95d751feac libc: Add ftruncate64 and improve 64-bit parameter syscall handling. 
This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.

This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().

Also add ftruncate64() to <unistd.h>

72e6fd4242 <sched.h>: Add sched_getcpu() and cpu_set_t 
This adds the cpu_set_t type definition and related functions
and macros used to handle CPU thread affinity.

  sched_getcpu()
  sched_setaffinity()
  sched_getaffinity()

e4fa46e75c Set SA_RESTORER in sigaction() 
GDB looks for specific opcode sequences when trying to recognize a stack
frame as a signal trampoline.  The sequences it looks for happen to be those
created when SA_RESTORER is set, since glibc always sets a restorer.  This
patch does the same here, so that the trampolines can be correctly identified.

9f6915631b bonic: libc: cpuacct support for setuid functions 
Any of the setuid functions now updates /acct/uid/ with its own tid
before changing users. This is so we can properly account for cpu time
per uid.

97cf7f3394 Implement clone() C library function properly. 
Only provide an implementation for ARM at the moment, since
it requires specific assembly fragments (the standard syscall
stubs cannot be used because the child returns in a different
stack).
