NAKAMURA Gou 2e5874880a procfs: delay ack until get_procfs_entry() ends 
This commit avoids the problem that causes get_procfs_entry() to create
entries which have same name.  See get_procfs_entry().

Masamichi Takagi 8751b32b30 Suppress kernel message when missing remote PTE 
The page-fault handler called on the Linux side looks for a matching PTE
in the page table residing in McKernel. If it fails to find it, it
wrote a confusing kernel message. It's supressed now because it's not an
error.
