There's a couple fixes for the recent LDT remap placement change.
The first patch fixes crash when kernel booted as Xen dom0.
The second patch fixes address space markers in dump_pagetables output.
It's purely cosmetic change, backporting to the stable tree is optional.

LZO leaves some performance on the table by not realising that arm64 can
optimize count-trailing-zeros bit operations.
Add CONFIG_ARM64 to the checked definitions alongside CONFIG_X86_64 to
enable the use of rbit/clz instructions on full 64-bit quantities.

When using zram, we frequently encounter long runs of zero bytes.
This adds a special case which identifies runs of zeros and encodes
them using run-length encoding.
This is faster for both compression and decompresion. For
high-entropy data which doesn't hit this case, impact is minimal.

Is there a semantic divergence between x86 instruction "LOCK cmpxchg" and the
macro cmpxchg defined in linux kernel? The former guarantee full barrier in any
case, and the latter only imply barrier in case of success?
So, we use
smp_mb__before_atomic()

Since commit 0aa802a79469 ("perf stat: Get rid of extra clock display
function"), the cpu and task clock unit has been changed from
nanosecond value to millisecond value. This introduces confusion for
CPU run time statistics, we can see in below flow the clock value is
scaled from nanosecond value
