ad1b6d85ba Remove kernel-features.h conditionals on pre-3.2 kernels. 
This patch follows up on the increase in minimum kernel version by
removing conditionals in non-x86, non-x86_64 kernel-features.h headers
that are now constant for all supported kernel versions.

f4491417cc Call direct system calls for socket operations 
Explicit system calls for the socket operations were added in Linux kernel
in commit 86250b9d12ca for powerpc. This patch make use of those instead of
calling socketcall to save number of cycles on networking syscalls.

be481652f2 Remove __ASSUME_IPC64 
PowerPC has always used __IPC_64 like most other architectures, which
means that __ASSUME_IPC64 can be always true.  Also, all other
architecture implementations that use the ipc syscall are effectively
identical to the generic version and can be removed.
