This extends the x86 copy of the sysvipc data structures to deal with

Fortunately, x86 has padding for this purpose in all the data structures,

32-bit architectures implementing 64BIT_TIME and COMPAT_32BIT_TIME
need to have the traditional semtimedop() behavior with 32-bit timestamps
for sys_ipc() by calling compat_ksys_semtimedop(), while those that
are not yet converted need to keep using ksys_semtimedop() like
64-bit architectures do.
This is a preparatation for changing over __kernel_timespec to 64-bit
times, which involves assigning new system call numbers for mq_timedsend(),
mq_timedreceive() and semtimedop() for compatibility with future y2038
proof user space.
The existing ABIs will remain available through compat code.

Perf doesn't support mixed events from different PMUs (except software
event) in a group. The perf stat should output / for all events, but it doesn't. For example,

The 'perf stat' fallback for EACCES error sets the exclude_kernel

it also changes the name of the event to reflect that change by adding
the 'u' modifier.

map_groups__fixup_end() was called to set the end addresses of kernel

Now that 32-bit architectures have two variants of
sys_rt_sigtimedwaid() for 32-bit and 64-bit time_t, we also
need to have a second compat system call entry point on the
corresponding 64-bit architectures.
The traditional system call keeps getting handled
by compat_sys_rt_sigtimedwait(), and this
This is a preparation patch for converting sys_sched_rr_get_interval to
work with 64-bit time_t on 32-bit architectures. The 'interval' argument
is changed to struct __kernel_timespec, which will be redefined using
64-bit time_t in the future. The compat version of the system call in
turn is enable
