# commit 3281366a8e79a512956382885091565db1036b64
# Author: Peter Bergner <bergner@linux.ibm.com>

#     uapi/auxvec: Define AT_HWCAP3 and AT_HWCAP4 aux vector, entries
#     
#     The powerpc toolchain keeps a copy of the HWCAP bit masks in the TCB
#     for fast access by the __builtin_cpu_supports() built-in function. The
#     TCB space for the HWCAP entries - which are created in pairs - is an ABI
#     extension, so waiting to create the space for HWCAP3 and HWCAP4 until
#     they are needed is problematic. Define AT_HWCAP3 and AT_HWCAP4 in the
#     generic uapi header so they can be used in glibc to reserve space in the
#     powerpc TCB for their future use.
#     
#     I scanned through the Linux and GLIBC source codes looking for unused
#     AT_* values and 29 and 30 did not seem to be used, so they are what I
#     went with.
