Refactor base port operations into new file; 8250_port.c.
Legacy irq handling, RSA port support, port storage for universal
driver, driver definition, module parameters and linkage remain in
8250_core.c
The source file split and resulting modules is diagrammed below:
8250_core.c ====> 8250_core.c __
\ \
\ +-- 8250.ko (alias 8250_core)
\ 8250_pnp.c __/ (universal driver)
\
=> 8250_port.c __
\
+-- 8250_base.ko
8250_dma.c __/ (port operations)

The functionality of ext3 is fully supported by ext4 driver. Major
distributions (SUSE, RedHat) already use ext4 driver to handle ext3
filesystems for quite some time. There is some ugliness in mm resulting
from jbd cleaning buffers in a dirty page without cleaning page dirty
bit and also support for buffer bouncing in the block layer when stable
pages are required is there only because of jbd. So let's remove the
ext3 driver. This saves us some 28k lines of duplicated code.

Currently when some error happened in ->acquire_dquot(), dqget() just
returned NULL. That was indistinguishable from a case when e.g. someone
run quotaoff and so was generally silently ignored. However
->acquire_dquot() can fail because of ENOSPC or EIO in which case user
should better know. So propagate error up from ->acquire_dquot properly.

There have been several requests for a primitive that waits for
grace periods for several RCU flavors concurrently, so this
commit creates it. This is a variadic macro, and you pass in
the call_rcu() functions of the flavors of RCU that you wish to
wait for.
Note that you cannot pass in call_srcu() for two reasons: (1) This
would result in a type mismatch and (2) You need to specify which
srcu_struct you want to use. Handle this by creating a wrapper
function for your SRCU domain, for example:
void call_srcu_mine(struct rcu_head *head, rcu_callback_t func)
{
call_srcu(&ss_mine, head, func);
}
You can then do something like this:
synchronize_rcu_mult(call_srcu_mine, call_rcu, call_rcu_sched);

allow polling for grace-period completion, with an actual wait for a

soon after the corresponding get_state_synchronize_rcu(). However,
these functions work only for vanilla RCU. This commit adds the

Reorganize struct msi_desc so it could be reused by other MSI
drivers. We have the following layout now:
struct msi_desc {
/* Shared device/bus independent data */
...
union {
/* PCI specific data */
struct {
...
};
};
};
We need to have anonymous union and a anonymous structure for the PCI
fields, otherwise we would have to change all instances using these
fields.
For non PCI devices we will enforce a proper namespace and a non
anonymous structure.

Add a dev_flags bit, PCI_DEV_FLAGS_VPD_REF_F0, to access VPD through
function 0 to provide VPD access on other functions. This is for hardware
devices that provide copies of the same VPD capability registers in
multiple functions. Because the kernel expects that each function has its
own registers, both the locking and the state tracking are affected by VPD
accesses to different functions.
On such devices for example, if a VPD write is performed on function 0,
*any* later attempt to read VPD from any other function of that device will
hang. This has to do with how the kernel tracks the expected value of the
F bit per function.
Concurrent accesses to different functions of the same device can not only
hang but also corrupt both read and write VPD data.
When hangs occur, typically the error message:
vpd r/w failed. This is likely a firmware bug on this device.
will be seen.
Never set this bit on function 0 or there will be an infinite recursion.

Allows putting a VXLAN device into a new flow-based mode in which
skbs with a ip_tunnel_info dst metadata attached will be encapsulated
according to the instructions stored in there with the VXLAN device
defaults taken into consideration.
Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is
set, the packet processing will populate a ip_tunnel_info struct for
each packet received and attach it to the skb using the new metadata
dst. The metadata structure will contain the outer header and tunnel
header fields which have been stripped off. Layers further up in the
stack such as routing, tc or netfitler can later match on these fields
and perform forwarding. It is the responsibility of upper layers to
ensure that the flag is set if the metadata is needed. The flag limits
the additional cost of metadata collecting based on demand.
This prepares the VXLAN device to be steered by the routing and other
subsystems which allows to support encapsulation for a large number
of tunnel endpoints and tunnel ids through a single net_device which
improves the scalability.
It also allows for OVS to leverage this mode which in turn allows for
the removal of the OVS specific VXLAN code.
Because the skb is currently scrubed in vxlan_rcv(), the attachment of
the new dst metadata is postponed until after scrubing which requires
the temporary addition of a new member to vxlan_metadata. This member
is removed again in a later commit after the indirect VXLAN receive API
has been removed.

Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop via
helper functions. These functions may change skb->data/hlen which are
cached by some JITs to improve performance of ld_abs/ld_ind instructions.
Therefore JITs need to recognize bpf_skb_vlan_push/pop() calls,
re-compute header len and re-cache skb->data/hlen back into cpu registers.
Note, skb->data/hlen are not directly accessible from the programs,
so any changes to skb->data done either by these helpers or by other
TC actions are safe.
eBPF JIT supported by three architectures:
- arm64 JIT is using bpf_load_pointer() without caching, so it's ok as-is.
- x64 JIT re-caches skb->data/hlen unconditionally after vlan_push/pop calls
(experiments showed that conditional re-caching is slower).
- s390 JIT falls back to interpreter for now when bpf_skb_vlan_push() is present
in the program (re-caching is tbd).
These helpers allow more scalable handling of vlan from the programs.
Instead of creating thousands of vlan netdevs on top of eth0 and attaching
TC+ingress+bpf to all of them, the program can be attached to eth0 directly
and manipulate vlans as necessary.

Remove clk.h from clk-provider.h so that we can clearly split clk
providers from clk consumers. This will allow us to quickly
detect when clock providers are using the consumer APIs by
looking at the includes.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are using
it. Also add in a clkdev.h include that was missing in a file
using clkdev APIs.

The file read/write functions for bools have no special dependencies
on debugfs internals and are sufficiently non-trivial to be worth
exporting so clients can re-use the implementation.

This function no longer exists after commit a49b116dcb12
(clockevents: Cleanup dead cpu explicitely, 2015-04-03). Remove
the prototype and the stub function.

Some drivers are directly accessing the ->polarity field in pwm_device.
Add a helper to retrieve the current polarity so that we can easily move
this field elsewhere (required to support atomic update).

The PWM argument is not modified in PWM property accessors, make it a
const argument so that the accessors can be used from sysfs.
