IA-64 is special and treats pgd_offset_k() differently to pgd_offset(),
using different formulae to calculate the indices into the kernel and user
PGDs. The index into the user PGDs takes into account the region number,
but the index into the kernel (init_mm) PGD always assumes a predefined
kernel region number. Commit 974b9b2c68 ("mm: consolidate pte_index() and
pte_offset_*() definitions") made IA-64 use a generic pgd_offset_k() which
incorrectly used pgd_index() for kernel page tables. As a result, the
index into the kernel PGD was going out of bounds and the kernel hung
during early boot.
Allow overrides of pgd_offset_k() and override it on IA-64 with the old
implementation that will correctly index the kernel PGD.

Impose a limit on the number of watches that a user can hold so that
they can't use this mechanism to fill up all the available memory.
This is done by putting a counter in user_struct that's incremented when
a watch is allocated and decreased when it is released. If the number
exceeds the RLIMIT_NOFILE limit, the watch is rejected with EAGAIN.
This can be tested by the following means:
(1) Create a watch queue and attach it to fd 5 in the program given - in
this case, bash:
keyctl watch_session /tmp/nlog /tmp/gclog 5 bash
(2) In the shell, set the maximum number of files to, say, 99:
ulimit -n 99
(3) Add 200 keyrings:
for ((i=0; i<200; i++)); do keyctl newring a$i @s || break; done
(4) Try to watch all of the keyrings:
for ((i=0; i<200; i++)); do echo $i; keyctl watch_add 5 %:a$i || break; done
This should fail when the number of watches belonging to the user hits
99.
(5) Remove all the keyrings and all of those watches should go away:
for ((i=0; i<200; i++)); do keyctl unlink %:a$i; done
(6) Kill off the watch queue by exiting the shell spawned by
watch_session.

Lastly, a bit of fallout from the async buffered reads, where we now

got a cleanup along the way so that it's now easier to read (and

A page never changes its zone number. The zone number happens to be
stored in the same word as other bits which are modified, but the zone
number bits will never be modified by any other write, so it can accept
a reload of the zone bits after an intervening write and it don't need
to use READ_ONCE(). Thus, annotate this data race using
ASSERT_EXCLUSIVE_BITS() to also assert that there are no concurrent
writes to it.

The write is under lru_lock, but the read is done as lockless. The scan
count is used to determine how aggressively the anon and file LRU lists
should be scanned. Load tearing could generate an inefficient heuristic,
so fix it by adding READ_ONCE() for the read.

This remoes the code from the COW path to call debug_dma_assert_idle(),
which was added many years ago.
Google shows that it hasn't caught anything in the 6+ years we've had it
apart from a false positive, and Hugh just noticed how it had a very
unfortunate spinlock serialization in the COW path.
He fixed that issue the previous commit (a85ffd59bd: "dma-debug: fix
debug_dma_assert_idle(), use rcu_read_lock()"), but let's see if anybody
even notices when we remove this function entirely.
NOTE! We keep the dma tracking infrastructure that was added by the
commit that introduced it. Partly to make it easier to resurrect this
debug code if we ever deside to, and partly because that tracking by pfn
and offset looks quite reasonable.
The problem with this debug code was simply that it was expensive and
didn't seem worth it, not that it was wrong per se.

Pull more timer updates from Thomas Gleixner:
"A set of posix CPU timer changes which allows to defer the heavy work
of posix CPU timers into task work context. The tick interrupt is
reduced to a quick check which queues the work which is doing the
heavy lifting before returning to user space or going back to guest
mode. Moving this out is deferring the signal delivery slightly but
posix CPU timers are inaccurate by nature as they depend on the tick
so there is no real damage. The relevant test cases all passed.
This lifts the last offender for RT out of the hard interrupt context
tick handler, but it also has the general benefit that the actual
heavy work is accounted to the task/process and not to the tick
interrupt itself.
Further optimizations are possible to break long sighand lock hold and
interrupt disabled (on !RT kernels) times when a massive amount of
posix CPU timers (which are unpriviledged) is armed for a
task/process.
This is currently only enabled for x86 because the architecture has to
ensure that task work is handled in KVM before entering a guest, which
was just established for x86 with the new common entry/exit code which
got merged post 5.8 and is not the case for other KVM architectures"

Currently, the only way to remove MFD children is with a call to
mfd_remove_devices, which will remove all the children. Under
some circumstances it is useful to remove only a subset of the
child devices. For example if some additional clean up is required
between removal of certain child devices.
To accomplish this a level field is added to mfd_cell, the normal
mfd_remove_devices is modified to not remove devices that are set
to a higher level and a corresponding mfd_remove_devices_late
function is added to remove those children.

The current implementation performs checking in the i2c_probe()
function of the variant_code but does this immediately after the
containing struct has been initialised as all zero. This means the
check for variant code will always default to using the BB tables
and will never select AD. The variant code is subsequently set
by device_init() and later used by the RTC so really it's a little
fortunate this mismatch works.
This update adds raw I2C read access functionality to read the chip
and variant/revision information (common to all revisions) so that
it can subsequently correctly choose the proper regmap tables for
real initialisation.

