Subject: [PATCH 17/50] x86/boot/e820: Rename default_machine_specific_memory_setup() to e820__memory_setup_default()
Date: Sat, 28 Jan 2017 23:11:38 +0100 [thread overview]
Message-ID: <1485641531-22124-18-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1485641531-22124-1-git-send-email-mingo@kernel.org>
The default_machine_specific_memory_setup() is a mouthful and despite the
many words it doesn't actually tell us clearly what it does.
The function is the x86 legacy memory layout setup code, based on
E820-formatted memory layout information passed by the bootloader
via the boot_params.
Rename it to e820__memory_setup_default() to better signal its purpose.
Also rename the related higher level function to be consistent with
this new naming:
setup_memory_map() => e820__memory_setup()
No change in functionality.
