simplify procfs code for seq_file instances V3
We currently have hundreds of proc files that implement plain, read-only seq_file based interfaces. This series consolidates them using new procfs helpers that take the seq_operations or simple show callback directly. A git tree is available at: git://git.infradead.org/users/hch/misc.git proc_create.3 Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/proc_create.3 Changes since V2: - use unsigned int for state_size everywhere - move state_size around in proc_dir_entry to use a struct packing hole - update SIZEOF_PDE_INLINE_NAME - added a new proc_pid_ns helper - improved a few changelogs - added back a nubus comment - minor typo fix - collected various ACKs Changes since V1: - open code proc_create_data to avoid setting not fully initialized entries live - use unsigned int for state_size - dropped the s390/cio/blacklist hunk as it has a write method - dropped the IPMI patch given that IPMI proc support is scheduled for removal.
