Restore dropped patches in the non-TLS branch of memory.c ( #2004 )
...
* Restore dropped patches in the non-TLS branch of memory.c
As discovered in #2002 , the reintroduction of the "original" non-TLS version of memory.c as an alternate branch had inadvertently used ba1f91fa8002e2#1450 , #1468 , #1501 , #1504 and #1520 .

sgemm/dgemm: add a way for an arch kernel to specify prefered sizes
...
The current gemm threading code can make very unfortunate choices, for
example on my 10 core system a 1024x1024x1024 matrix multiply ends up
chunking into blocks of 102... which is not a vector friendly size
and performance ends up horrible.
this patch adds a helper define where an architecture can specify
a preference for size multiples.
This is different from existing defines that are minimum sizes and such.
The performance increase with this patch for the 1024x1024x1024 sgemm
is 2.3x (!!)

ARM64: Enable DYNAMIC_ARCH
...
Enable DYNAMIC_ARCH feature on ARM64. This patch uses the cpuid
feature in linux kernel to detect the core type at runtime
(https://www.kernel.org/doc/Documentation/arm64/cpu-feature-registers.txt ).
If this feature is missing in kernel, then the user should use the
OPENBLAS_CORETYPE env variable to select the desired core type.

Fix #1705 where we incorrectly calculate page locations.

Since we now use an allocation size that isn't a multiple of PAGESIZE, finding
the pages for run_bench wasn't terminating properly. Now we detect if we've
found enough pages for the allocation and terminate the loop.
