Subject: ARM: disable __minix_init for now
X-Git-Tag: v3.2.1~66
X-Git-Url: http://zhaoyanbai.com/repos/%7B%24global.css%7D?a=commitdiff_plain;h=fe45ee7ed0a946bf2bd10276de33f7b2bef5f302;p=minix.git

ARM: disable __minix_init for now

On ARM we can't yet globally map pages into every process. So now that
we correctly receive the pointer to the globally mapped kern_info
struct, we have to ignore it on ARM because attempting to dereference
the pointer yields a segfault.
