Subject: [PATCH] MIPS: fix mapstart when using initrd
Content-Type: text/plain
When initrd is present in the PFN right after the _end, bootmem
bitmap(mapstart) overwrites it. So check for initrd_end in
mapstart calculation.

This is seen after the commit
"mips: fix start of free memory when using initrd"
in git://git.linux-mips.org/pub/scm/ralf/upstream-sfr.git branch
Tested the image on MIPS platform creating the above
said scenario and initrd was corrupted.
And it gloriously breaks the build if CONFIG_BLK_DEV_INITRD is disabled.
Now most configurations will fail with something like:
[...]
LD vmlinux
arch/mips/built-in.o: In function `setup_arch':
(.init.text+0xff8): undefined reference to `initrd_end'
arch/mips/built-in.o: In function `setup_arch':
(.init.text+0xffc): undefined reference to `initrd_end'
make[2]: *** [vmlinux] Error 1
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

Hi Ralf,
