Commit58ea30f514"Clean up header guards that don't match their file name" messed up contrib/elf2dmp/qemu_elf.h and tests/migration/migration-test.h. It missed target/cris/opcode-cris.h and tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h due to the scripts/clean-header-guards.pl bug fixed in the previous commit. Commita8b991b52d"Clean up ill-advised or unusual header guards" missed include/hw/xen/io/ring.h for the same reason. Commit3979fca4b6"disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h" neglected to update the guard symbol for the rename. Commita331c6d774"semihosting: implement a semihosting console" created include/hw/semihosting/console.h with an ill-advised guard symbol. Clean them up.

Expose the address(es) of the ACPI RSD PTR table(s) and the SMBIOS entry
|
|
point(s) in a MB-aligned structure to the hypervisor.
|
|
|
|
The hypervisor locates the MB-aligned structure based on the signature GUID
|
|
that is at offset 0 in the structure. Once the RSD PTR and SMBIOS anchor
|
|
address(es) are retrieved, the hypervisor may perform various ACPI and SMBIOS
|
|
checks.
|
|
|
|
This feature is a development aid, for supporting ACPI and SMBIOS table unit
|
|
tests in hypervisors. Do not enable in production builds.
