This fixes the mighty penguin logo not appearing on visual workstation
framebuffer.  The trouble is missing 'case FB_VISUAL_PSEUDOCOLOR:' in
fb_prepare_logo() function.

This fixes the visws framebuffer driver which needs vm_area_struct from
linux/mm.h

Here is the cleanup patch I promised back in February.  Sorry it took a
while.

The effects should be purely cosmetic in 2.5.66.  However, the new
interface for the proper way to send thread-specific of process-global
signals from inside the kernel is needed for correct implementation of
some fixes to timer stuff that Ulrich told me about.

This cleans up some obsolete comments and macros in kernel/signal.c,
restores send_sig_info to its original behavior, and adds a global entry
point send_group_sig_info.  I checked all the uses of send_sig and
send_sig_info and changed a few to send_group_sig_info.

I think it would be cleanest if the whole mess of *_sig* entry points were
reduced to two or three, but I did the change that minimized the number of
callers I had to fix up.

There should be no discernible difference, since the 2.5.66 send_sig_info
function did group semantics for those signals by number already.  The only
exception to that is pdeath_signal, which I guess can be any signal number
but I deemed ought to be process-wide.

I did not change any of the calls using SIGKILL, though that does have
process-wide semantics.  There is no need to change it since SIGKILL always
kills the whole group, though the code path for send_sig(SIGKILL,...) calls
in multithreaded processes will be different now.

OK, so I screwed up - didn't notice the late_initcall() that was
introduced, which was obviously bogus. This one should build OK for the
module case. I've tested insmod/rmmod alongside a mounted sysfs.

I think the built-in case is OK: oprofile/ is after kernel/ in the link
order. I tested that too.

ACPI is performing a spin_lock() on a `void *'.  That's OK when spin_lock is
implemented via an inline function.  But when it is implemented via macros
it causes compile-time breakage.

So cast it to the right type. It really should be fixed not to use opaque
handles, though.

This fixes some performance problems.  Some vendors implement firmware
updates over IPMI, and this speeds up that process quite a bit.

 * Improve the "send - wait for response - send -wait for response -
   etc" performance when using high-res timers.  Before, an ~10ms delay
   would be added to each message, because it didn't restart the timer
   if nothing was happing when a new message was started.

 * Add some checking for leaked messages.

We really need a memory barrier in smp_call_function(), so that the
other cpu's get the updated value when they get IPI'd immediately
afterwards.

This seems to be true on some old (and arguably broken) hardware where
the IPI generation and reception doesn't synchronize enough.

This patch swaps the arguments of kmalloc, and relax the type
of allocation to GFP_KERNEL as others PnP functions do.

1) Use PTREGS_OFF consistently
2) Define it to allocate STACKFRAME_SZ instead of REGWIN_SZ
3) Kill off REGWIN_SZ, replace with sizeof(struct reg_window).

The current ext3 totally ignores I/O errors that happened during a
journal_force_commit time, causing user space to falsely believe it has
succeeded, which actually did not.

This patch  checks IO error during  journal_commit_transaction. and aborts
the journal when there is I/O error.

Originally I thought about reporting the error without doing aborting the
journal, but it probably needs a new flag. Aborting the journal seems to be
the easy way to  signal "hey sth is wrong..".

ext3 allocates and frees at least one handle structure for each system call.
kmalloc and kfree are apparent in the profiles.

Adding a slab cache for these objects takes the overhead for a write() from
1.63 microseconds down to 1.56.

For an appending write, ext3_commit_write() will call the expensive
ext3_mark_inode_dirty() twice.  Once in generic_commit_write()'s extension of
i_size and once in ext3_commit_write() itself where i_disksize is updated.

But by updating i_disksize _before_ calling generic_commit_write() these can
be piggybacked.

The patch takes the overhead of a write() from 1.96 microseconds down to
1.63.

ext3_mark_inode_dirty() (and several other callers) use the
ext3_reserve_inode_write() and ext3_mark_ioc_dirty() pair for journalling an
inode's backing block.

Because ext3_reserve_inode_write() gets journalling access to the block there
is no need for ext3_mark_iloc_dirty() to do it as well.

This change reduces the overhead of a write() from 2.7 microseconds to 1.95
on a 2.7G P4.

The buffer_uptodate flag gets cleared on IO failure, and this can panic jbd
when it tries to write such a buffer.  Relax the panic to be just a warning.

From: Stephen Tweedie <sct@redhat.com>

Add a new form of assert failure in ext3 which allows us to flag events which
are *usually* bugs, but which can be legally triggered in the presence of IO
failures.  Don't panic the kernel on such errors unless we've defined
#JBD_PARANOID_IOFAIL, which will normally be set only for testing purposes.
