Subject: [PATCH 3/3] powerpc: Update NUMA Kconfig description & help text
Date: Tue, 24 Nov 2020 23:05:47 +1100	[thread overview]
Message-ID: <20201124120547.1940635-3-mpe@ellerman.id.au> (raw)
In-Reply-To: <20201124120547.1940635-1-mpe@ellerman.id.au>

Update the NUMA Kconfig description to match other architectures, and
add some help text. Shamelessly borrowed from x86/arm64.
