load_microcode_amd() (and the helper it is using) should not have an
cpu parameter. The microcode loading does not depend on the CPU wrt the
patches loaded since they will end up in a global list for all CPUs
anyway.
The change from cpu to x86family in load_microcode_amd()
now allows to drop the code messing with cpu_data(cpu) from
collect_cpu_info_amd_early(), which is wrong anyway because at that
point the per-cpu cpu_info is not yet setup (These values would later be
overwritten by smp_store_boot_cpu_info() / smp_store_cpu_info()).
Fold the rest of collect_cpu_info_amd_early() into load_ucode_amd_ap(),
because its only used at one place and without the cpuinfo_x86 accesses
it was not much left.

cpu_has_amd_erratum() is buggy, because it uses the per-cpu cpu_info
before it is filled by smp_store_boot_cpu_info() / smp_store_cpu_info().
If early microcode loading is enabled its collect_cpu_info_amd_early()
will fill ->x86 and so the fallback to boot_cpu_data is not used. But
->x86_vendor was not filled and is still X86_VENDOR_INTEL resulting in
no errata fixes getting applied and my system hangs on boot.
Using cpu_info in cpu_has_amd_erratum() is wrong anyway: its only
caller init_amd() will have a struct cpuinfo_x86 as parameter and the
set_cpu_bug() that is controlled by cpu_has_amd_erratum() also only uses
that struct.
So pass the struct cpuinfo_x86 from init_amd() to cpu_has_amd_erratum()
and the broken fallback can be dropped.

Some PCI drivers may need to adjust the pci_bus structure after it has
been allocated by the Linux PCI core. The PCI core allows
architectures to implement the pcibios_add_bus() and
pcibios_remove_bus() for this purpose. This commit therefore extends
the hw_pci and pci_sys_data structures of the ARM PCI core to allow
PCI drivers to register ->add_bus() and ->remove_bus() in hw_pci,
which will get called when a bus is added or removed from the system.
This will be used for example by the Marvell PCIe driver to connect a
particular PCI bus with its corresponding MSI chip to handle Message
Signaled Interrupts.

The new struct msi_chip is used to associated an MSI controller with a
PCI bus. It is automatically handed down from the root to its children
during bus enumeration.
This patch provides default (weak) implementations for the architecture-
specific MSI functions (arch_setup_msi_irq(), arch_teardown_msi_irq()
and arch_msi_check_device()) which check if a PCI device's bus has an
attached MSI chip and forward the call appropriately.

Until now, the MSI architecture-specific functions could be overloaded
using a fairly complex set of #define and compile-time
conditionals. In order to prepare for the introduction of the msi_chip
infrastructure, it is desirable to switch all those functions to use
the 'weak' mechanism. This commit converts all the architectures that
were overidding those MSI functions to use the new strategy.
Note that we keep two separate, non-weak, functions
default_teardown_msi_irqs() and default_restore_msi_irqs() for the
default behavior of the arch_teardown_msi_irqs() and
arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI
code.

On newer models, support has been included for upto 4 DCT's, however,
only DCT0 and DCT3 are currently configured (cf BKDG Section 2.10).
Also, the routing DRAM Requests algorithm is different for F15h M30h.
Thus it is cleaner to use a brand new function rather than adding quirks
to the more generic f1x_match_to_this_node(). Refer to "2.10.5 DRAM
Routing Requests" in the BKDG for further info.
Tested on Fam15h M30h with ECC turned on using mce_amd_inj facility and
verified to be functionally correct.
While at it, verify if erratum workarounds for E505 and E637 still hold.
From email conversations within AMD, the current status of the errata

The motivation of adding __ext4_journal_stop() into

improve error reporting. So replace __ext4_journal_stop() with
ext4_journal_abort_handle() which was there before that commit and add

F15h, models 0x30 and later don't have a GART. Note that. Also check
CPUID leaf 0x80000006 for L3 prescence because there are models which
don't sport an L3 cache.

tree when doing the swap.
