Pull s390 updates from Heiko Carstens:

 - Add support for the hugetlb_cma command line option to allocate
   gigantic hugepages using CMA

 - Add arch_get_random_long() support.

 - Add ap bus userspace notifications.

 - Increase default size of vmalloc area to 512GB and otherwise let it
   increase dynamically by the size of physical memory. This should fix
   all occurrences where the vmalloc area was not large enough.

 - Completely get rid of set_fs() (aka select SET_FS) and rework address
   space handling while doing that; making address space handling much
   more simple.

 - Reimplement getcpu vdso syscall in C.

 - Add support for extended SCLP responses (&gt; 4k). This allows e.g. to
   handle also potential large system configurations.

 - Simplify KASAN by removing 3-level page table support and only
   supporting 4-levels from now on.

 - Improve debug-ability of the kernel decompressor code, which now
   prints also stack traces and symbols in case of problems to the
   console.

 - Remove more power management leftovers.

 - Other various fixes and improvements all over the place.

<content type='text'>
The UML random driver creates a dummy device under the guest,
/dev/hw_random. When this file is read from the guest, the driver
reads from the host machine's /dev/random, in-turn reading from
the host kernel's entropy pool. This entropy pool could have been
filled by a hardware random number generator or just the host
kernel's internal software entropy generator.

Currently the driver does not fill the guests kernel entropy pool,
this requires a userspace tool running inside the guest (like
rng-tools) to read from the dummy device provided by this driver,
which then would fill the guest's internal entropy pool.

This all seems quite pointless when we are already reading from an
entropy pool, so this patch aims to register the device as a hwrng
device using the hwrng-core framework. This not only improves and
cleans up the driver, but also fills the guest's entropy pool
without having to resort to using extra userspace tools in the guest.

This is typically a nuisance when booting a guest: the random pool
takes a long time (~200s) to build up enough entropy since the dummy
hwrng is not used to fill the guest's pool.

This port was originally attempted by Alexander Neville "dark" (in CC,
discussion in Link), but the conversation there stalled since the
handling of -EAGAIN errors were no removed and longer handled by the
driver. This patch attempts to use the existing method of error
handling but utilises the new hwrng core.

The issue can be noticed when booting a UML guest:

    [    2.560000] random: fast init done
    [  214.000000] random: crng init done

With the patch applied, filling the pool becomes a lot quicker:

    [    2.560000] random: fast init done
    [   12.000000] random: crng init done
