zRam as swap is useful for small memory device. However, swap means
those pages on zram are mostly cold pages due to VM's LRU algorithm.
Especially, once init data for application are touched for launching,
they tend to be not accessed any more and finally swapped out.
zRAM can store such cold page
ZRAM_ACCESS is meant to lock a slot of zram so correct the name.

It's common practice to store MAC addresses for network interfaces into
nvmem devices. However the code to actually do this in the kernel lacks,
so this patch adds of_get_nvmem_mac_address() for drivers to obtain the
address from an nvmem cell provider.
This is particulary useful on devices where

Current logic iterates over CPUID Fn801d leafs (Cache Properties)

However, this information is already available in the cpu_llc_id.
Therefore, make use of it instead.

Last-Level-Cache ID can be calculated from the number of threads sharing
the cache, which is available from CPUID Fn0x801D (Cache Properties).
This is used to left-shift the APIC ID to derive LLC ID.
Therefore, default to this method unless the APIC ID enumeration does not
follow the scheme.
First, clean up last-level-cache parameters so that it could not
require ifdef CONFIG_SMP. Then, consolidate cache-info-related
code for x86 into arch/x86/kernel/cpu/cacheinfo.c.
Finally, for AMD, introduce new logic to derive LLC ID from APIC ID.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
(kernel Oops) or a security flaw (overwriting memory beyond the
