  • 342cd340f   xen/efi: Directly include needed headers ... Browse Code »

    I discovered that some needed stuff is defined/declared in headers
    which are not included directly. Currently it works but if somebody
    remove required headers from currently included headers then build
    will break. So, just in case directly include all needed headers.

  • c7341d6a6   arch/x86/xen: Silence compiler warnings ... Browse Code »

    Compiler complains in the following way when x86 32-bit kernel
    with Xen support is build:

    CC arch/x86/xen/enlighten.o
    arch/x86/xen/enlighten.c: In function ‘xen_start_kernel’:
    arch/x86/xen/enlighten.c:1726:3: warning: right shift count >= width of type [enabled by default]

    Such line contains following EFI initialization code:

    boot_params.efi_info.efi_systab_hi = (__u32)(__pa(efi_systab_xen) >> 32);

    There is no issue if x86 64-bit kernel is build. However, 32-bit case
    generate warning (even if that code will not be executed because Xen
    does not work on 32-bit EFI platforms) due to __pa() returning unsigned long
    type which has 32-bits width. So move whole EFI initialization stuff
    to separate function and build it conditionally to avoid above mentioned
    warning on x86 32-bit architecture.
