We need to separate the two because the heap of a PIE is created in
the area to which it is mapped.

Add the following patterns of symlinks:
- /sys/bus/cpu/drivers/processor/cpu*
- /sys/bus/node/devices/node*
And slightly change how /sys/devices/system/cpu/cpu*/node* are created
to avoid duplicate lookups

Its call site is moved before numa_init() as well because
monitor_init() defines ihk_os_monitor that was used in
rusage_total_memory_add() called from numa_init().
I didn't revert this modification because I don't want to touch the
working code.

Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

some archs do not have the simple open/unlink variants, while the *at
is always available -- this is simpler than making these arch-dependent
functions

init_linux_kernel_mapping is called in setup_x86_phase1 way
before arguments are setup, but we can access kernel boot args
directly and use that, so ugly fix for now.

ihk_ikc_release_packet takes the channel and puts the packet into its
free-list. This fix makes it easy and safe to identify the proper
channel.

In arm64, glibc-open of /dev/xpmem is hooked in sys_openat. This
commit adds xpmem_openat which is called by sys_openat.
This commit silently applies copy_from_user fix to sys_open as well.

Since McKernel allocates hugepages by default, we could consider that
madvise call with MADV_HUGEPAGE is supported.

envs are stuck after args which are now possibly unaligned, and used
from a non-aligned pointer in prepare_process_ranges_args_envs (env)
The memory immediately after args/envs is copied anyway with memcpy_long,
so make sure the bits are initialized and realign env correctly
Fixes: 70e52faf36 ("flatten_strings: do not return unused trailing bits")

Add "-T 0" to mcreboot.sh if you want to turn off time sharing. When

length of per-CPU run-queue is larger than one.
