We need to ensure there is enough headroom to push extra header,
but we also need to check if we are allowed to change headers.
skb_cow_head() is the proper helper to deal with this.
Fixes Ethernet<->WiFi bridge for Raspberry Pi and probably other devices.

The problem is caused by the incorrect handling of the parent inode's
i_nlink count for the dentry to be RENAME_EXCHANGED. There are 3 cases
to consider. Assume we want to RENAME_EXCHANGE struct dentry *a and
struct dentry *b, and inode_a is pointed to by dentry_a, inode_b is
pointed to by dentry_b:
1. If inode_a is a directory, but inode_b isn't, then we must decrease
the i_nlink count of old_dir_i, and increase the i_nlink of new_dir_i.
2. If inode_a isn't a directory, but inode_b is a directory, then we
must increase the i_nlink of old_dir_i, and decrease the i_nlink count
of new_dir_i.
3. If the types of inode_a and inode_b are the same, we don't change the
i_nlink for either old_dir_i or new_dir_i.

"ar8216: adjust ATU flushing in case of link changes"
introduced portwise flushing on link down events. Now the ARL table could
be in a chaotic state after boot where ar8xxx_sw_get_arl_table looped
forever (depending on the entries collected while booting).
Fixes FS#384.

When memory is tight, modules may need to be loaded into vmalloc()
space. The code then has to generate jump trampolines which enable
relocations between vmalloc space and physical address space.
The code had a bug that was freeing these trampolines even when the
module was successfully loaded.

Refresh patches for all targets that support kernel 4.4.
Compile-tested on all targets that use kernel 4.4 and aren't marked
broken, except arc770 and arch38 due to broken toolchain.

This is a pure rename without any changes. It makes maintaining bgmac
simpler and will hopefully make adding new kernel a bit easier.

Running ar8327_get_arl_entry() early after boot leads to MDIO related system
lockups on several devices using this driver.
Since dumping the ARL table contens is an optional, uncritical feature, simply
disable the code for now.

This fixes hangs in igb that happen if the update call interrupts an
already existing dev_get_stats call. In that case the calling CPU
deadlocks because it's trying to acquire the same spinlock recursively.

The priv->vlan_id member is of size AR8X16_MAX_VLANS, not AR8X16_MAX_PORTS,

This patch is part of a series adding support for 0x9200 and 0x9300. The
prior was merged into the upstream kernel while the latter was not due
to lack of testers. Drop the patch as it is untested and most likely
unused.

The si3210 is a SLIC device providing a complete analog telephone
interface and therefore frequently used in soho router.
The si3210 have a native spi interface to be controlled by the CPU
but currently there is no dedicated driver in lede.
Adding a registration for this device in spidev allow to control the
device in user space.
This way of patching is also in line with the rationale of the spidev
driver, see: http://marc.info/?t=148145791900001&r=1&w=2
The si3210 has been also added in the DWR-512 DT to properly describe
the HW.
