After a bus reset, let nodemgr call high-level update hooks first for nodes
which do not need to be probed.  The main benefit is for a bus with more

logins, thus have a much higher chance to succeed, and their SCSI devices
will not be blocked much longer than necessary.  This was demonstrated for
Linux 2.4 by Dave Cinege a while ago.

subthread.  I actually plan to implement this for sbp2 but it may take a

Commit f549d6c18c0e8e6cf1bf0e7a47acc1daf7e2cec1 introduced a generic
fallback for security xattrs, but appears to include a subtle bug.

Gentoo users with kernels with selinux compiled in, and coreutils compiled
with acl support, noticed that they could not copy files on tmpfs using
'cp'.

cp (compiled with acl support) copies the file, lists the extended
attributes on the old file, copies them all to the new file, and then
exits.  However the listxattr() calls were failing with this odd behaviour:

llistxattr("a.out", (nil), 0)           = 17
llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of
range)

I believe this is a simple problem in the logic used to check the buffer
sizes; if the user sends a buffer the exact size of the data, then its ok
:)

This change solves the problem.

[ARM] 3200/1: Singlestep over ARM BX and BLX instructions using ptrace fix

Patch from Nikola Valerjev

Single stepping an application using ptrace() fails over ARM instructions BX and BLX.

Steps to reproduce:

Compile and link the following files

main.c
-----
void foo();
int main() {
    foo();
    return 0;
}

foo.s
-----
.text
.globl foo
foo:
BX LR

Using ptrace() functionality, run to main(), and start singlestepping.
Singlestep over \"BX LR\" instruction won\'t transfer the control back
to main, but run the code to completion.

This problems seems to be in the function get_branch_address() in
arch/arm/kernel/ptrace.c. The function doesn\'t seem to recognize BX
and BLX instructions as branches. BX and BLX instructions can be used
to convert from ARM to Thumb mode if the target address has the low
bit set. However, they are also perfectly legal in the ARM only mode.
Although other things in the kernel seem to indicate that only ARM
mode is accepted (and not Thumb), many compilers will generate BX
and BLX instructions even when generating ARM only code.

On most powerpc CPUs, the dcache and icache are not coherent so
between writing and executing a page, the caches must be flushed.
Userspace programs assume pages given to them by the kernel are icache
clean, so we must do this flush between the kernel clearing a page and
it being mapped into userspace for execute.  We were not doing this
for hugepages, this patch corrects the situation.

We use the same lazy mechanism as we use for normal pages, delaying
the flush until userspace actually attempts to execute from the page
in question.

[PATCH] powerpc: Set cache info defaults

Cache info is setup by walking the device tree in initialize_cache_info().
However, icache_flush_range might be called before that, in
slb_initialize()->patch_slb_encoding, which modifies the load immediate
instructions used with SLB fault code.

Not only that, but depending on memory layout, we might take SLB faults
during unflatten_device_tree. So that fault will load an SLB entry that
might not contain the right LLP flags for the segment.

Either we can walk the flattened device tree to setup cache info, or
we can pick the known defaults that are known to work. Doing it in the
flattened device tree is hairier since we need to know the machine type
to know what property to look for, etc, etc.

For now, it's just easier to go with the defaults. Worst thing that
happens from it is that we might waste a few cycles doing too small
