Mounting a non-affs filesystem as affs crashes the kernel.
The reason is the
	sbi = kmalloc(sizeof(struct affs_sb_info), GFP_KERNEL);
	memset(sbi, 0, sizeof(*AFFS_SB));
where the second sizeof is 1, so that sbi is not zeroed at all.

Also, avoid a warning for printk of sector_t in amigaffs.h.

Previously, we only honored barriers wrt merging. Really honor them now,
move all pending requests to dispatch list and add the hard barrier at
the back.

gen-asm-offsets, the most common user of the new filechk function, needs
to be fed input from $< (the first prerequisite).

Patch from Adrian Bunk <bunk@fs.tum.de>

It would be nice if everyone would try to compile the patched files
before submitting patches...

raid0 doesn't have a thread, so md_wakeup_thread() derefs NULL.

Neil may end up doing this differently, but meanwhile....

Patch from Roman Zippel <zippel@linux-m68k.org>

- remove lock_kernel() (It was buggy too - there are at present two missing
  unlock_kernel()s)

- fixes a bitmap corruption problem.

From latest -aa kernels.

Patch from: Suparna Bhattacharya <suparna@in.ibm.com>

Just an obvious fix.
The kiocbClearX macros were doing a set_bit !
They should be calling clear_bit.
Ran into this now that I'm actually using kiocbClearKicked.

Patch from Alex Tomas <bzzz@tmi.comex.ru>

There is a logic error in ext2_new_block().  If we manage to reserve some
blocks in the final blockgroup, local variable `bit' will be equal to
sbi->s_groups_count and we erroneously assume that the allocation failed.

Fix that up by testing local variable `group_alloc' instead.

Patch from "Theodore Ts'o" <tytso@mit.edu>

I recently noticed a bug in ext2/3; newly created inodes which inherit
the noatime flag from their containing directory do not respect noatime
until the inode is flushed from the inode cache and then re-read later.
This is because the code which checks the ext2 no-atime attribute and
then sets the S_NOATIME in inode->i_flags is present in
ext2_read_inode(), but not in ext2_new_inode().

I fixed this in 2.4, and then found an even worse bug in the 2.5 code;
the DIRSYNC flag is completely ignored *except* in the case where a
directory is newly created using mkdir and its parent directory has the
DIRSYNC flag.  S_DIRSYNC doesn't get set in the ext2_new_inode() or the
ext2_ioctl() paths (which is used by chattr).

This patch centralizes the code which translates the ext2 flags in the
raw ext2 inode to the appropriate flag values in inode->i_flags in a
single location.  This fixes the bug, makes things cleaner, and also
removes 30 lines of code and 128 bytes of compiled x86 text in the
bargain.

Patch from Oleg Drokin <green@linuxhacker.ru>

    There is a memleak in e100 driver from intel, both in 2.4 and 2.5
    e100_ethtool_gstrings does not free "strings" variable if it cannot
    copy it to userspace.

Patch from Anders Gustafsson <andersg@0x63.nu>

We're getting a division-by-zero in the writeback code during early rootfs
population, because writeback has not yet been initialised.

Fix that by performing an explicit initialisation rather than relying on
initcall ordering.

Patch from Kevin Pedretti <pedretti@ieee.org>

The previous fix for unmapping hugetlb regions could still produce incorrect
alignments if the munmap request covers multiple VMA's.

Fix it by always unmapped the entire hugepage VMA inside the inner loop.

Patch from "Randy.Dunlap" <rddunlap@osdl.org>

Reverts the recent alteration of the format of the `mem=' option.  This is
because `mem=' is interpreted by bootloaders and may not be freely changed.

Instead, the new functionality to set specific memory region usages is
provided via the new "memmap=" option.

The documentation for memmap= is added, and the documentation for mem= is
updated.

The recent (untested?) "cleanup" removed a null-pointer test.

As requested by Andrew, this moves the hugetlbfs config option
into the Pseudo filesystems section near tmpfs.

Also fix some spelling.

Patch from Ivan Kokshaysky

This fixes long standing typo ('size' instead of 'r_size') which causes
overestimate of the bridge memory ranges calculated in pbus_size_mem().
For example, if we have a device with one 1Mb and one 2Mb memory ranges
behind the bridge, calculated size and alignment of the bridge memory
window will be 4Mb and 2Mb respectively, while the correct values are
3Mb and 1Mb.

In an attempt to "unuse" pci_do_scan_bus() so it can be eventually
killed, make pci_scan_bus_parented() call the new pci_scan_child_bus()
and pci_bus_add_devices().  The only remaining callers are the
hotplug drivers.

