Commit a491486a started obliterating
dirents directly on the medium, when jffs2_can_mark_obsolete(). Removing
them immediately from the f->dents list, however, screws up handling of
f_pos within a directory -- because the offset is equivalent to the
number of entries through the list we are, and the existence of
deletion dirents served to provide 'placeholders' for unlinked
entries. Now, 'rm -r' doesn't even manage to unlink everything in the
directory.

Revert to keeping 'deletion' dirents in the list, at least in memory
even though we no longer write anything to the medium.

This patch adds the symbol "init_level4_pgt" to the vmcoreinfo data so
that makedumpfile (dump filtering command) supports x86_64 sparsemem 
kernel of linux-2.6.24.

makedumpfile creates a small dumpfile by excluding unnecessary pages for
the analysis. It checks attributes in page structures and distinguishes
necessary pages and unnecessary ones. To check them, makedumpfile gets
the vmcoreinfo data which has the minimum debugging information only for
dump filtering.

For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates
the virtual address of page structure into physical address by subtracting
PAGE_OFFSET from virtual address, but this translation isn't effective for
linux-2.6.24 sparsemem kernel, because its page structures are in virtual
memmap area. makedumpfile should translate their virtual address by 4-levels
paging and it needs the symbol "init_level4_pgt".

The kernel only ever supports 1 version of the boot protocol
so there is no need to check the boot protocol revision to
see if a feature is supported.

Both x86 and x86_64 support the same boot protocol so we need
to implement the KEEP_SEGMENTS on x86_64 as well.  It isn't
just paravirt bootloaders that could use this functionality.

Secondly, the actual definition has this as a SHARED_ALIGNED, so the
