    pvgrub: use printk() instead of grub_printf()

    Especially some error messages suffer from that, e.g. %lx won't work.
    Switch to use printk() for error messages instead.

    When trying to boot a kernel with the p2m list not mapped by the
    initial kernel mapping it can happen that pvgrub is failing as it is
    keeping some page tables mapped.
    
    Unmap the additional page tables created for the special p2m mapping
    will avoid this failure.

    livepatch: arm[32,64],x86: NOP test-case
    
    The test-case is quite simple - we NOP the 'xen_minor_version'.
    The amount of NOPs depends on the architecture.
    
    On x86 the function is 11 bytes long:
    
       55                      push   %rbp      <- NOP
       48 89 e5                mov    %rsp,%rbp <- NOP
       b8 04 00 00 00          mov    $0x4,%eax <- NOP
       5d                      pop    %rbp      <- NOP
       c3                      retq
    
    We can NOP everything but the last instruction (so 10 bytes).
    
    On ARM64 its 8 bytes:
    
      52800100    mov w0, #0x8         <- NOP
      d65f03c0    ret
    
    We can NOP the first instruction.
    
    While on ARM32 there are 24 bytes:
    
      e52db004        push    {fp}       <- NOP
      e28db000        add     fp, sp, #0 <- NOP
      e3a00008        mov     r0, #8     <- NOP
      e24bd000        sub     sp, fp, #0 <- NOP
      e49db004        pop     {fp}       <- NOP
      e12fff1e        bx      lr
    
    And we can NOP instructions 1 through 5.
    
    Granted this code may be different per compiler!
    
    Hence if anybody does run this test-case - they should
    verify that the assumptions made here are correct.

    livepatch: Initial ARM32 support.
    
    The patch piggybacks on: livepatch: Initial ARM64 support, which
    brings up all of the necessary livepatch infrastructure pieces in.
    
    This patch adds three major pieces:
    
     1) ELF relocations. ARM32 uses SHT_REL instead of SHT_RELA which
        means the adddendum had to be extracted from within the
        instruction. Which required parsing BL/BLX, B/BL<cond>,
        MOVT, and MOVW instructions.
    
        The code was written from scratch using the ARM ELF manual
        (and the ARM Architecture Reference Manual)
    
     2) Inserting an trampoline. We use the B (branch to address)
        which uses an offset that is based on the PC value: PC + imm32.
        Because we insert the branch at the start of the old function
        we have to account for the instruction already being fetched
        and subtract -8 from the delta (new_addr - old_addr). See
        ARM DDI 0406C.c, see A2.3 (pg 45) and A8.8.18 pg (pg 334,335)
    
     3) Allows the test-cases to be built under ARM 32.
        The "livepatch: tests: Make them compile under ARM64"
        put in the right infrastructure for it and we piggyback on it.

    livepatch: tests: Make them compile under ARM64
    
    We need to two things:
    1) Wrap the platform-specific objcopy parameters in defines
       The input and output parameters for $(OBJCOPY) are different
       based on the platforms. As such provide them in the
       OBJCOPY_MAGIC define and use that.
    
    2) The alternative is a bit different (exists only under ARM64
       and x86), while and there are no exceptions under ARM at all.
       We use the LIVEPATCH_FEATURE CPU id feature for ARM similar to
       how it is done on x86.
    
    We are not yet attempting to build them under ARM32 so
    that is still ifdefed out.

    livepatch/arm/x86: Check payload for for unwelcomed symbols.
    
    Certain platforms, such as ARM [32|64] add extra mapping symbols
    such as $x (for ARM64 instructions), or more interesting to
    this patch: $t (for Thumb instructions). These symbols are supposed
    to help the final linker to make any adjustments (such as
    add an veneer). But more importantly - we do not compile Xen
    with any Thumb instructions (which are variable length) - and
    if we find these mapping symbols we should disallow such payload.

    Those symbols are used to help final linkers to replace insn.
    The ARM ELF specification mandates that they are present
    to denote the start of certain CPU features. There are two
    variants of it - short and long format.
    
    Either way - we can ignore these symbols.

    livepatch: ARM/x86: Check displacement of old_addr and new_addr
    
    If the distance is too big we are in trouble - as our relocation
    distance can surely be clipped, or still have a valid width - but
    cause an overflow of distance.
    
    On various architectures the maximum displacement for a unconditional
    branch/jump varies. ARM32 is +/- 32MB, ARM64 is +/- 128MB while x86
    for 32-bit relocations is +/- 2G.
    
    Note: On x86 we could use the 64-bit jmpq instruction which
    would provide much bigger displacement to do a jump, but we would
    still have issues with the new function not being able to reach
    any of the old functions (as all the relocations would assume 32-bit
    displacement). And "furthermore would require an register or
    memory location to load/store the address to." (From Jan).
    
    On ARM the conditional branch supports even a smaller displacement
    but fortunately we are not using that.

    livepatch: Initial ARM64 support.
    
    As compared to x86 the va of the hypervisor .text
    is locked down - we cannot modify the running pagetables
    to have the .ro flag unset. We borrow the same idea that
    alternative patching has - which is to vmap the entire
    .text region and use the alternative virtual address
    for patching.
    
    Since we are doing vmap we may fail, hence the
    arch_livepatch_quiesce was changed (see "x86,arm:
    Change arch_livepatch_quiesce() declaration") to return
    an error value which will be bubbled in payload->rc and
    provided to the user (along with messages in the ring buffer).
    
    The livepatch virtual address space (where the new functions
    are) needs to be close to the hypervisor virtual address
    so that the trampoline can reach it. As such we re-use
    the BOOT_RELOC_VIRT_START which is not used after bootup
    (alternatively we can also use the space after the _end to
    FIXMAP_ADDR(0), but that may be too small).
    
    The ELF relocation engine at the start was coded from
    the "ELF for the ARM 64-bit Architecture (AArch64)"
    
(http://infocenter.arm.com/help/topic/com.arm.doc.ihi0056b/IHI0056B_aaelf64.pdf)
    but after a while of trying to write the correct bit shifting
    and masking from scratch I ended up borrowing from Linux, the
    'reloc_insn_imm' (Linux v4.7 arch/arm64/kernel/module.c function.
    See 257cb251925f854da435cbf79b140984413871ac "arm64: Loadable modules")
    
    And while at it - we also utilize code from Linux to construct
    the right branch instruction (see "arm64/insn: introduce
    aarch64_insn_gen_{nop|branch_imm}() helper functions").
    
    In the livepatch payload loading code we tweak the #ifdef to
    only exclude ARM_32. The exceptions are not part of ARM 32/64 hence
    they are still behind the #ifdef.
    
    We also expand the MAINTAINERS file to include the arm64 and arm32
    platform specific livepatch file.
