e757e3e198 ixgbevf: Make next_to_watch a pointer and adjust memory barriers to avoid races
This change is meant to address several race issues that become possible
because next_to_watch could possibly be set to a value that shows that the
descriptor is done when it is not.  In order to correct that we instead make
next_to_watch a pointer that is set to NULL during cleanup, and set to the
eop_desc after the descriptor rings have been written.

To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit.  In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.

5f3347e6e7 bnx2x: Fix intermittent long KR2 link up time
When a KR2 device is connected to a KR link-partner, sometimes it requires
disabling KR2 for the link to come up. To get a KR2 link up later, in case no
base pages are seen, the KR2 is restored. The problem was that some link
partners cleared their advertised BP/NP after around two seconds, causing the
driver to disable/enable KR2 link all the time.
The fix was to wait at least 5 seconds before checking KR2 recovery.

36c1813bb4 drm/tegra: drop "select DRM_HDMI"
Commit ac24c2204a ("drm/tegra: Use generic
HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA
Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select
statement for that symbol is a nop. Drop it.

What was needed to use HDMI functionality was to select HDMI (which this
entry already did through depending on DRM) and to include linux/hdmi.h
(which this commit also did).

ce495960ff drm/mgag200: Bug fix: Renesas board now selects native resolution.
Renesas boards were consistently defaulting to the 1024x768 resolution,
regardless of the native resolution of the monitor plugged in.  It was
determined that the EDID of the monitor was not being read.  Since the
DAC is a shared line, in order to read from or write to it we must take
control of the DAC clock.  This can be done by setting the proper
register to one.

This bug fix sets the register MGA1064_GEN_IO_CTL2 to one.  The DAC
control line can be used to determine whether or not a new monitor has
been plugged in.  But since the hotplug feature is not one we will
support, it has been decided to simply leave the register set to one.

c10cb5fc0f Fix: sparse warning in inet_csk_prepare_forced_close
In e337e24d66 (inet: Fix kmemleak in tcp_v4/6_syn_recv_sock and
dccp_v4/6_request_recv_sock) I introduced the function
inet_csk_prepare_forced_close, which does a call to bh_unlock_sock().
This produces a sparse-warning.

This patch adds the missing __releases.

60f583d56a x86: Do not try to sync identity map for non-mapped pages
kernel_map_sync_memtype() is called from a variety of contexts.  The
pat.c code that calls it seems to ensure that it is not called for
non-ram areas by checking via pat_pagerange_is_ram().  It is important
that it only be called on the actual identity map because there *IS*
no map to sync for highmem pages, or for memory holes.

The ioremap.c uses are not as careful as those from pat.c, and call
kernel_map_sync_memtype() on PCI space which is in the middle of the
kernel identity map _range_, but is not actually mapped.

This patch adds a check to kernel_map_sync_memtype() which probably
duplicates some of the checks already in pat.c.  But, it is necessary
for the ioremap.c uses and shouldn't hurt other callers.

I have reproduced this bug and this patch fixes it for me and the
original bug reporter:

0c1233aba1 netlabel: correctly list all the static label mappings
When we have a large number of static label mappings that spill across
the netlink message boundary we fail to properly save our state in the
netlink_callback struct which causes us to repeat the same listings.
This patch fixes this problem by saving the state correctly between
calls to the NetLabel static label netlink "dumpit" routines.

When autoneg has been disabled in the PHY (Marvell 88E1118 here), auto

way I found to workaround this is to manually configure the MAC with the

The kernel calls `vxlan_exit_net` when deleting the netns before shutting down
vxlan interfaces. Later the removal of all vxlan interfaces, where `vn->sock`
is already gone causes the oops. so we should manually shutdown all interfaces
before deleting `vn->sock` as the patch does.
