2014-07-24crypto: ccp - Remove "select OF" from KconfigTom Lendacky
The addition of the "select OF if ARM64" has led to a Kconfig recursive dependency error when "make ARCH=sh rsk7269_defconfig" was run. Since OF is selected by ARM64 and the of_property_read_bool is defined no matter what, delete the Kconfig line that selects OF.

Revert half of commit d151f9854f21: If isochronous I/O is attempted with packets larget than 1 kByte, VIA VT6315 rev 01 immediately stops to generate any interrupts if MSI are used. Fix this by going back to legacy interrupts. [Thread "Isochronous streaming with VT6315 OHCI", http://marc.info/?t=139049641500003] With smaller packets, the loss of IRQs happens too but only very rarely --- rarely eneough that it was not yet possible for me to determine whether QUIRK_NO_MSI is an actual fix for this rare variation of this chip bug. I am keeping QUIRK_CYCLE_TIMER off of VT6315 rev >= 1 because this has been verified by myself with certainty. On the other hand, I am also keeping QUIRK_CYCLE_TIMER on for VT6315 rev 0 because I don't know at this time whether this revision accesses Cycle Timer non-atomically like most of the other VIA OHCIs are known to do.

An object can only have an active gtt mapping if it is currently bound into the global gtt. Therefore we can simply walk the list of all bound objects and check the flag upon those for an active gtt mapping.

Rather it is the caller that relies upon this condition and so it should assert that the GPU is idle itself.

2014-07-23crypto: ccp - Base AXI DMA cache settings on device treeTom Lendacky
The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the ccp driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-07-22net: bcmgenet: correctly pad short packetsFlorian Fainelli
Packets shorter than ETH_ZLEN were not padded with zeroes, hence leaking potentially sensitive information. This bug has been present since the driver got accepted in commit 1c1008c793fa46703a2fee469f4235e1c7984333 ("net: bcmgenet: add main driver file").
