Kirill A. Shutemov e180cf806a thp, mm: avoid PageUnevictable on active/inactive lru lists
active/inactive lru lists can contain unevicable pages (i.e.  ramfs pages
that have been placed on the LRU lists when first allocated), but these
pages must not have PageUnevictable set - otherwise shrink_[in]active_list
goes crazy:

kernel BUG at /home/space/kas/git/public/linux-next/mm/vmscan.c:1122!

1090 static unsigned long isolate_lru_pages(unsigned long nr_to_scan,
1091                 struct lruvec *lruvec, struct list_head *dst,
1092                 unsigned long *nr_scanned, struct scan_control *sc,
1093                 isolate_mode_t mode, enum lru_list lru)
1094 {
...
1108                 switch (__isolate_lru_page(page, mode)) {
1109                 case 0:
...
1116                 case -EBUSY:
...
1121                 default:
1122                         BUG();
1123                 }
1124         }
...
1130 }

__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.

Naoya Horiguchi ef2a2cbdda mm/swap.c: clear PageActive before adding pages onto unevictable list
As a result of commit 13f7f78981 ("mm: pagevec: defer deciding which
LRU to add a page to until pagevec drain time"), pages on unevictable
lists can have both of PageActive and PageUnevictable set.  This is not
only confusing, but also corrupts page migration and
shrink_[in]active_list.

This patch fixes the problem by adding ClearPageActive before adding
pages into unevictable list.  It also cleans up VM_BUG_ONs.

Commit 3105b86a9f ("mm: sched: numa: Control enabling and disabling of

I believe the intention was to use this in place of sched_feat_numa(NUMA).

Currently, if SCHED_DEBUG is not defined, sched_feat_numa(NUMA) will
never be changed from the initial "false".

Oleg Nesterov 3964acd0db mm: mempolicy: fix mbind_range() && vma_adjust() interaction
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
mempolicy") which introduced these problems.

Change mbind_range() to recheck mpol_equal() after vma_merge() to fix
the problem that commit tried to address.

Erez Shitrit c290414169 IPoIB: Fix pkey change flow for virtualization environments
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.

Jack Morgenstein ef5ed4166f IB/core: Create QP1 using the pkey index which contains the default pkey
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).

Jack Morgenstein 3eac103f83 IB/mlx4: Use default pkey when creating tunnel QPs
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.

 - 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

This patch fixes an issue wherein association would fail on P2P
interfaces. This happened because we are checking priv->mode
against NL80211_IFTYPE_STATION. While this check is correct for
infrastructure stations, it would fail P2P clients for which mode
is NL80211_IFTYPE_P2P_CLIENT.

Better check would be bss_role which has only 2 values: STA/AP.

Paul Walmsley 067e710b9a ARM: 7801/1: v6: prevent gcc 4.5 from reordering extended CP15 reads above is_smp() test
Commit 621a0147d5 ("ARM: 7757/1: mm:
don't flush icache in switch_mm with hardware broadcasting") breaks
the boot on OMAP2430SDP with omap2plus_defconfig.  Tracked to an
undefined instruction abort from the CP15 read in
cache_ops_need_broadcast().  It turns out that gcc 4.5 reorders the
extended CP15 read above the is_smp() test.  This breaks ARM1136 r0
cores, since they don't support several CP15 registers that later ARM
cores do.  ARM1136JF-S TRM section 3.2.1 "Register allocation" has the
details.

So mark the extended CP15 read as clobbering memory, which prevents
the compiler from reordering it before the is_smp() test.  Russell
states that the code generated from this approach is preferable to
marking the inline asm as volatile.  Remove the existing condition
code clobber as it's obsolete, per Nico's post:

    http://www.spinics.net/lists/arm-kernel/msg261208.html