Eventually, pci_bus_add_devices() will be removed from this function -
it is intended that architectures should call this after they have
done any setups and fixups to the scanned bus.

It is legal to call pci_bus_add_devices() on a bus which has already
had this function called, so architectures could update today.

Pull out the bits of cardbus configuration - the secondary latency
timer, and the number of bus numbers we reserve.

pci_read_config_dword() takes a u32 pointer, not unsigned long.

Miscellaneous cleanups to probe.c:
        - make code/comments wrap before column 80.
        - remove extraneous space.

Kill pcibios_update_resource(), replacing it with pci_update_resource().
pci_update_resource() uses pcibios_resource_to_bus() to convert a
resource to a device BAR - the transformation should be exactly the
same as the transformation used for the PCI bridges.

pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
set the high 32-bits to anything non-zero - currently no architecture
attempts to do something different.  If anyone cares, please fix; I'm
going to reflect current behaviour for the time being.

Ivan pointed out the following architectures need to examine their
pcibios_update_resource() implementation - they should make sure that
this new implementation does the right thing.  #warning's have been
added where appropriate.

	ia64
	mips
	mips64

This cset also includes a fix for the problem reported by AKPM where
64-bit arch compilers complain about the resource mask being placed
in a u32.

Convert pcibios_fixup_pbus_ranges() into something more generic, namely
pcibios_resource_to_bus() - we are really trying to convert resources
to something to program into bus registers for bridge windows, and in
fact, PCI device BARs.

This is necessary since some architectures, namely Alpha, ARM and PARISC
have an offset between PCI addressing and host-based addressing, so
resources need to be adjusted when read or when written back to the bus.

We provide a generic version in asm-generic/pci.h, which most
architectures use.

This patch finds the following architectures with something to think
consider:

        - ppc, ppc64
                adjusts resources for devices, but not buses.
		This is inconsistent, and leads to improperly
		programmed windows/BARs.

PPC people (Anton) has a replacement PCI resource implementation
which should do the right thing.

Patch from Ivan Kokshaysky

remove the "parent" or "root" second argument to
pcibios_update_resource().  This highlights the following
architectures doing something wrong in their implementation:

        - ia64
        - mips it8172
        - mips "generic mips boards"
        - mips64 "generic mips boards"
        - mips64 IP27

Fix breakage in pci-3 - we scanned all functions if function 0 was not
present.  This causes some host bridges to lock up when scanning devfn
255 on PPC machines.

This removes/fixes a few whitespaces and removes the MAX_PRIO setting in
the init task path which is unnecessary and which might even lead to
bugs - MAX_PRIO is outside the valid range and technically the init
thread is not an idle thread yet at this point.

This fixes a fundamental (and long-standing) bug in the sleep-average
estimator which is the root cause of the "contest process_load" problems
reported by Mike Galbraith and Andrew Morton, and which problem is
addressed by Mike's patch.

The bug is the following: the sleep_time code in activate_task()
over-estimates the true sleep time by 0.5 jiffies on average (0.5 msecs
on recent 2.5 kernels).  Furthermore, for highly context-switch
intensive and CPU-intensive workloads it means a constant 1 jiffy
over-estimation.  This turns the balance of giving and removing ticks
and nils the effect of the CPU busy-tick, catapulting the task(s) to
highly interactive status - while in reality they are constantly burning
CPU time.

The fix is to round down sleep_time, not to round it up.  This slightly
under-estimates the sleep time, but this is not a real problem, any task
with a sleep time in the 1 jiffy range will see timekeeping granularity
artifacts from various parts of the kernel anyway.  We could use rdtsc
to estimate the sleep time, but i think that's unnecessary overhead.

The fixups in Mike's scheduler patch (which is in -mm8) basically work
around this bug.  The patch below definitely fixes the contest-load
starvation bug, but it remains to be seen what other effects it has on
interactivity.  In any case, this bug in the estimator is real and if
there's any other interactivity problem around then we need to deal with
it ontop of this patch.

This bug has been in the O(1) scheduler from day 1 on basically, so i'm
quite hopeful that a number of interactivity complaints are fixed by
this patch.

Changelog since version 1.68 mark II:
  - merge Mike Anderson's probe() cleanup
     - num_devs is now "per host"
     - num_devs is sysfs writeable
  - add slave_alloc skeleton code

So to simulate 154 disks (for example) one might use:
  # modprobe scsi_debug add_host=11 num_devs=14

With max_luns at its default value of 2, 14 is the
maximum number of devices per host scsi_debug will
respond to (i.e. 7 targets, each with 2 lus).

make's line continuation without explicit backslashes is a mystery
to me, and in this case, vmlinux got linked, but the linker command
was not written to the screen. Works again now.
