Documentation: update CodingStyle tips for Emacs users

With the previous Emacs tips example the kernel style was made available
for files in the kernel-tree only. This patch updates the tip to add a
separate cc-mode indent style ("linux-tabs-only"). This makes it easy to
switch between different indent styles and also makes the kernel style
easily available for any filetype mode (c++, awk, ...) that is managed
by the Emacs cc-mode.

epoll: drop max_user_instances and rely only on max_user_watches

Linus suggested to put limits where the money is, and max_user_watches
already does that w/out the need of max_user_instances.  That has the
advantage to mitigate the potential DoS while allowing pretty generous
default behavior.

Allowing top 4% of low memory (per user) to be allocated in epoll watches,
we have:

LOMEM    MAX_WATCHES (per user)
512MB    ~178000
1GB      ~356000
2GB      ~712000

A box with 512MB of lomem, will meet some challenge in hitting 180K
watches, socket buffers math teaches us.  No more max_user_instances
limits then.

This causes strange problem that the parent mem_cgroup dies while child

Fix OOPS in mmap_region() when merging adjacent VM_LOCKED file segments

As of commit ba470de43188cdbff795b5da43a1474523c6c2fb ("map: handle
mlocked pages during map, remap, unmap") we now use the 'vma' variable
at the end of mmap_region() to handle the page-in of newly mapped
mlocked pages.

However, if we merged adjacent vma's together, the vma we're using may
be stale.  We historically consciously avoided using it after the merge
operation, but that got overlooked when redoing the locked page
handling.

This commit simplifies mmap_region() by doing any vma merges early,
avoiding the issue entirely, and 'vma' will always be valid.  As pointed
out by Hugh Dickins, this depends on any drivers that change the page
offset of flags to have set one of the VM_SPECIAL bits (so that they
cannot trigger the early merge logic), but that's true in general.

firewire: sbp2: add workarounds for 2nd and 3rd generation iPods

According to https://bugs.launchpad.net/bugs/294391
  - 3rd generation iPods need the "fix capacity" workaround after all
    (apparently they crash after the last sector was accessed),
  - 2nd generation iPods need the "128 kB maximum request size"
    workaround.

Alas both iPod generations feature the same model ID in the config ROM,
hence we can only define a shared quirks list entry for them.  Luckily
the fix capacity workaround did not show a negative effect in Jarod's
tests with 2nd gen. iPod.

A side note:  Apple computers in target mode (or at least an x86 Mac
mini) don't have firmware_version and model_id, hence none of the iPod
