We can't use dev->mod_index for selecting the interrupt routing entry,
because it's not an index into interrupt routing table. It will be even
wrong on a machine with 2 CPUs (4 cores). But all needed information is
contained in the PAT entries for the serial ports. mod[0] contains the
iosapic address and mod_info has some indications for the interrupt
input (at least it looks like it). This patch implements the searching
for the right iosapic and uses this interrupt input information.

The parisc architecture does not have a pte special bit. As a result,
special mappings are handled with the VM_PFNMAP and VM_MIXEDMAP flags.
VM_MIXEDMAP mappings may or may not have a "struct page" backing. When
pfn_valid() is false, there is no "struct page" backing. Otherwise, they
are treated as normal pages.
The FireGL driver uses the VM_MIXEDMAP without a backing "struct page".
This treatment caused a panic due to a TLB data miss in
update_mmu_cache. This appeared to be in the code generated for
page_address(). We were in fact using a very circular bit of code to
determine the physical address of the PFN in various cache routines.
This wasn't valid when there was no "struct page" backing. The needed
address can in fact be determined simply from the PFN itself without
using the "struct page".
The attached patch updates update_mmu_cache(), flush_cache_mm(),
flush_cache_range() and flush_cache_page() to check pfn_valid() and to
directly compute the PFN physical and virtual addresses.

vmpressure is called synchronously from reclaim where the target_memcg
is guaranteed to be alive but the eventfd is signaled from the work
queue context. This means that memcg (along with vmpressure structure
which is embedded into it) might go away while the work item is pending
which would result in use-after-release bug.
We have two possible ways how to fix this. Either vmpressure pins memcg
before it schedules vmpr->work and unpin it in vmpressure_work_fn or
explicitely flush the work item from the css_offline context (as
suggested by Tejun).
This patch implements the later one and it introduces vmpressure_cleanup
which flushes the vmpressure work queue item item. It hooks into
mem_cgroup_css_offline after the memcg itself is cleaned up.

__isolate_lru_page() returns EINVAL for PageUnevictable(page).
For lru_add_page_tail(), it means we should not set PageUnevictable()
for tail pages unless we're sure that it will go to LRU_UNEVICTABLE.
Let's just copy PG_active and PG_unevictable from head page in
__split_huge_page_refcount(), it will simplify lru_add_page_tail().
This will fix one more bug in lru_add_page_tail(): if
page_evictable(page_tail) is false and PageLRU(page) is true, page_tail
will go to the same lru as page, but nobody cares to sync page_tail
active/inactive state with page. So we can end up with inactive page on
active lru. The patch will fix it as well since we copy PG_active from
head page.

vma_adjust() does vma_set_policy(vma, vma_policy(next)) and this
is doubly wrong:
1. This leaks vma->vm_policy if it is not NULL and not equal to
next->vm_policy.
This can happen if vma_merge() expands "area", not prev (case 8).
2. This sets the wrong policy if vma_merge() joins prev and area,
area is the vma the caller needs to update and it still has the
old policy.
Revert commit 1444f92c84 ("mm: merging memory blocks resets

IPoIB's required behaviour w.r.t to the pkey used by the device is the following:
- For "parent" interfaces (e.g ib0, ib1, etc) who are created
automatically as a result of hot-plug events from the IB core, the
driver needs to take whatever pkey vlaue it finds in index 0, and
stick to that index.
- For child interfaces (e.g ib0.8001, etc) created by admin directive,
the driver needs to use and stick to the value provided during its
creation.
In SR-IOV environment its possible for the VF probe to take place
before the cloud management software provisions the suitable pkey for
the VF in the paravirtualed PKEY table index 0. When this is the case,
the VF IB stack will find in index 0 an invalide pkey, which is all
zeros.
Moreover, the cloud managment can assign the pkey value at index 0 at
any time of the guest life cycle.
The correct behavior for IPoIB to address these requirements for
parent interfaces is to use PKEY_CHANGE event as trigger to optionally
re-init the device pkey value and re-create all the relevant resources
accordingly, if the value of the pkey in index 0 has changed (from
invalid to valid or from valid value X to invalid value Y).
This patch enhances the heavy flushing code which is triggered by pkey
change event, to behave correctly for parent devices. For child
devices, the code remains the same, namely chases pkey value and not
index.

Currently, QP1 is created using pkey index 0. This patch simply looks
for the index containing the default pkey, rather than hard-coding
pkey index 0.
This change will have no effect in native mode, since QP0 and QP1 are
created before the SM configures the port, so pkey table will still be
the default table defined by the IB Spec, in C10-123: "If non-volatile
storage is not used to hold P_Key Table contents, then if a PM
(Partition Manager) is not present, and prior to PM initialization of
the P_Key Table, the P_Key Table must act as if it contains a single
valid entry, at P_Key_ix = 0, containing the default partition
key. All other entries in the P_Key Table must be invalid."
Thus, in the native mode case, the driver will find the default pkey
at index 0 (so it will be no different than the hard-coding).
However, in SR-IOV mode, for VFs, the pkey table may be
paravirtualized, so that the VF's pkey index zero may not necessarily
be mapped to the real pkey index 0. For VFs, therefore, it is
important to find the virtual index which maps to the real default
pkey.
This commit does the following for QP1 creation:
1. Find the pkey index containing the default pkey, and use that index
if found. ib_find_pkey() returns the index of the
limited-membership default pkey (0x7FFF) if the full-member default
pkey is not in the table.
2. If neither form of the default pkey is found, use pkey index 0
(previous behavior).

When creating tunnel QPs for special QP tunneling, look for the
default pkey in the slave's virtual pkey table. If it is present, use
the real pkey index where the default pkey is located.
If the default pkey is not found in the pkey table, use the real pkey
index which is stored at index 0 in the slave's virtual pkey table
(this is the current behavior).
This change is required to support cloud computing, where the
paravirtualized index of the default pkey is moved to index 1 or
higher. The pkey at paravirtualized index 0 is used for the default
IPoIB interface created by the VF.
Its possible for the pkey value at paravirtualized index 0 to be
invalid (zero) at VF probe time (pkey index 0 is mapped to real pkey
index 127, which contains pkey = 0).
At some point after the VF probe, the cloud computing interface at the
hypervisor maps virtual index 0 for the VF to the pkey index
containing the pkey that IPoIB will use in its operation. However,
when the tunnel QP is created, the pkey at the slave's virtual index 0
is still mapped to the invalid pkey index, so tunnel QP creation
fails.
This commit causes the hypervisor to search for the default pkey in
the slave's pkey table -- and this pkey is present in the table (at
index > 0) at tunnel QP creation time, so that the tunnel QP creation
will succeed.

We have:
- A build failure fix for the NCI SPI transport layer due to a
missing CRC_CCITT Kconfig dependency.
- A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11
merge window but the typical terminology for loading a firmware to a
target is firmware download rather than upload. In order to avoid any
confusion in a file exported to userspace, we rename this command into
CMD_FW_DOWNLOAD.
