[Bug nptl/19313] Wrong __cpu_mask for x32

--- Comment #2 from cvs-commit at gcc dot <cvs-commit at gcc dot> ---
This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".

commit 7635a88d320c665defd44085d3b9031d673fe1ee

    Add __CPU_MASK_TYPE for __cpu_mask

    Since x86-64 and x32 use the same set of sched_XXX system call interface:

    [hjl@gnu-6 linux-stable]$ grep sched_
    24  common  sched_yield             sys_sched_yield
    142 common  sched_setparam          sys_sched_setparam
    143 common  sched_getparam          sys_sched_getparam
    144 common  sched_setscheduler      sys_sched_setscheduler
    145 common  sched_getscheduler      sys_sched_getscheduler
    146 common  sched_get_priority_max  sys_sched_get_priority_max
    147 common  sched_get_priority_min  sys_sched_get_priority_min
    148 common  sched_rr_get_interval   sys_sched_rr_get_interval
    203 common  sched_setaffinity       sys_sched_setaffinity
    204 common  sched_getaffinity       sys_sched_getaffinity
    314 common  sched_setattr           sys_sched_setattr
    315 common  sched_getattr           sys_sched_getattr
    [hjl@gnu-6 linux-stable]$

    __cpu_mask should be unsigned long long, instead of unsigned long, for
    x32.  This patch adds __CPU_MASK_TYPE so that each architecture can
    define the proper type for __cpu_mask.

        [BZ #19313]
        * bits/typesizes.h (__CPU_MASK_TYPE): New.
        * sysdeps/mach/hurd/bits/typesizes.h (__CPU_MASK_TYPE): Likewise.
        * sysdeps/nacl/bits/typesizes.h (__CPU_MASK_TYPE): Likewise.
        * sysdeps/unix/sysv/linux/alpha/bits/typesizes.h (__CPU_MASK_TYPE):
        * sysdeps/unix/sysv/linux/generic/bits/typesizes.h (__CPU_MASK_TYPE):
        * sysdeps/unix/sysv/linux/s390/bits/typesizes.h (__CPU_MASK_TYPE):
        * sysdeps/unix/sysv/linux/sparc/bits/typesizes.h (__CPU_MASK_TYPE):
        * sysdeps/unix/sysv/linux/x86/bits/typesizes.h (__CPU_MASK_TYPE):
        * sysdeps/unix/sysv/linux/bits/sched.h (__cpu_mask): Replace
        unsigned long int with __CPU_MASK_TYPE.
