c84470dda7 xfs: remove leftovers of the old btree tracing code
Remove various bits left over from the old kdb-only btree tracing code, but
leave the actual trace point stubs in place to ease adding new event based
btree tracing.

ea15ab3cdd xfs: remove the dead QUOTADEBUG code
Remove the dead hash table test rid which has been rotting away under
QUOTADEBUG, including some code that was compiled for normal debug
builds, but not actually called without QUOTADEBUG, and enable a few
cheap debug checks that were hidden under QUOTADEBUG for normal
debug builds.

bf9d9013a2 xfs: add a proper transaction pointer to struct xfs_buf
Replace the typeless b_fspriv2 and the ugly macros around it with a properly
typed transaction pointer.  As a fallout the log buffer state debug checks
are also removed.  We could have kept them using casts, but as they do
not have a real purpose we can as well just remove them.

5792664070 xfs: reshuffle dir2 headers
Replace the current mess of dir2 headers with just three that have a clear
purpose:

 - xfs_dir2_format.h for all format definitions, including the inline helpers
   to access our variable size structures
 - xfs_dir2_priv.h for all prototypes that are internal to the dir2 code
   and not needed by anything outside of the directory code.  For this
   purpose xfs_da_btree.c, and phase6.c in xfs_repair are considered part
   of the directory code.
 - xfs_dir2.h for the public interface to the directory code

In addition to the reshuffle I have also update the comments to not only
match the new file structure, but also to describe the directory format
better.

2bcf6e970f xfs: start periodic workers later
Start the periodic sync workers only after we have finished xfs_mountfs
and thus fully set up the filesystem structures.  Without this we can
call into xfs_qm_sync before the quotainfo strucute is set up if the

as well.

390fd0b388 slip: remove dead code within the slip initialization
This following code contains a dead "if (dev).." block:
        ...
        for (i = 0; i < slip_maxdev; i++) {
                dev = slip_devs[i];
                if (dev == NULL)
                        break;
        }
        /* Sorry, too many, all slots in use */
        if (i >= slip_maxdev)
                return NULL;

        if (dev) {
                sl = netdev_priv(dev);
                if (test_bit(SLF_INUSE, &sl->flags)) {
                        unregister_netdevice(dev);
                        dev = NULL;
                        slip_devs[i] = NULL;
                }
         }
        ...
The reason is that the code starting with "if (dev).." is never called as
when we found an empty slot (dev == NULL) we break the loop and "if (dev).."
not works eiter the loop ends and we get out with "i >= slip_maxdev".

5c25f686db net: Kill support for multiple hh_cache entries per neighbour

Neighbour entries are always tied to one address family, and therefore
one set of dst_ops, and therefore one dst_ops->protocol "hh_type"
value.

7653aaab77 drivers/video: use strings to specify the Freescale DIU monitor port
Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow
the user to specify the port by name ("dvi", "lvds", or "dlvds").  This works
on the kernel command line, the module command-line, and the sysfs "monitor"
device.

Note that changing the monitor port does not currently work on the P1022DS,
because the code that talks to the PIXIS FPGA is broken.

c6daf05b6d video: da8xx-fb: Interrupt configuration of revised LCDC IP
An upcoming SoC of TI comes with an LCD controller which is an updated
version of that found on TI's DA850 SoC. The da8xx-fb driver can support
this LCD with some enhancements.
This patch adds support for updated interrupt configuration on the new
SoC.
1) Registers for setting and clearing interrupts are different.
2) Raw and masked status registers are different.
The updates have been tested on an emulation platform for new features
and the patch has been tested on DA850 platform to make sure nothing
existing breaks.

b63d10130e drivers/video/udlfb match class, subclass, and protocol
Match udlfb only against vendor-specific class (e.g. only DisplayLink
graphics, not composite standard audio class interfaces). This enables
compatibility with composite graphics+audio devices (e.g. HDMI).

Match udlfb only against compatible subclass 0 and protocol 0 chips.
DisplayLink's USB 3.0 generation chips increment these values
to signal that they have a incompatible protocol, preventing udlfb
from erroneously matching to hardware it does not support.

Tested to confirm proper behavior on both USB 2.0 and USB 3.0
generation devices.

c84c14224b carminefb: Fix module parameters permissions
The third parameter of module_param is supposed to be an octal value.
The missing leading "0" causes the following:

$ ls -l /sys/module/carminefb/parameters/
total 0
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_displays
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_mode
-rw-rwxr-- 1 root root 4096 Jul  8 08:55 fb_mode_str

After fixing the perm parameter, we get the expected:

$ ls -l /sys/module/carminefb/parameters/
total 0
-r--r--r-- 1 root root 4096 Jul  8 08:56 fb_displays

1e01979c8f x86, numa: Implement pfn -> nid mapping granularity check
SPARSEMEM w/o VMEMMAP and DISCONTIGMEM, both used only on 32bit, use
sections array to map pfn to nid which is limited in granularity.  If
NUMA nodes are laid out such that the mapping cannot be accurate, boot
will fail triggering BUG_ON() in mminit_verify_page_links().

On 32bit, it's 512MiB w/ PAE and SPARSEMEM.  This seems to have been
granular enough until commit 2706a0bf7b (x86, NUMA: Enable
CONFIG_AMD_NUMA on 32bit too).  Apparently, there is a machine which
aligns NUMA nodes to 128MiB and has only AMD NUMA but not SRAT.  This
led to the following BUG_ON().

This patch implements node_map_pfn_alignment() which determines
maximum internode alignment and update numa_register_memblks() to
reject NUMA configuration if alignment exceeds the pfn -> nid mapping
granularity of the memory model as determined by PAGES_PER_SECTION.

This makes the problematic machine boot w/ flatmem by rejecting the
NUMA config and provides protection against crazy NUMA configurations.

d0ead15738 x86, mm: s/PAGES_PER_ELEMENT/PAGES_PER_SECTION/
DISCONTIGMEM on x86-32 implements pfn -> nid mapping similarly to
SPARSEMEM; however, it calls each mapping unit ELEMENT instead of
SECTION.  This patch renames it to SECTION so that PAGES_PER_SECTION
is valid for both DISCONTIGMEM and SPARSEMEM.  This will be used by
the next patch to implement mapping granularity check.

This patch is trivial constant rename.

listing in th e"REAL-MODE KERNEL HEADER" section. It is listed as 0x25c in
