Subject: [PATCH 01/12] mips: Make sure kernel .bss exists in boot mem pool
Date: Wed, 24 Apr 2019 01:47:37 +0300 [thread overview]
Message-ID: <20190423224748.3765-2-fancer.lancer@gmail.com> (raw)
In-Reply-To: <20190423224748.3765-1-fancer.lancer@gmail.com>
Current MIPS platform code makes sure the kernel text, data and init
sections are added to the boot memory map pool right after the
arch-specific memory setup method has been executed. But for some reason
the MIPS platform code skipped the kernel .bss section, which definitely
should be in the boot mem pool as well in any case. Lets fix this just be
adding the space between __bss_start and __bss_stop.
