commit 09b3907f93fe023ebca809c9f706f3d022801dce
Author: Roger Pau Monné <roger.pau@citrix.com>
Date:   Mon Sep 3 17:54:12 2018 +0200

    The hvmloader binary generated when using LLVM LD doesn't work
    properly and seems to get stuck while trying to generate and load the
    ACPI tables. This is caused by the layout of the binary when linked
    with LLVM LD.
    
    LLVM LD has a different default linker script that GNU LD, and the
    resulting hvmloader binary is slightly different:
    
    LLVM LD:
    Program Headers:
      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      PHDR           0x000034 0x000ff034 0x000ff034 0x00060 0x00060 R   0x4
      LOAD           0x000000 0x000ff000 0x000ff000 0x38000 0x38000 RWE 0x1000
      GNU_STACK      0x000000 0x00000000 0x00000000 0x00000 0x00000 RW  0
    
    GNU LD:
    Program Headers:
      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      LOAD           0x000080 0x00100000 0x00100000 0x36308 0x3fd74 RWE 0x10
      GNU_STACK      0x000000 0x00000000 0x00000000 0x00000 0x00000 RW  0x4
    
    Note that in the LLVM LD case (as with GNU LD) the .text section does
    indeed have the address set to 0x100000 as requested on the command
    line:
    
    [ 1] .text             PROGBITS        00100000 001000 00dd10 00  AX  0   0 16
    
    There's however the PHDR which is not present when using GNU LD.
    
    Fix this by using a very simple linker script that generates the same
    binary regardless of whether LLVM or GNU LD is used. By using a linker
    script the usage of -Ttext can also be avoided by placing the desired
    .text load address directly in the linker script.

    x86/boot: silence MADT table entry logging
    
    Logging disabled LAPIC / x2APIC entries with invalid local APIC IDs
    (ones having "broadcast" meaning when used) isn't very useful, and can
    be quite noisy on larger systems. Suppress their logging unless
    opt_cpu_info is true.

    x86: assorted array_index_nospec() insertions
    
    Don't chance having Spectre v1 (including BCBS) gadgets. In some of the
    cases the insertions are more of precautionary nature rather than there
    provably being a gadget, but I think we should err on the safe (secure)
    side here.
