Michael Chan f78afb3563 bnx2x, cnic, bnx2i, bnx2fc: Fix bnx2i and bnx2fc regressions.
commit b9871bcfd2
    bnx2x: VF RSS support - PF side

changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i
and bnx2fc.  For the userspace driver, we need to pass a modified CID
so that the existing userspace driver will calculate the correct doorbell
address and continue to work.

Most users of get_cycles() invoke it as a timing interface.  That's why
in modern kernels it was never very much missed for.  /dev/random however
uses get_cycles() in the how the jitter in the interrupt timing contains

Tony Lindgren 775d2418f3 ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for blaze
Commit 76787b3b (ARM: OMAP2+: Remove board-4430sdp.c)
removed legacy booting in favor of device tree based booting
for 4430sdp. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.

I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp,
but the earlier version of this patch was tested by Luciano
Coelho. This version has left out the input logic for MMC CLK
line compared to the earlier version as that is not bidirectional,
and should be safe to do.

Tony Lindgren 851320e3f3 ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for pandaboard
Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c)
removed legacy booting in favor of device tree based booting
for pandaboard. That caused the WLAN to stop working as the
related .dts entries fell through the cracks.

The legacy muxing was setting pulls for GPIO 48 and 49, so let's
keep that behaviour for now to avoid further regressions for
BT and FM. Also input logic was enabled for MMC CLK line, but
I've verified that the input logic we don't need enabled for
CLK line as it's not bidirectional.

Also, we want to use non-removable instead of ti,non-removable
as the ti,non-removable also sets no_regulator_off_init which
is really not what we want as then wl12xx won't get powered
up and down which is needed for resetting it.

Note that looks like the WLAN interface fails to come up after
a warm reset, but that most likely was also happening with
the legacy booting and needs a separate fix.

Oleg Nesterov 03e1261778 tty: disassociate_ctty() sends the extra SIGCONT
Starting from v3.10 (probably commit f91e2590410b: "tty: Signal
foreground group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit.  This breaks LSB test-suite, in particular test8 in
_exit.c and test40 in sigcon5.c.

Put the "!on_exit" check back to restore the old behaviour.

Review by Peter Hurley:
 "Yes, this regression was introduced by me in that commit.  The effect
  of the regression is that ptys will receive a SIGCONT when, in similar
  circumstances, ttys would not.

  The fact that two test vectors accidentally tripped over this
  regression suggests that some other apps may as well.

  Thanks for catching this"

This fixes a multiplatform regression on the Ux500.

When compiling the Ux500 platforms in multiplatform configurations
both PL310_ERRATA_588369 and PL310_ERRATA_727915 would crash the
platform when trying to launch the init process.

The Ux500 cannot access the debug registers of the PL310, it will
just crash if you try this. So disable this by setting the debug
callback to NULL when initializing the l2x0 on this platform.

Koen Kooi 2ba3549352 ARM: dts: am335x-bone*: add DT for BeagleBone Black
The BeagleBone Black is basically a regular BeagleBone with eMMC and
HDMI added, so create a common dtsi both can use.

IMPORTANT: booting the existing am335x-bone.dts will blow up the HDMI
transceiver after a dozen boots with an uSD card inserted because LDO
will be at 3.3V instead of 1.8.

MMC support for AM335x still isn't in, so only the LDO change has been
added.

Ralf Baechle c5f6659631 MIPS: Provide nice way to access boot CPU's data.
boot_cpu_data is used the same as current_cpu_data but returns the CPU
data for CPU 0.  This means it doesn't have to use smp_processor_id()

Paolo Bonzini ba6a354154 KVM: mmu: allow page tables to be in read-only slots
Page tables in a read-only memory slot will currently cause a triple
fault because the page walker uses gfn_to_hva and it fails on such a slot.

OVMF uses such a page table; however, real hardware seems to be fine with
that as long as the accessed/dirty bits are set.  Save whether the slot
is readonly, and later check it when updating the accessed and dirty bits.

Aaro Koskinen 7cc4fa1e51 staging: octeon-ethernet: rgmii: enable interrupts that we can handle
Enable only those interrupts that we can handle & acknowledge in the
interrupt handler.

At least on EdgeRouter Lite, the hardware may occasionally interrupt with
some error condition when the physical link status changes frequently.
Since the interrupt condition is not acked properly, this leads to the
following warning and the IRQ gets disabled completely:

Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2
Workaround: The only workaround to this erratum is to disable the
double linefill feature. This is the default behavior.
