19b02cf4ed arm64_cpu_capabilities: flatten struct 
The midr_* part of the struct was never used, and confuses older gcc
with partially uninitialized assignments that were not correct.
Just flatten the struct

abc0a7bdac mcs_rwlock: remove aligned(64) attribute if ENABLE_UBSAN 
The attribute would impose 64-bytes alignment that we do not
respect later because the whole structures (e.g. process/thread)
are allocated at 32bytes boundaries with kmalloc

These are however justified for performance reason as we do not want
them on same page cache line, so just accept slower performance for
UBSAN only

4d215de641 Separate mmap area from program loading (relocation) area 
We need to separate the two because the heap of a PIE is created in
the area to which it is mapped.

Related commits:

b1309a5d: PIE is mapped at map_end instead of at
          user_start
c4219655: Interpreter is mapped to map_start to make a
          system call that dereferences a NULL pointer fail

were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats
