    kexec: allocate the kexec control page with KEXEC_CONTROL_MEMORY_GFP · 7e01b5ac
    Martin Schwidefsky 提交于
    Introduce KEXEC_CONTROL_MEMORY_GFP to allow the architecture code
    to override the gfp flags of the allocation for the kexec control
    page. The loop in kimage_alloc_normal_control_pages allocates pages
    with GFP_KERNEL until a page is found that happens to have an
    address smaller than the KEXEC_CONTROL_MEMORY_LIMIT. On systems
    with a large memory size but a small KEXEC_CONTROL_MEMORY_LIMIT
    the loop will keep allocating memory until the oom killer steps in.
