[BUGFIX PATCH 0/1] bootconfig: Fix wrong initramfs/initrd error with bootconfig

[Masami Hiramatsu]

Hello,

I found that the bootconfig breaks initramfs unpacking.
I saw an error message as following if I apply a bootconfig
to initramfs image.

[    0.883882] Unpacking initramfs...
[    2.696429] Initramfs unpacking failed: invalid magic at start of compressed archive

Without CONFIG_BLK_DEV_RAM, it has no failback method,
so boot up with unpacked initramfs normally. But with
CONFIG_BLK_DEV_RAM=y, the kernel tries to failback to
initrd and failes to mount rootfs.

To fix this issue, I took a way to shrink the initrd_end
so that the kernel can ignore the bootconfig data.

Any thought?

Thank you,
