Add discovery for PA-RISC 16550 serial ports.

Patch from Matthew Wilcox.

- Remove last usage of EVT_WRITE_WAKEUP
- Remove unused label + kfree()
- scratch3 now known as id3

The original port detection code was one large function with many
tests without any clear structure.

This cset cleans this up, splitting out the tests for 8250/16450
vs 16550 vs 16550A vs later ports, and adds comments about why
we test what we're testing.

In addition to the Alpha OUT1/OUT2 kludge, devices like Bluetooth
modems connected to serial ports make use of the modem control lines
in non-standard ways.  Therefore, we implement a more flexible way to
allow the modem control outputs to be forced to particular values
irrespective of the normal usage of these signals.

The tty layer's tty_name requires formatting codes in driver->name
for the devfs and non-devfs cases.

- Unlink port from chain if request_irq fails
- Allow port to define whether we use shared IRQs
  (this is required for PCMCIA serial cards where the serial
   card shares the same IRQ as the socket status IRQ.)
- Convert remaining ASYNC_ flags to UPF_ flags

Traditionally, we allocated the private array of port parameters based on
the detected board->num_ports, and then called the init_fn with the board
pointer (which points into the global table.)  Some init_fn implementations
modify num_ports, which therefore affects the global table.  Unfortunately,
this means that if the init_fn increases num_ports (because we have two
almost identical cards, the first with a smaller number of ports than the
second), we will overwrite memory which hasn't been allocated to us.

This cset no longer passes the board pointer into the init_fn, but instead
allows the init_fn to return the number of ports found, or zero to use the
default value in board->num_ports, or negative error number.

uart_event() only has one purpose, which is to wake up any pending
writers via the line discipline.  Rename it to reflect its real
functionality, and drop EVT_WRITE_WAKEUP.

Here's the ext3 version.

I finally had time to look at the Orlov patches, and found a memory
leak; sbi->s_debts wasn't getting freed when the filesystem was
getting unmounted, or in the error path.

This patch also makes the following cleanups/changes:

1) Use sbi->s_debts instead of sbi->debts --- all other fields in
	struct ext2_sb_info are prefixed by "s_", so this makes things
	consistent.

2) Add support for a new inode flag, EXT2_TOPDIR_FL, which tells tells
	the Orlov allocator to treat that directory as the top of
	directory hierarchies, so that new subdirectories created in
	that directory should be spread apart.  System administrators
	should set this flag on directories like /usr/src, /usr/home, etc.

3) Add a mount-time flag, -o oldalloc, which forces the use of the old
	inode (pre-Orlov) allocator.  This makes it easier to do
	comparison benchmarks, and in case people want to use the old
	algorithm.

empty for a while now, and nothing uses it.

don't have to try to figure it out for themselves.

Make ide-cd.c use it.

- Convert to new configuration language and fix up HEX config symbols
- Fix build errors for !CONFIG_KALLSYMS case
- Add module list to oopsen.
- Add POLLREMOVE

For many moons, we've been executing identify_cpu()
on the boot processor twice on SMP kernels.
This is harmless, but has a few downsides..
- Extra cruft in bootlog/dmesg
- Spawns one too many timers for the mcheck handler
- possibly other wasteful things..

This seems to do the right thing here, and has been
acked (after some minor squibbles) on l-k.

Without the below patch, my HT 2-way prints out
"CPUS Done 4294967295" on boot, which whilst amusing
is somewhat exaggerated.

The machine check initialisation prints some blurb
which makes the capabilities dumping a little untidy.
By initialising it slightly later, we get something that
looks a lot better.

  We've uncovered yet another kmap imbalance in the new RPC code.  This
looks like it might be the last one (my debugging printks have been
unable to unearth any more).  One line fix + 4 line comment appended.

a compile failure.

This is a minor cleanup that removes two instances of CONFIG_X86_TSC
(lets the compiler optimize it out), and adds a warning message should
anyone pass "notsc" to a kernel compiled w/ CONFIG_X86_TSC (which
ignores it).

This is basically a forward port of a patch I got into 2.4 a while back.

I like Alan's idea: IGNLABEL("HmacRxAccepted")

From Matthew Dobson.

This final patch from Matthew cleans up a few leftovers which were noted
after the code had been reviewed and tested a bit in the -mm patchsets.

1) Update register_XXX and arch_register_XXX functions to return int
   instead of void.  Functions calling these functions should know if
   they completed successfully to take appropriate further registration
   action, or not bother.

2) Drop some pointless error checking in the arch_register_XXX
   functions.

From Matthew Dobson.

Create and use node_online_map.

This patch creates a node_online_map, much like cpu_online_map.  It
also creates the standard helper functions, ie: node_online(),
num_online_nodes(), node_set_online(), node_set_offline().

This is used by driverFS topology to keep track of which Nodes
are in the system and online.

From Matthew Dobson.

Create and use memblk_online_map.

This patch creates a memblk_online_map, much like cpu_online_map.  It
also creates the standard helper functions, ie: memblk_online(),
num_online_memblks(), memblk_set_online(), memblk_set_offline().

This is used by driverFS topology to keep track of which memory blocks
are in the system and online.
