Sometimes, it's useful to have locking.  Especially when we're
talking about time keeping.

It would appear that shemminger's patch of 5th February 2003
completely missed updating _ANY_ ARM timer implementations and,
because linux-arch didn't exist at the time, there appears to
have been no notification to any architecture developer that
maybe, just maybe, some work was required.

One wonders how many other changes are in the kernel which
architecture maintainers have missed.

- Ensure FIQs are enabled when cpu_idle() is called.
- Remove unused members of irq_cpustat_t.
- Remove unnecessary #ifndef CONFIG_SMP...#endif around irq_exit()
  macro.
- Rename __stf/__clf such that it stresses that they affect only
  local state (as per local_irq_xxx).
- Move THREAD_SIZE such that it can be used in current_thread_info()

The orphan list holds inodes that need to be truncated on recovery.  In the
O_DIRECT case, it's used if we extend the inode --- the truncate on recovery
means we'll recover the newly-allocated disk blocks if we crash after the IO
starts but before i_size is updated on disk.

Now, the orphan list is *also* used to delete inodes that are unlinked but
still-open.  Those get truncated but also deleted on recovery.

The orphan list is held both in memory and on disk.  So the rules are that the
inode can't be reclaimed while on the orphan list.  There are only two cases
--- either the inode is actively being written(O_DIRECT) or truncated (in
which case the inode is by definition not going to be reused), or it's
unlinked but still open (again, non-reclaimable).

But in the case where you're truncating or write(O_DIRECT)ing a file that is
*ALSO* unlinked, there's a problem --- the final unlink would put the inode on
the orphan list, but the write/truncate would try to add/remove it.  End
result is that the inode disappears from the orphan list while it's still
unlinked-but-in-use.

That's just a leak-on-crash, it's not going to be detectable in normal use. 
But it's still a bug, and the way we fix it is for direct-IO and truncate not
to do the ext3_orphan_del if the file is unlinked (ie.  i_nlink==0).

The following patches provide an interface to the lease subsystem in the
current VFS locking code.  NFSv4 delegations and Samba op-locks share most
architecture features.  The version 4 NFS server delegation implementation
should use leases to co-ordinate behavior between local, Samba, and NFS
access.


The main design points are

- Seperate the fcntl interface from the file_lock FL_LEASE processing in
  fcntl_setlease, creating __setlease() called by fcntl_setlease()

- Add new lock_manager callbacks to enable lease properties to be set,
  leases to be broken, and leases to be cleaned up: with default callbacks
  preserving the current fcntl_setlease properties.

- Add a new interface, setlease() which also calls __setlease(), and
  remove_lease() for kernel lease managers (e.g.  the v4 NFS server)


This patch:

Add a lock manager copy lock callback to locks_copy_lock() so that nfsd can
set lease properties.

This patch adds efficeon as a cpu option, and makes a small update to the
transmeta cpuid code.  (i wasn't sure if the various doc files are UTF-8...
if they are, then the e should be a U-275 ;)

The compile options may not be ideal, but they're probably close.  i used
-march=pentium3, but -march=pentium4 would have been good enough too.

The cpuid update teaches transmeta.c about the extended processor revision
present in cpuid level 0x80860002...  the external documentation does not
indicate how to break apart this field, and instructs only that the 32-bit
value should be printed in hex (alas).

I've noticed that under specific circumstances the "console=" kernel
parameter is ignored.  This happens when EARLY_PRINTK is enabled and the
serial console is the only available.  In this case unregister_console()
when called for the early console sets preferred_console back to -1
replacing the value that was recorded by console_setup() -- the order of
calls is as follows:

1. register_console() -- for the early console,

2. console_setup() -- recording the console index for the real console,

3. unregister_console() -- for the early console, erasing the console
   index recorded above,

4. register_console() -- for the real console, picking up the first device
   available, instead of the selected one.

I've observed this problem with a DECstation system using ttyS3 -- its
default console device from the firmware's point of view.

The solution is to restore the setting of "console=" upon
unregister_console().  This made a snapshot of 2.4.26 work for me.  I
wasn't able to test the changes with 2.6 because DECstation drivers don't
support it yet, but the code responsible for console selection appears
functionally the same.  So I've concluded it needs the same change.  Here's
a patch.
