Subject: xen/debugfs: Add 'p2m' file for printing out the P2M layout.
X-Git-Tag: v2.6.39-rc1~521^2~3
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2222e71bd6eff7b2ad026d4ee663b6327c5a49f5;p=pandora-kernel.git

xen/debugfs: Add 'p2m' file for printing out the P2M layout.

We walk over the whole P2M tree and construct a simplified view of
which PFN regions belong to what level and what type they are.

Only enabled if CONFIG_XEN_DEBUG_FS is set.

[v2: UNKN->UNKNOWN, use uninitialized_var]
[v3: Rebased on top of mmu->p2m code split]
[v4: Fixed the else if]
