[PATCH v3] IOMMU: keep disabled until iommu_setup() is called
...of
disable_IO_APIC() / __stop_this_cpu().
This patch fixes this by keeping the iommu disabled until iommu_setup()
is entered.
Originally-by: Ronny Hegewald <ronny.hegewald@online.de>
In order for iommu_enable to be off initially, iommu_supports_eim()
must not depend on it anymore, nor must acpi_parse_dmar(). The former
in turn requires that iommu_intremap gets uncoupled from iommu_enabled
(in particular, failure during IOMMU setup should no longer result in
iommu_intremap getting cleared by generic code; IOMMU specific code
can still do so provided in can live with the consequences).

x86: fix tboot after c/s 23013:65d26504e843 (ACPI cleanup)
TXT code calls acpi_parse_dmar() with a transient copy of the DMAR
table, and hence storing the pointer for later reference was wrong.
Obtain the pointer in acpi_dmar_init() instead.

Workaround for the corrupted Intel X48 DMAR table
hi,
I am trying the Xen unstable on X48 chipset these days but it failed due to
an corrupted RMRR table in the ACPI. The following is the acpi dump of DMAR.
