Subject: [PATCH] radeonsi: Temporary patch to fix corruption with persitent
 buffers

Until further debugging is done set kernel_flushes_hdp_before_ib to
false so persistent buffers are allocated from GTT memory.  I have
an open issue for this in mesa that perhaps this should become a
runtime DRI option that can be enabled.

Subject: [PATCH] radeonsi: On Aarch64 force persistent buffers to GTT

This fixes a glamore corruption issue on the HoneyComb and by
internet reports should also fix problems seen on Huaweii
Kunpeng hardware.

The root cause of the corruption needs to be worked out, but

Subject: [PATCH] Aarch64: Make memcpy more compatible with device memory

For normal non-cacheable memory ACE supports 4x128 bit r/w WRAP
transfers or 1x128 bit r/w INCR transfers.  By re-ordering the
stp's in memcpy / memmove we can accomodate this better without
impacting the existing code.
