linux-next: Tree for Jan 29

Hi all, Changes since 20160128: The gpio tree gained a build failure so I used the version from next-20160128. The aio tree still had a build failure so I used the version from next-20160111. I added 2 supplied patches to the akpm-current tree to fix build problems. Non-merge commits

[RESEND PATCH v4] x86/PCI: Recognize that Interrupt Line 255 means "not connected"

Per the x86-specific footnote to PCI spec r3.0, sec 6.2.4, the value 255 in the Interrupt Line register means "unknown" or "no connection." Previously, when we couldn't derive an IRQ from the _PRT, we fell back to using the value from Interrupt Line as an IRQ. It's questionable whether we should d

Re: [RFC][PATCH] seccomp: add SECCOMP_RET_ACK for non-fatal SIGSYS

Thanks! This is just what I need. What are the drawbacks to returning the sigsys before executing the system call? Otherwise this loses the benefit of properly reporting registers for argument inspection. How about SECCOMP_RET_PERMISSIVE? Describes the application rather than the implementation.

Clearing of the pages on free provides an increase in security as it helps to limit the risk of information leaks. Allow page poi

[PATCHv2 2/2] mm/page_poisoning.c: Allow for zero poisoning

By default, page poisoning uses a poison value (0xaa) on free. If this is changed to 0, the page is not only sanitized but zeroing on alloc with __GFP_ZERO can be skipped as well. The tradeoff is that detecting corruption from the poisoning is harder to detect. This feature also cannot be used with
