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.

Select MEM_ACCESS_ALWAYS_ON on x86 to mark that MEM_ACCESS is not
configurable on x86. Avoid selecting it on ARM.
Rename HAS_MEM_ACCESS to MEM_ACCESS everywhere. Add a prompt and a
description to MEM_ACCESS in xen/common/Kconfig.
The result is that the user-visible option is MEM_ACCESS, and it is
configurable only on ARM (disabled by default). At the moment the
arch-specific mem_access code remains enabled on ARM, even with
MEM_ACCESS=y.
The purpose is to reduce code size. The option doesn't depend on EXPERT
because it would be nice to ecurity-support configurations without
MEM_ACCESS and a non-expert should be able to disable it.

The objcopy step of the shim build is also removed in this patch:
since the shim is booted in PVH mode there's no need for the resulting

Commit 149c6b unmasked an issue long present in Xen: the control/event
block addresses provided in the ACPI FADT table where hardcoded to the
V1 version. This was papered over because hvmloader would also always
set HVM_PARAM_ACPI_IOPORTS_LOCATION to 1 regardless of the BIOS
version.
The most notable issue caused by the above bug was that the QEMU
traditional GPE0 block was out of sync: the address provided in the
FADT didn't match the address QEMU was using.
Note that PM1a and TMR worked fine because the V1 address was
hardcoded in the FADT and HVM_PARAM_ACPI_IOPORTS_LOCATION was
unconditionally set to 1 by hvmloader.
Fix this by passing the address of the control/event blocks to
acpi_build_tables, so the values can be properly set in the FADT table
provided to the guest.

a. two rmrr exist, small gap between them
b. pci_mem_start and mem_resource.base is below the first rmrr.base
c. find_next_rmrr(pci_mem_start) will find the first rmrr
d. After aligning mem_resource.base to bar size,
first_rmrr.end < new_base < second_rmrr.base and
new_base + bar_sz > second_rmrr.base.
So the new bar will overlap with the second rmrr and doesn't overlap

But the next_rmrr point to the first rmrr, then check_overlap() couldn't
find the overlap. Finally assign a wrong address to bar.

In order to make uninstall correctly remove the files it is best
the process should be done recursively by mirroring each "install"
target with an "uninstall" who removes the installed files.
An exception to this rule is uninstalling the files produced by
"qemu-xen-dir-remote" and "qemu-xen-traditional-dir", which are external
to the project. These projects do not implement an "uninstall" target so
