Use remove_proc_subtree to remove the whole subtree on cleanup, and
unwind the registration loop into individual calls. Switch to use

Also don't bother handling proc_create* failures - the driver works
perfectly fine without the proc files, and the cleanup will h

Variant of proc_create_data that directly take a seq_file show
callback and deals with network namespaces in ->open and ->release.
All callers of proc_create + single_open_net converted over, and
single_{open,release}_net are removed entirely.

On the 8xx, the GUARDED attribute of the pages is managed in the
L1 entry, therefore to avoid having to copy it into L1 entry
at each TLB miss, we set it in the PMD.

The purpose of this serie is to implement hardware assistance for TLB table walk

First part is to make L1 entries and L2 entries independant.
For that, we need to alter ioremap functions in order to handle GUARD attribute

Last part is to reuse PTE fragment implem

In order to simplify time critical exceptions handling 8xx

For 1GB huge pages allocation, a regression bug is reported when KASLR

Then boot the guest and check number of 1GB pages reserved:

In 16k page size mode, the 8xx need only 4k for a page table.
