Subject: MIPS: Make init_vdso a subsys_initcall.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1ed845375b1f2938acc4496a186e180892b00c71;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

MIPS: Make init_vdso a subsys_initcall.

Quoting from Jiri Slaby's patch of a similar nature for x86:

    When initrd is in use and a driver does request_module() in its
    module_init (i.e. __initcall or device_initcall), a modprobe
    process is created with VDSO mapping. But VDSO is inited even in
    __initcall, i.e. on the same level (at the same time), so it may
    not be inited yet (link order matters).

Move init_vdso up to subsys_initcall to avoid the issue.
