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.

This adds support for describing GPIO chips placed on PCIe cards. Thanks
to this we get working 2.4 GHz LED on Tenda AC9.

It is not needed for anything on the system and skipping this saves some
build time, especially in cases where there is nothing to do.

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.

This backports fixes for setting of_node and making it possible to read

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.
Runtime-tested on ar71xx, octeon, ramips and x86/64.

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