Hi,
so with my current distro (openSUSE TW):
$ zgrep NODES_SHIFT /proc/config.gz
CONFIG_NODES_SHIFT=10
This:
static u8 amd_ucode_patch[MAX_NUMNODES][PATCH_MAX_SIZE];
is now 32M instead of 12M. That is a complete waste on my _one_ node
system. Can we make amd_ucode_patch dynamic first, depending on
num_online_nodes()?

I have a small set which gets rid of all those arrays - I just need to
finish it.

Remove stable@.
This below seems to work here on a couple of machines.
Can you run it too pls to confirm?
Thx.

Subject: [PATCH] x86/microcode/AMD: Rip out static buffers
Load straight from the containers (initrd or builtin, for example).
There's no need to cache the patch per node.
This even simplifies the code a bit with the opportunity for more
cleanups later.
