Subject: [PATCH 2/2] ARM: defconfig: turn off CONFIG_EXPERT
Date: Mon, 12 Jan 2026 16:32:55 +0100 [thread overview]
Message-ID: <20260112153255.795553-2-arnd@kernel.org> (raw)
In-Reply-To: <20260112153255.795553-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Since multi_v7_defconfig is meant to be the generic defconfig, many
users are not going to be experts and it is counterintuitive to have
CONFIG_EXPERT enabled.
This change has a couple of side-effects:
- CONFIG_NAMESPACES is enabled by default. This adds about 0.2% of
.text, but is already enabled in many board specific configs, and
apparently a requirement for systemd, so this seems like a useful
change.
- CONFIG_DEBUG_MEMORY_INIT is enabled now, adding a tiny bit
of code in the inittext section
- CONFIG_RFKILL, CONFIG_MEDIA_SUPPORT_FILTER and various CONFIG_HID
driver defaults change, so these have to be listed explicitly to
maintain the previous behavior
- CONFIG_SERIAL_SH_SCI_NR_UARTS=20 changes to the default value
of 18, which I understand to be sufficient for any buard, even
if all UARTS are enabled at the same time
