Subject: [PATCH 04/10] x86/Kconfig: drop X86_32_NON_STANDARD
Date: Mon, 28 Feb 2022 22:28:20 +0100 [thread overview]
Message-ID: <20220228212826.27080-5-mat.jonczyk@o2.pl> (raw)
In-Reply-To: <20220228212826.27080-1-mat.jonczyk@o2.pl>
This patch drops the "Support non-standard 32-bit SMP architectures"
configuration option. Currently, the only such an architecture is
STA2X11, so this option is useless. STA2X11 could now be selected
independently.
The dependency of X86_BIGSMP on X86_32_NON_STANDARD was dropped in
2009, in
commit 26f7ef14a76b ("x86: don't treat bigsmp as non-standard")
but the help text for X86_32_NON_STANDARD was not updated since.
CONFIG_X86_32_NON_STANDARD was used only in arch/x86/Kconfig, so it
could be dropped easily.
X86_32_NON_STANDARD depended on SMP, so
(!SMP && !X86_32_NON_STANDARD) == !SMP
and
(SMP || X86_32_NON_STANDARD) == SMP
