ARM: mvebu: Fix kernel hang in mvebu_soc_id_init() when of_iomap failed

2014-02-13T21:55:30+00:00

commit dc4910d9e93f8cc56b190dd8fc9e789135978216 upstream.

When pci_base is accessed whereas it has not been properly mapped by
of_iomap() the kernel hang. The check of this pointer made an improper
use of IS_ERR() instead of comparing to NULL. This patch fix this
issue.

ARM: orion: provide C-style interrupt handler for MULTI_IRQ_HANDLER

2014-02-13T21:55:30+00:00

commit f28d7de6bd4d41774744e011141945affa127da4 upstream.

DT-enabled Marvell Kirkwood and Dove SoCs make use of an irqchip
driver. As expected for irqchip drivers, it uses a C-style
interrupt handler and therefore selects MULTI_IRQ_HANDLER.

Now, compiling a kernel with both non-DT and DT support enabled,
selecting MULTI_IRQ_HANDLER will break ASM irq handler used by
non-DT boards.

Therefore, we provide a C-style irq handler even for non-DT boards,
if MULTI_IRQ_HANDLER is set. By installing the C-style irq handler
in orion_irq_init this is transparent to all non-DT board files.

While the regression report was filed on Marvell Kirkwood, also
Marvell Dove non-DT boards are affected and fixed by this patch.

ARM: mvebu: Add quirk for i2c for the OpenBlocks AX3-4 board

2014-02-06T19:34:07+00:00

commit 85e618a1be2b2092318178d1d66bdad49cbbeeeb upstream.

The first variants of Armada XP SoCs (A0 stepping) have issues related
to the i2c controller which prevent to use the offload mechanism and
lead to a kernel hang during boot.

This commit add quirk in the mvebu platform code to check the SoC
version and then update the compatible string for the i2c controller
according to the revision of the SoC. Currently only some OpenBlocks
AX3-4 boards are known to use an A0 revision so the check is done only
for these boards.

ARM: mvebu: Add support to get the ID and the revision of a SoC

2014-02-06T19:34:06+00:00

commit af8d1c63afcbf36eea06789c92e22d4af118d2fb upstream.

All the mvebu SoCs have information related to their variant and
revision that can be read from the PCI control register.

This patch adds support for Armada XP and Armada 370. This reading of
the revision and the ID are done before the PCI initialization to
avoid any conflicts. Once these data are retrieved, the resources are
freed to let the PCI subsystem use it.

Pull networking fixes from David Miller:

 1) The value choosen for the new SO_MAX_PACING_RATE socket option on
    parisc was very poorly choosen, let's fix it while we still can.
    From Eric Dumazet.

 2) Our generic reciprocal divide was found to handle some edge cases
    incorrectly, part of this is encoded into the BPF as deep as the JIT
    engines themselves.  Just use a real divide throughout for now.
    From Eric Dumazet.

 3) Because the initial lookup is lockless, the TCP metrics engine can
    end up creating two entries for the same lookup key.  Fix this by
    doing a second lookup under the lock before we actually create the
    new entry.  From Christoph Paasch.

 4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork.

 5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting.
    From Dan Carpenter.

 6) Netlink socket dumping uses the wrong socket state for timewait
    sockets.  Fix from Neal Cardwell.

 7) Fix netlink memory leak in ieee802154_add_iface(), from Christian
    Engelmayer.

 8) Multicast forwarding in ipv4 can overflow the per-rule reference
    counts, causing all multicast traffic to cease.  Fix from Hannes
    Frederic Sowa.

 9) via-rhine needs to stop all TX queues when it resets the device,
    from Richard Weinberger.

10) Fix RDS per-cpu accesses broken by the this_cpu_* conversions.  From
    Gerald Schaefer.

bpf: do not use reciprocal divide

2014-01-16T01:02:08+00:00

At first Jakub Zawadzki noticed that some divisions by reciprocal_divide
were not correct. (off by one in some cases)
http://www.wireshark.org/~darkjames/reciprocal-buggy.c

He could also show this with BPF:
http://www.wireshark.org/~darkjames/set-and-dump-filter-k-bug.c

The reciprocal divide in linux kernel is not generic enough,
lets remove its use in BPF, as it is not worth the pain with
current cpus.
