Hello guys !

When enter page_alloc slowpath, we wakeup kswapd on every pgdat
according to the zonelist and high_zoneidx. However, this doesn't
take nodemask into account, and could prematurely wakeup kswapd on
some unintended nodes.
This patch uses for_each_zone_zonelist_nodemask() instead of

This adds missing locks in iommu_take_ownership()/

This marks all pages busy in iommu_table::it_map in order to catch
errors if there is an attempt to use this table while ownership over it
is taken.
This only clears TCE content if there is no page marked busy in it_map
This defines and implements VFIO IOMMU API which lets the userspace
create and remove DMA windows.

This adds VFIO_IOMMU_SPAPR_TCE_CREATE and VFIO_IOMMU_SPAPR_TCE_REMOVE

Modern IBM POWERPC systems support multiple IOMMU tables per PE

the iommu_table struct. This moves tce_build/tce_free/tce_get/tce_flush

This adds an extra @ops parameter to iommu_init_table() to make sure

SPAPR defines an interface to create additional DMA windows dynamically.
"Dynamically" means that the window is not allocated before the guest
even started, the guest can request it later. In practice, existing linux
guests check for the capability and if it is there, they create and map
a DMA wind
Normally a bitmap from the iommu_table is used to track what TCE entry
is in use. Since we are going to use iommu_table without its locks and
do xchg() instead, it becomes essential not to put bits which are not
implied in the direction flag.

The previous patch introduced iommu_table_ops::exchange() callback
which effectively disabled VFIO on pseries. This implements exchange()
for pseries/lpar so VFIO can work in nested guests.
Since exchaange() callback returns an old TCE, it has to call H_GET_TCE
for every TCE being put to the table
At the moment the iommu_table struct has a set_bypass() which enables/
disables DMA bypass on IODA2 PHB. This is exposed to POWERPC IOMMU code
which calls this callback when external IOMMU users such as VFIO are
about to get over a PHB.
Since the set_bypass() is not really an iommu_table function
At the moment writing new TCE value to the IOMMU table fails with EBUSY

Since commit 2321f33790a6c5b80322d907a92d5739e7521a13, r10 is not used anymore
after FixupDAR. There is therefore no need to set it up with the value of DAR.

Branching takes two cycles on MPC8xx. Lets duplicate the two instructions
and avoid the branching.

By XORing the upper part of the instruction code, we get a value that can
directly be verified with the second test and we can remove the first test.

This patch hiddes that SPR address needed for CPU6 ERRATA handling in the macro.
Then we don't have to worry about this address directly in the code.

Use M_TW instead of M_TWB for storing Level 1 table address as M_TWB requires
4k aligned tables, which is only the case with 4k pages.
Consequently, we have to calculate the level 1 table index by ourselves.

There is not need to restore r10, r11 and cr registers at this end of ITLBmiss
handler as they are saved again to the same place in ITLBError handler we are
jumping to.

When a PMD entry is valid, _PMD_PRESENT is set. Therefore, forcing that bit
during TLB loading is useless.

after fixing DAR as they are saved again to the same place just after.

Since coming 469d62be9263b92f2c3329540cbb1c076111f4f3, SPRG2 is used as a
scratch register just like SPRG0 and SPRG1. So Declare it as such and fix
the comment which is not valid anymore since that commit.

SCRATCH0 and SCRATCH1 are only used in Exceptions prologs where no other
exception can happen. There is therefore no need to preserve them accross
TLB handlers, we can use them there as in other exceptions. One of the
advantages is that they do not suffer CPU6 errata unlike M_TW register.

DataAccess exception is never generated by MPC8xx so do the job directly where
it is used to avoid an unnecessary branching.

Exception InstructionAccess does not exist on MPC8xx. No need to branch there
from somewhere else.
Handling can be done directly in InstructionTLBError Exception.

Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins.
We need to keep IRQ assignment for PCI devices during runtime power
