X-Debbugs-Cc: geoff@infradead.org, Riku Voipio <riku.voipio@linaro.org>
Source: linux
Severity: normal
Tags: patch buster
Attached patches enable kernel features for newer ARM64 servers.
o Change CONFIG_ACPI_NFIT=y to CONFIG_ACPI_NFIT=m.
o Enable CONFIG_SCHED_SMT for hyperthreading processors.
o Enable CONFIG_ARM64_LSE_ATOMICS for v8.1 processors.
o Enable a number of ACPI options likely to be available on servers.
o CONFIG_ACPI_APEI selects PSTORE, so remove the arm64 specific setting.

Subject: [PATCH 1/4] [arm64] Use default of CONFIG_ACPI_NFIT=m
Commit ed497f3cb706d0e0f63844b064d9ebbf6f33b052 (Add server and 96boards options)
added an arm64 specific CONFIG_ACPI_NFIT=y, overriding the default of =m, but the
commit message mentions nothing about why this was done.
Remove the arm64 specific setting and use the default of module build.
