Subject: [PATCH 4.19 09/13] staging: m57621-mmc: delete driver from the tree.

---

From: Greg Kroah-Hartman <[email protected]>

[ Upstream commit 441bf7332d55c4d34afae9ffc3bbec621093f4d1 ]

The license text in this driver is "interesting" and not really obvious
that it is supposed to be able to be distributed in the kernel source
tree. Yes, the MODULE_LICENSE() text says GPL, so it's probably ok, but
to be safe, I am deleting this driver. I will be glad to add it back if
the license is properly sorted out, but for now, this isn't worth the
potential risk, I should have never taken it in the first place.

Subject: [PATCH 4.19 07/13] riscv,entry: fix misaligned base for excp_vect_table

---

From: Zihao Yu <[email protected]>

[ Upstream commit ac8d0b901f0033b783156ab2dc1a0e73ec42409b ]

In RV64, the size of each entry in excp_vect_table is 8 bytes. If the
base of the table is not 8-byte aligned, loading an entry in the table
will raise a misaligned exception. Although such exception will be
handled by opensbi/bbl, this still causes performance degradation.

We should not be advertising EEE for modes that we do not support,
correct that oversight by looking at the PHY device supported linkmodes.
