Paul Burton e14f1db7a6 MIPS: AT_HWCAP aux vector infrastructure ... In order for userland to determine whether various features are safe to use, it will need to know both that the hardware supports those features and that the kernel is recent enough & configured appropriately to support them. For example under the O32 modeless FP proposal the dynamic linker & ifunc resolvers will need this information. The kernel is the only thing in a position to know availability accurately, so the kernel needs to provide the information to userland. This patch introduces the infrastructure to provide the AT_HWCAP aux vector to userland in order to provide that information. It also defines the 2 currently specified flags, which indicate MIPSr6 & MSA support.
