This changes the hash insertion routines to return an error instead of
calling panic() when HV refuses to insert a HPTE (the hypervisor call to
set up a hashtable PTE is H_ENTER). 

The error is now propagated upstream, and either bad_page_fault() is
called (kernel mode) or a SIGBUS signal is forced (user mode).  Some
other panic() cases are also turned into BUG_ON.

Overall, this should provide us with better debugging data if the
problem happens, and avoids errors from userland mapping /dev/mem and
trying to use forbidden IOs (XFree ?) to bring the whole kernel down.

In contrast to the old "request_resource()", this allows

This patch allows to update the interrupt status register after an Rx
overflow or a Rx fifo error even when the Rx buffer contains no packet.
The update must be kept in the packet processing loop to prevent an Rx
error storm.  As an interesting behavior, the status of the interrupt
status register must not be read early.

sk98line tries to register a procfile with the interfacename of the struct

unless you change the interface name manually, but as Linux explicitly

If tty_open() fails for a normal serial device, we end up doing cleanups
that should only happen for failed open of /dev/ptmx.  The results are
not pretty - devpts et.al.  end up very confused.  That's what gave
problems with ptmx.

This splits ptmx file_operations from the normal case and cleans up both
tty_open() and (new) ptmx_open().  Survived serious beating.

The patch below fixes an interesting oddity we're seeing with fedora core
development (where we recently started using udev heavily); basically right
now filelock_init() is a module_init(), eg runs late.  However that breaks
down because there are earlier /sbin/hotplug callouts, which with udev, do
locking operations.  When that happens the kernel oopses because the slabs
for file locks aren't initialized yet.

Solution: initialize this way early.  It's only a kmem_cache_create after
all, so can happen early.

ncfpfs seems to update inode times by hand everywhere instead of using
the proper helpers.  This means:

 - the atime updates in mmap() and read() seems to miss various checks
   upodate_atime or one of the wrappers does.  Also it doesn't mark the
   inode dirty.
 - in write() you update mtime and _a_time instead of ctime as expected,
   also the usual checks and optimizations are missing.

In addition the fops contain some bogus checks like for a refular file (but
the fops are only used of ISREG files) and inode->i_sb although that is
guranteed to be non-zero.
