[ 61.903437] pgoff 7ffffffdd file (null) private_data (null)
[ 61.909129] flags: 0x100173(read|write|mayread|maywrite|mayexec|growsdown|account)
[[email protected]: make dump_vma() require CONFIG_DEBUG_VM]
[[email protected]: fix dump_vma() compilation]
