      x86/efi: earlyprintk=efi,keep fix · 34f51147
      Dave Young authored
      earlyprintk=efi,keep will cause kernel hangs while freeing initmem like
      below:
      
        VFS: Mounted root (ext4 filesystem) readonly on device 254:2.
        devtmpfs: mounted
        Freeing unused kernel memory: 880K (ffffffff817d4000 - ffffffff818b0000)
      
      It is caused by efi earlyprintk use __init function which will be freed
      later.  Such as early_efi_write is marked as __init, also it will use
      early_ioremap which is init function as well.
      
      To fix this issue, I added early initcall early_efi_map_fb which maps
      the whole efi fb for later use. OTOH, adding a wrapper function
      early_efi_map which calls early_ioremap before ioremap is available.
      
      With this patch applied efi boot ok with earlyprintk=efi,keep console=efi
