Hi,
This is a series to add a pool for atomic allocations for arm64. It was
previously suggested to try and share more code with arm. I did some
refactoring to have arm use genalloc and pull out some of the remapping
code. The end result is a negative diffstat overall for arm dma-mapping.c.
After allocating an address from a particular genpool,
there is no good way to verify if that address actually
belongs to a genpool. Introduce addr_in_gen_pool which
will return if an address plus size falls completely
within the genpool range.

This is mostly cleanups. Patch 1 fixes a minor bug; it might make sense
to backport it.
Patch 3 removes the vsyscall mapping when vsyscall=none.
Patches 4 and 5 remove everything except gtod from the vvar page; the
other vvars weren't really necessary.
Patch 2, 6, 7, and 8 are pure cleanups.

The vdso has supported alternatives for a while; use them instead of
a vvar to select the vgetcpu mode.

I see no point in having an unusable read-only page sitting at
0xff60 when vsyscall=none. Instead, skip mapping it and
remove it from /proc/PID/maps.
I kept the ratelimited warning when programs try to use a vsyscall
in this mode, since it may help admins avoid confusion.
mips:allmodconfig fails in 3.16-rc1 with lots of undefined symbols.
arch/mips/net/bpf_jit.c: In function 'is_load_to_a':

this function)

I think that the jiffies vvar was once used for the vgetcpu cache.
That code is long gone, so let's just make jiffies be a normal
variable.

caused warn_bad_vsyscall to output garbage in the
vsyscall_64.c is just vsyscall emulation. Tidy it up accordingly.
If my comment editing offends anyone, let me know and I can fix it.

This code exists for the sole purpose of making the vsyscall page
look sort of like real userspace memory. Move it so that it lives
with the rest of the vsyscall code.

This fixes use-after-free of epi-fllink.next inside list loop macro.
This loop actually releases elements in the body. List is rcu-protected
but here we cannot hold rcu_read_lock because we need to lock mutex inside.
Obvious solution is to use list_for_each_entry_safe(). RCU-ness isn't essential
