commit c7ac8679bec9397afe8918f788cbcef88c38da54 upstream. The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request.

Hi, Jens, If you recall, I posted an RFC patch for this back in July of last year: http://lkml.org/lkml/2010/7/13/279 The basic problem is that a process can issue a never-ending stream of async direct I/Os to the same sector on a device, thus starving out other I/O in the system (due to the way the alias handling works in both cfq and deadline). The solution I proposed back then was to start dispatching from the fifo after a certain number of aliases had been dispatched. Vivek asked why we had to treat aliases differently at all, and I never had a good answer. So, I put together a simple patch which allows aliases to be added to the rb tree (it adds them to the right, though that doesn't matter as the order isn't guaranteed anyway). I think this is the preferred solution, as it doesn't break up time slices in CFQ or batches in deadline. I've tested it, and it does solve the starvation issue. Let me know what you think.

The display MIX can be power gated when EPDC, PXP and LCDIF are all inactive. This will save around 1.5mW-1.8mW of power in system IDLE mode. Need to re-initialize the EPDC and PXP whenever the display MIX is powered up as all the register state is lost when the display MIX is power gated.

Add a command line option to route the ENET interrupts to the GPIO_1_6. To route the ENET interrupts to GPIO_6 add "enet_gpio_6" to the kernel command line. Also remove the CONFIG option (MX6_ENET_IRQ_TO_GPIO).
