[JFFS2] Use MTD_OOB_AUTO to automatically place cleanmarker on NAND

Nowadays MTD supports an MTD_OOB_AUTO option which allows users
to access free bytes in NAND's OOB as a contiguous buffer, although
it may be highly discontinuous.

This patch teaches JFFS2 to use this nice feature instead of the
old MTD_OOB_PLACE option. This for example caused problems with
OneNAND. Now JFFS2 does not care how are the free bytes situated.

This may change position of the clean marker on some flashes,
but this is not a problem. JFFS2 will just re-erase the empty
eraseblocks and write the new (correct) clean marker.

[PATCH] kexec: Avoid migration of already disabled irqs (ia64)

This patch fixes up ia64 kexec support for HP rx2620 hardware.  It does
this by skipping migration of already disabled irqs.  This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.

The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch.  This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs.  So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().

The code has been tested on three different ia64 machines, all with good
results.  It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

flush_workqueue() is not allowed to be called in the softirq context.
However, aio_complete() called from I/O interrupt can potentially call
put_ioctx with last ref count on ioctx and triggers bug.  It is simply
incorrect to perform ioctx freeing from aio_complete.

The bug is trigger-able from a race between io_destroy() and aio_complete().
A possible scenario:

cpu0                               cpu1
io_destroy                         aio_complete
  wait_for_all_aios {                __aio_put_req
     ...                                 ctx->reqs_active--;
     if (!ctx->reqs_active)
        return;
  }
  ...
  put_ioctx(ioctx)

                                     put_ioctx(ctx);
                                        __put_ioctx
                                          bam! Bug trigger!

The real problem is that the condition check of ctx->reqs_active in
wait_for_all_aios() is incorrect that access to reqs_active is not
being properly protected by spin lock.

This patch adds that protective spin lock, and at the same time removes
all duplicate ref counting for each kiocb as reqs_active is already used
as a ref count for each active ioctx.  This also ensures that buggy call
to flush_workqueue() in softirq context is eliminated.

[SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crash

sd_probe() calls class_device_add() even before initializing the
sdkp->device variable. class_device_add() eventually results in the user mode
udev program to be called. udev program can read the the allow_restart
attribute of the newly created scsi device. This is resulting in a crash as
the show function for allow_restart (i.e sd_show_allow_restart) returns the
attribute value by reading the sdkp->device->allow_restart variable. As the
sdkp->device is not initialized before calling the user mode hotplug helper,
this results in a crash.
The patch below solves it by calling class_device_add() only after the
necessary fields in the scsi_disk structure are initialized properly.

the total data transfer length of a command. Make sure
nbytes gets initialized for internally generated commands.

ahci/pata_jmicron: fix JMicron quirk

For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set.  This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.

The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits.  If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.

This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.

Revert "[PATCH] fix typo in geode_configre()@cyrix.c"

This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba.

It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit).  And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.

The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so).  So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.

There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.

[PATCH] __crc_... is intended to be absolute

i386 boot/compressed/relocs checks for absolute symbols and warns about
unexpected ones.  If you build with modversions, you get ~2500 warnings
about __crc_<symbol>.  These suckers are really absolute symbols - we
do _not_ want to modify them on relocation.

They are generated by genksyms - EXPORT_... generates a weak alias, then
genksyms produces an ld script with __crc_<symbol> = <checksum> and it's
fed to ld to produce the final object file.  Their only use is to match
kernel and module at modprobe time; they _must_ be absolute.

boot/compressed/relocs has a whitelist of known absolute symbols, but
it doesn't know about __crc_... stuff.  As the result, we get shitloads
of false positives on any ld(1) version.

kernel (commit 1597cacbe39802d86656d1f2e6329895bd2ef531).

My understanding is that pci_find_present() doesn't work yet at the time
the quirks are run.  So I used a two-step quirk as is done for some other
quirks already.  First we detect the VIA south bridges and set the right
low and high device limits, then we are ready to actually run the quirks on
the affected devices.

[PATCH] kprobes: replace magic numbers with enum

Replace the magic numbers with an enum, and gets rid of a warning on the
specific architectures (ex.  powerpc) on which the compiler considers
'char' as 'unsigned char'.

[PATCH] Remove warning: VFS is out of sync with lock manager

But keep it as a dprintk

The message can be generated in a quite normal situation:
 If a 'lock' request is interrupted, then the lock client needs to
  record that the server has the lock, incase it does.
 When we come the unlock, the server might say it doesn't, even
  though we think it does (or might) and this generates the message.

[PATCH] translate dashes in filenames for headers install

The current filename->define translation does not scrub dashes so when
creating stub defines for like asm-x86_64/ptrace-abi.h, we get: #define

[PATCH] Don't allow the stack to grow into hugetlb reserved regions

When expanding the stack, we don't currently check if the VMA will cross
into an area of the address space that is reserved for hugetlb pages.
Subsequent faults on the expanded portion of such a VMA will confuse the
low-level MMU code, resulting in an OOPS.  Check for this.

[SCTP]: Force update of the rto when processing HB-ACK

When processing a HEARTBEAT-ACK it's possible that the transport rto
timers will not be updated because a prior T3-RTX processing would
have cleared the rto_pending flag on the transport.  However, if
we received a valid HEARTBEAT-ACK, we want to force update the
rto variables, so re-set the rto_pending flag before calling
sctp_transport_update_rto().

[IPV6]: fix BUG of ndisc_send_redirect()

  When I tested IPv6 redirect function about kernel 2.6.19.1, and found
that the kernel can send redirect packets whose target address is global
address, and the target is not the actual endpoint of communication.

  But the criteria conform to RFC2461, the target address defines as
following:

  Target Address An IP address that is a better first hop to use for
                 he ICMP Destination Address.  When the target is
                 the actual endpoint of communication, i.e., the
                 destination is a neighbor, the Target Address field
                 MUST contain the same value as the ICMP Destination
                 Address field.  Otherwise the target is a better
                 first-hop router and the Target Address MUST be the
                 router's link-local address so that hosts can
                 uniquely identify routers.

According to this definition, when a router redirect to a host, the
target address either the better first-hop router's link-local address
or the same as the ICMP destination address field. But the function of
ndisc_send_redirect() in net/ipv6/ndisc.c, does not check the target
address correctly.

There is another definition about receive Redirect message in RFC2461:

8.1.  Validation of Redirect Messages

   A host MUST silently discard any received Redirect message that does
   not satisfy all of the following validity checks:
   ......
   - The ICMP Target Address is either a link-local address (when
     redirected to a router) or the same as the ICMP Destination
     Address (when redirected to the on-link destination).
   ......

And the receive redirect function of ndisc_redirect_rcv() implemented
this definition, checks the target address correctly.
    if (ipv6_addr_equal(dest, target)) {
        on_link = 1;
    } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) {
        ND_PRINTK2(KERN_WARNING
               "ICMPv6 Redirect: target address is not link-local.\n");
        return;
    }

So, I think the send redirect function must check the target address
also.
