It appears the loop driver has had one flush_dcache_page() call added for
the case where it writes to the backing device page cache pages.

However, it seems to be missing the call where it writes to its own page
cache pages.

It looks like the call to sched_balance_exec() from do_execve() is in the
wrong spot.  The code calls sched_balance_exec() before determining whether
"filename" actually exists.

In many cases, users have several entries in $PATH.  If a full path name is
not specified on the 'exec" call, the library code iterates thru the files
in the PATH list until it finds the program.  This can result is numerous
migrations of the parent process before the program is actually found.

`make buildcheck' only checks for calls to linker discarded sections,

reference_init checks for calls to sections discarded at run time, init was
cloned from discarded.  They are separate because the linker detects the
discarded case and I did not want to confuse users with messages about init
text/data while they were fixing the linker errors.

The patch examines a putative partition table, and if that doesnt look like a
valid partition table it goes away again.

Some devices have partition tables (and there are many styles of such), some
don't.  Traditionally fixed disks have one, floppies don't.  Nobody knows what
happens with ZIP disks, USB sticks and other such things.  Both the DOS-type
partition table, and the "big floppy" whole disk FAT filesystem are common.
It is undesirable for the kernel to detect partitions where there are none.
This leads to great confusion, sometimes to kernel crashes.

In the particular case of DOS-type partition tables a partition entry has a
1-byte field boot_ind that traditionally is 0x80 for the boot partition and 0
for the other three primary partitions.  Linux does not use this field, and
one sometimes sees tables with all four entries zero.

The patch tells the kernel not to think that something is a valid DOS-type
partition table when a value other than 0 or 0x80 is encountered.  I think it
is a fairly safe change: I do not know of any fdisk-type program that will
write other values there.

On some systems it can take a hotplugged cpu much longer to come up than it
would at boot.  If the cpu comes up after we've given up on it, it tends to
die in its first attempt to kmem_cache_alloc (uninitialized percpu data, I
imagine).

In my experimentation I haven't seen a processor take more than one second
to become available; the patch waits five seconds just to be safe.

DCR number is encoded in mfdcr/mtdcr command itself and this prevents easy
DCR access when register number is not known on compile time.  This patch
adds __mfdcr & __mtdcr helpers which use pre-generated mfdcr/mtdcr
sequences for all possible DCR numbers.  We also use GCC extension
__builtin_constant_p to optimize cases when DCR number is in fact known
during compilation.

- Off-by-one in balance_pgdat means that we're not scanning the zones all
  the way down to priority=0.

- Always set zone->temp_priority in shrink_caches().  I'm not sure why I had
  the `if (zone->free_pages < zone->pages_high)' test in there, but it's
  preventing us from setting ->prev_priority correctly on the
  try_to_free_pages() path.

- Set zone->prev_priority to the current priority if it's currently a
  "lower" priority.  This allows us to build up the pressure on mapped pages
  on the first scanning pass rather than only on successive passes.

Writing to ramfs files with O_SYNC dereferences null in mpage_writepages(),
due to null a_ops->writepage.  The call path is

	generic_file_aio_write_nolock
	->generic_osync_inode
	  ->write_inode_now
	    ->__writeback_single_inode
	      ->__sync_single_inode
	        ->do_writepages
	          ->mpage_writepages

The best fix for this is to visit all ram-backed filesystems and give them a
no-op a_ops.writepages.  But baling out if the file is memory-backed is a
sufficient coverall and is how we handle this in __filemap_fdatawrite().

When taskfile delivery is improved, we will actually perform
this command, instead of no-oping it.

For now, this is cosmetic except for removing an annoying message
that some users see.

The ->tf_load and ->exec_command driver hooks were changed to assume
that PIO was the only type of taskfile ever delivered to these functions.
This will be true... in the future, but not today.  In other drivers
this change was not needed, but Promise executes commands differently
due to its "ATA packet" hardware features, so the Promise drivers need
this change reverted.

- fixed kbuild problems with wanxl firmware (building kernel in separate

This patch is what we want.  We don't in fact need to do the read
lock, only the write lock, which is what the original patch did.
However, we need to do it in ppp_synctty.c as well as ppp_async.c.

Revert CONFIG_NET_GIGE change.

The proper fix is _not_ NET_ETHERNET or default twiddling,
but better overall organization of the ethernet driver selection,
which would include not only CONFIG_NET_GIGE but other options as well.

Reverted back to old behavior until a full and complete solution
appears (and people like it, of course).

I received a bug report that a PLIP interface was incorrectly identified

This patch fixes exactly that.