Currently, when a child platform device (sometimes referred to as a
sub-device) is registered via the Multi-Functional Device (MFD) API,
the framework attempts to match the newly registered platform device
with its associated Device Tree (OF) node. Until now, the device has
been allocated the first node found with an identical OF compatible
string. Unfortunately, if there are, say for example '3' devices
which are to be handled by the same driver and therefore have the same
compatible string, each of them will be allocated a pointer to the
*first* node.
An example Device Tree entry might look like this:
mfd_of_test {
compatible = "mfd,of-test-parent";
#address-cells = <0x02>;
#size-cells = <0x02>;
child@aaaaaaaaaaaaaaaa {
compatible = "mfd,of-test-child";
reg = <0xaaaaaaaa 0xaaaaaaaa 0 0x11>,
<0xbbbbbbbb 0xbbbbbbbb 0 0x22>;
};
child@cccccccc {
compatible = "mfd,of-test-child";
reg = <0x00000000 0xcccccccc 0 0x33>;
};
child@dddddddd00000000 {
compatible = "mfd,of-test-child";
reg = <0xdddddddd 0x00000000 0 0x44>;
};
};
When used with example sub-device registration like this:
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 0, "mfd,of-test-child"),
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child"),
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 2, "mfd,of-test-child")
};
... the current implementation will result in all devices being allocated
the first OF node found containing a matching compatible string:
[0.712511] mfd-of-test-child mfd-of-test-child.0: Probing platform device: 0
[0.712710] mfd-of-test-child mfd-of-test-child.0: Using OF node: child@aaaaaaaaaaaaaaaa
[0.713033] mfd-of-test-child mfd-of-test-child.1: Probing platform device: 1
[0.713381] mfd-of-test-child mfd-of-test-child.1: Using OF node: child@aaaaaaaaaaaaaaaa
[0.713691] mfd-of-test-child mfd-of-test-child.2: Probing platform device: 2
[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@aaaaaaaaaaaaaaaa
After this patch each device will be allocated a unique OF node:
[0.712511] mfd-of-test-child mfd-of-test-child.0: Probing platform device: 0
[0.712710] mfd-of-test-child mfd-of-test-child.0: Using OF node: child@aaaaaaaaaaaaaaaa
[0.713033] mfd-of-test-child mfd-of-test-child.1: Probing platform device: 1
[0.713381] mfd-of-test-child mfd-of-test-child.1: Using OF node: child@cccccccc
[0.713691] mfd-of-test-child mfd-of-test-child.2: Probing platform device: 2
[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@dddddddd00000000
Which is fine if all OF nodes are identical. However if we wish to
apply an attribute to particular device, we really need to ensure the
correct OF node will be associated with the device containing the
correct address. We accomplish this by matching the device's address
expressed in DT with one provided during sub-device registration.
Like this:
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child", 0xdddddddd00000000),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 2, "mfd,of-test-child", 0xaaaaaaaaaaaaaaaa),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 3, "mfd,of-test-child", 0x00000000cccccccc)
};
This will ensure a specific device (designated here using the
platform_ids; 1, 2 and 3) is matched with a particular OF node:
[0.712511] mfd-of-test-child mfd-of-test-child.0: Probing platform device: 0
[0.712710] mfd-of-test-child mfd-of-test-child.0: Using OF node: child@dddddddd00000000
[0.713033] mfd-of-test-child mfd-of-test-child.1: Probing platform device: 1
[0.713381] mfd-of-test-child mfd-of-test-child.1: Using OF node: child@aaaaaaaaaaaaaaaa
[0.713691] mfd-of-test-child mfd-of-test-child.2: Probing platform device: 2
[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@cccccccc
This implementation is still not infallible, hence the mention of
"best effort" in the commit subject. Since we have not *insisted* on
the existence of 'reg' properties (in some scenarios they just do not
make sense) and no device currently uses the new 'of_reg' attribute,
we have to make an on-the-fly judgement call whether to associate the
OF node anyway. Which we do in cases where parent drivers haven't
specified a particular OF node to match to. So there is a *slight*
possibility of the following result (note: the implementation here is
convoluted, but it shows you one means by which this process can
still break):
/*
* First entry will match to the first OF node with matching compatible
* Second will fail, since the first took its OF node and is no longer available
* Third will succeed
*/
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child"),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 2, "mfd,of-test-child", 0xaaaaaaaaaaaaaaaa),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 3, "mfd,of-test-child", 0x00000000cccccccc)
};
The result:
[0.753869] mfd-of-test-parent mfd_of_test: Registering 3 devices
[0.756597] mfd-of-test-child: Failed to locate of_node [id: 2]
[0.759999] mfd-of-test-child mfd-of-test-child.1: Probing platform device: 1

[0.761183] mfd-of-test-child mfd-of-test-child.2: No OF node associated with this device

[0.761899] mfd-of-test-child mfd-of-test-child.3: Using OF node: child@cccccccc
We could code around this with some pre-parsing semantics, but the
added complexity required to cover each and every corner-case is not
justified. Merely patching the current failing (via this patch) is
already working with some pretty small corner-cases. Other issues
should be patched in the parent drivers which can be achieved simply
by implementing OF_MFD_CELL_REG().

nf_ct_frag6_gather is part of nf_defrag_ipv6.ko, not ipv6 core.
The current use of the netfilter ipv6 stub indirections causes a module
dependency between ipv6 and nf_defrag_ipv6.
This prevents nf_defrag_ipv6 module from being removed because ipv6 can't
be unloaded.
Remove the indirection and always use a direct call. This creates a
depency from nf_conntrack_bridge to nf_defrag_ipv6 instead:
modinfo nf_conntrack
