49ad084503 Few improvements related to CPU cache line size and padding:
Bug #79636: CACHE_LINE_SIZE should be 128 on AArch64
Bug #79637: Hard-coded cache line size
Bug #79638: Reconcile CACHE_LINE_SIZE with CPU_LEVEL1_DCACHE_LINESIZE
Bug #79652: Suspicious padding in srv_conc_t

- changed CPU_LEVEL1_DCACHE_LINESIZE to default to 128 bytes on POWER
  and AArch64 architectures in cases when no value could be detected
  by CMake using getconf

- changed CACHE_LINE_SIZE definition in ut0counter.h to be an alias of
  CPU_LEVEL1_DCACHE_LINESIZE

- changed a number of hard-coded 64-byte cache line size values in the
  InnoDB code

- fixed insufficient padding for srv_conc members in srv0conc.cc

Ported to Mariadb by Daniel Black <daniel.black@au.ibm.com>
Added s390 cache size of 256 at same time.

ffa8c4cfcc Percona-Server-5.6.14-rel62.0 merge
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module

update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply

small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream

fix XtraDB to compile on Windows (both as a static and a dynamic plugin)

disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)


storage/innobase/handler/ha_innodb.cc:
  revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
  correct the version to match what it was merged from
