x86: Dump filtering supports x86_64 sparsemem
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".

So marking struct pernet_operations is a disaster for modules in two ways.
- We discard it before we call the exit method it points to.
- Because I keep struct pernet_operations on a linked list discarding
it for compiled in code removes elements in the middle of a linked

__setup_str_ide_generic_all becomes const).
Now all __{dev}initdata data in generic IDE PCI host driver are read-only

It turns out that const and __{dev}initdata cannot be mixed currently.
This patch workarounds the problem by removing __devinitdata tag from 'primary'
variable (which makes 'primary' to be moved from .init.data to .bss section).
Now all __devinitdata data in cy82c693 host driver are read-only so it builds
again (driver's .init.data section gets marked as READONLY).
While at it:
* Move 'primary' variable to its only user, init_iops_cy82c693().
1) Patch doesn't change any code here, so gcc is already smart enough
to "feel" constness in such simple functions.
2) There is no such thing as const task_struct. Anyone who think
otherwise deserves compiler warning.
