    kexec: use common function for kimage_normal_alloc() and kimage_crash_alloc() · 255aedd9
    Vivek Goyal authored
    kimage_normal_alloc() and kimage_crash_alloc() are doing lot of similar
    things and differ only little.  So instead of having two separate
    functions create a common function kimage_alloc_init() and pass it the
    "flags" argument which tells whether it is normal kexec or kexec_on_panic.
     And this function should be able to deal with both the cases.
    
    This consolidation also helps later where we can use a common function
    kimage_file_alloc_init() to handle normal and crash cases for new file
    based kexec syscall.
