In the TT_RESPONSE packet, the number of carried entries is not correctly set.
This leads to a wrong interpretation of the packet payload on the receiver side
causing random entries to be added to the global translation table. Therefore
the latter gets always corrupted, triggering a table recovery all the time.

Currently the counter of tt_local_entry structures (tt_local_num) is incremented
each time the tt_local_reset_flags() is invoked causing the node to send wrong
TT_REPONSE packets containing a copy of non-initialised memory thus corrupting
other nodes global translation table and making higher level communication
impossible.

Some Stellaris evaluation kits have the JTAG/SWD FTDI chip onboard,
and some, like EK-LM3S9B90, come with a separate In-Circuit Debugger
Interface Board. The ICDI board can also be used stand-alone, for
other boards and chips than the kit it came with. The ICDI has both
old style 20-pin JTAG connector and new style JTAG/SWD 10-pin 1.27mm
pitch connector.
Tested with EK-LM3S9B90, where the BD-ICDI board is included.

At least some OHCI hardware (such as the MCP89) fails to flag any change
in the host status register or the port status registers when receiving
a remote wakeup while in D3 state. This results in the controller being
resumed but no device state change being noticed, at which point the
controller is put back to sleep again. Since there doesn't seem to be any
reliable way to identify the state change, just unconditionally resume the
hub. It'll be put back to sleep in the near future anyway if there are no
active devices attached to it.

To add USB 3.0 link power management (LPM), we need to know what the U1
and U2 exit latencies are for the xHCI host controller. External USB 3.0
hubs report these values through the SuperSpeed Capabilities descriptor in
the BOS descriptor. Make the USB 3.0 roothub for the xHCI host behave
like an external hub and return the BOS descriptors.
The U1 and U2 exit latencies will vary across each host controller, so we
need to dynamically fill those values in by reading the exit latencies out
of the xHC registers. Make the roothub code in the USB core handle
hub_control() returning the length of the data copied.

We can't have color correctly set there because in libslang (and in a future

The selection and scroll bar are really needed only when the user starts
navigating, before that it just provide distractions.
This also brings the initial screen to look more like the stdio UI,
which more people are used to.
The new code is flexible enough that menu like browsers can opt out and
start with those UI elements.

Dynamic debug recently added support for netdev_printk. It uses
__netdev_printk() to support this functionality. However, when CONFIG_NET
is not set, we get the following error:
lib/built-in.o: In function `__dynamic_netdev_dbg':
(.text+0x9fda): undefined reference to `__netdev_printk'
Fix this by making the call to netdev_printk() contingent upon CONFIG_NET.
We could have fixed this by defining netdev_printk() to a 'no-op' in the
!CONFIG_NET case. However, this is not consistent with how the networking
layer uses netdev_printk. For example, CONFIG_NET is not set,
netdev_printk() does not have a 'no-op' definition defined.

We were using KERN_CONT to combine messages with their prefix. However,
KERN_CONT is not smp safe, in the sense that it can interleave messages.
This interleaving can result in printks coming out at the wrong loglevel.
With the high frequency of printks that dynamic debug can produce this is
not desirable.
So make dynamic_emit_prefix() fill a char buf[64] instead of doing a
printk directly. If we enable printing out of function, module, line, or
pid info, they are placed in this 64 byte buffer. In my testing 64 bytes
was enough size to fulfill all requests. Even if it's not, we can match
up the printk itself to see where it's from, so to me this is no big deal.

To support >32-bit physical addresses for UIO_MEM_PHYS type we need to
extend the width of 'addr' in struct uio_mem. Numerous platforms like
embedded PPC, ARM, and X86 have support for systems with larger physical
address than logical.
Since 'addr' may contain a physical, logical, or virtual address the
easiest solution is to just change the type to 'phys_addr_t' which
should always be greater than or equal to the sizeof(void *) such that
it can properly hold any of the address types.
For physical address we can support up to a 44-bit physical address on a
typical 32-bit system as we utilize remap_pfn_range() for the mapping of
the memory region and pfn's are represnted by shifting the address by
the page size (typically 4k).

readlink() never zero terminates the provided buffer.
Therefore we already do
buffer[count] = 0;
This leads to an off-by-one buffer corruption as readlink()
might return the full size of the buffer.
The common technique is to reduce the buffer size by one.
Another fix would be to check
if (count < 0 || count == sizeof(buffer))
fatal();
Reducing the buffer size by one is easier IMHO.

commit ae50c0b5 "pnfs: client stats" added additional information to
the output of /proc/self/mountstats. The new functions introduced are
only used in this file and should be marked static.
If CONFIG_NFS_V4_1 is not defined, empty stub functions are used. If
CONFIG_NFS_V4 is not defined these stub functions are not used at all.
Adding static for the functions results in compile warnings:
fs/nfs/super.c:743: warning: 'show_sessions' defined but not used
fs/nfs/super.c:756: warning: 'show_pnfs' defined but not used
Fix this by adding a #ifdef CONFIG_NFS_V4 guard around the two
show_ functions.

nfs_find_and_lock_request will take a reference to the nfs_page and
will then put it if the req is already locked. It's possible though
that the reference will be the last one. That put then can kick off
a whole series of reference puts:
nfs_page
nfs_open_context
dentry
inode
If the inode ends up being deleted, then the VFS will call
truncate_inode_pages. That function will try to take the page lock, but
it was already locked when migrate_page was called. The code
deadlocks.
Fix this by simply refusing the migration request if PagePrivate is
already set, indicating that the page is already associated with an
active read or write request.
We've had a customer test a backported version of this patch and
the preliminary results seem good.

commit 420e3646 allowed the kernel to reduce the number of unnecessary
commit calls by skipping the commit when there are a large number of
outstanding pages.
However, the current test in nfs_commit_unstable_pages does not handle
the edge condition properly. When ncommit == 0, then that means that the
kernel doesn't need to do anything more for the inode. The current test
though in the WB_SYNC_NONE case will return true, and the inode will end
up being marked dirty. Once that happens the inode will never be clean
until there's a WB_SYNC_ALL flush.
Fix this by immediately returning from nfs_commit_unstable_pages when
ncommit == 0.
Mike noticed this problem initially in RHEL5 (2.6.18-based kernel) which
has a backported version of 420e3646. The inode cache there was growing
very large. The inode cache was unable to be shrunk since the inodes
were all marked dirty. Calling sync() would essentially "fix" the
problem -- the WB_SYNC_ALL flush would result in the inodes all being
marked clean.
What I'm not clear on is how big a problem this is in mainline kernels
as the writeback code there is very different. Either way, it seems
incorrect to re-mark the inode dirty in this case.

This reverts commit b80c3cb628f0ebc241b02e38dd028969fb8026a2.
The reverted commit was rendered obsolete by a VFS fix: commit
5547e8aac6f71505d621a612de2fca0dd988b439 (writeback: Update dirty flags in
two steps). We now no longer need to worry about writeback_single_inode()
missing our marking the inode for COMMIT in 'do_writepages()' call.
Reverting this patch, fixes a performance regression in which the inode
would continuously get queued to the dirty list, causing the writeback
code to unnecessarily try to send a COMMIT.

The intent here was to return an error code, but instead the code
returns the number of bytes remaining (that weren't copied).
