In linux kernel since version 2.6.30 (release Date: 2009-06-09)
This option enables the workaround for the 460075 Cortex-A8 (r2p0)
erratum. Any asynchronous access to the L2 cache may encounter a
situation in which recent store transactions to the L2 cache are lost
and overwritten with stale memory contents from external memory. The
workaround disables the write-allocate mode for the L2 cache via the
ACTLR register. Note that setting specific bits in the ACTLR register
may not be available in non-secure mode.
