This reverts commit d2aae8477c.
It is completely and utterly broken. Module install should not build
any files, and adding broken dependencies to "help" it build files is
complete and utter sh*t.
The kernel should not be built by root, and "make install" and "make
module_install" (that for obvious reasons need to be run as root)
absolutely must not build any files. They should only ever copy the
already-built files over.
So having dependencies for the install targets is wrong, wrong, wrong.
If you try to install a kernel without building it first, you *should*
get errors. The build system shouldn't try to help root build the files.

zswap is a thin backend for frontswap that takes pages that are in the
process of being swapped out and attempts to compress them and store
them in a RAM-based memory pool. This can result in a significant I/O
reduction on the swap device and, in the case where decompressing from
RAM is faster than reading from the swap device, can also improve
workload performance.
It also has support for evicting swap pages that are currently
compressed in zswap to the swap device on an LRU(ish) basis. This
functionality makes zswap a true cache in that, once the cache is full,
the oldest pages can be moved out of zswap to the swap device so newer
pages can be compressed and stored in zswap.
This patch adds the zswap driver to mm/

zbud is an special purpose allocator for storing compressed pages. It
is designed to store up to two compressed pages per physical page.
While this design limits storage density, it has simple and
deterministic reclaim properties that make it preferable to a higher
density approach when reclaim will be used.
zbud works by storing compressed pages, or "zpages", together in pairs
in a single memory page called a "zbud page". The first buddy is "left
justifed" at the beginning of the zbud page, and the last buddy is
"right justified" at the end of the zbud page. The benefit is that if
either buddy is freed, the freed buddy space, coalesced with whatever
slack space that existed between the buddies, results in the largest
possible free region within the zbud page.
zbud also provides an attractive lower bound on density. The ratio of
zpages to zbud pages can not be less than 1. This ensures that zbud can
never "do harm" by using more pages to store zpages than the
uncompressed zpages would have used on their own.
This implementation is a rewrite of the zbud allocator internally used
by zcache in the driver/staging tree. The rewrite was necessary to
remove some of the zcache specific elements that were ingrained
throughout and provide a generic allocation interface that can later be
used by zsmalloc and others.
This patch adds zbud to mm/ for later use by zswap.

For the related next strcpy(), the destination length is less than 512,

more than 512.
One work flow may:
openprom_sunos_ioctl() -> if (cmd == OPROMSETOPT)
getstrings() -> will alloc buffer with size 'OPROMMAXPARAM'.
opromsetopt() -> devide the buffer into 'var' and 'value'
of_set_property() -> pass
prom_setprop() -> pass
ldom_set_var()
And do not mind the additional 4 alignment buffer increasing, since
'sizeof(pkt) - sizeof(pkt.header)' is 4 alignment at least.

various Renesas SoCs. Furthermore support is added for the NXP PCA9685
LED controller. Another big chunk is the sysfs interface which has been
in the works for quite some time.
The remaining patches are a random assortment of cleanups and fixes.

Merge tag 'arc-v3.11-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull second set of ARC architecture updates from Vineet Gupta:
"Couple of Platform updates (Device Tree files primarily) given that
the corresponding drivers (net/ethernet/arc/*, irqctl/irq-tb10x.c)
have now been merged into your tree.
Ideally these shd have been part of same submissions, oh well..."
* tag 'arc-v3.11-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
ARC: [TB10x] Updates for irqchip driver

Pull parisc updates from Helge Deller:
"The PA-RISC updates for v3.11 include a gcc miscompilation fix,
gzip-compressed vmlinuz support, a fix in the PCI code for ATI FireGL
support on c8000 machines, a fix to prevent that %sr1 is being
clobbered and a few smaller optimizations and documentation updates"
* 'parisc-for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Fix gcc miscompilation in pa_memcpy()
parisc: Ensure volatile space register %sr1 is not clobbered
parisc: optimize mtsp(0,sr) inline assembly
parisc: switch to gzip-compressed vmlinuz kernel
parisc: document the shadow registers
parisc: more capabilities info in /proc/cpuinfo
parisc: fix LMMIO mismatch between PAT length and MASK register
The reason is that other applications like strace
think that every __NR_xx is syscall.
Also __NR_syscalls is not used by user applications/libs.

Pull networking updates from David Miller:
"This is a re-do of the net-next pull request for the current merge
window. The only difference from the one I made the other day is that
this has Eliezer's interface renames and the timeout handling changes
made based upon your feedback, as well as a few bug fixes that have
trickeled in.
Highlights:
1) Low latency device polling, eliminating the cost of interrupt
handling and context switches. Allows direct polling of a network
device from socket operations, such as recvmsg() and poll().
Currently ixgbe, mlx4, and bnx2x support this feature.
Full high level description, performance numbers, and design in
commit 0a4db187a9 ("Merge branch 'll_poll'")
From Eliezer Tamir.
2) With the routing cache removed, ip_check_mc_rcu() gets exercised
more than ever before in the case where we have lots of multicast
addresses. Use a hash table instead of a simple linked list, from
Eric Dumazet.
3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
4) Support reporting the TUN device persist flag to userspace, from
Pavel Emelyanov.
5) Allow controlling network device VF link state using netlink, from
Rony Efraim.
6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
Daniel Borkmann and Eric Dumazet.
8) Allow controlling of TCP quickack behavior on a per-route basis,
from Cong Wang.
9) Several bug fixes and improvements to vxlan from Stephen
Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
support receiving on multiple UDP ports.
10) Major cleanups, particular in the area of debugging and cookie
lifetime handline, to the SCTP protocol code. From Daniel
Borkmann.
11) Allow packets to cross network namespaces when traversing tunnel
devices. From Nicolas Dichtel.
12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
manner akin to how we monitor real network traffic via ptype_all.
From Daniel Borkmann.
13) Several bug fixes and improvements for the new alx device driver,
from Johannes Berg.
14) Fix scalability issues in the netem packet scheduler's time queue,
by using an rbtree. From Eric Dumazet.
15) Several bug fixes in TCP loss recovery handling, from Yuchung
Cheng.
16) Add support for GSO segmentation of MPLS packets, from Simon
Horman.
17) Make network notifiers have a real data type for the opaque
pointer that's passed into them. Use this to properly handle
network device flag changes in arp_netdev_event(). From Jiri
Pirko and Timo Teräs.
18) Convert several drivers over to module_pci_driver(), from Peter
Huewe.
19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
O(1) calculation instead. From Eric Dumazet.
20) Support setting of explicit tunnel peer addresses in ipv6, just
like ipv4. From Nicolas Dichtel.
21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
22) Prevent a single high rate flow from overruning an individual cpu
during RX packet processing via selective flow shedding. From
Willem de Bruijn.
23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
Dumazet.
24) Don't just drop GSO packets which are above the TBF scheduler's
burst limit, chop them up so they are in-bounds instead. Also
from Eric Dumazet.
25) VLAN offloads are missed when configured on top of a bridge, fix
from Vlad Yasevich.
26) Support IPV6 in ping sockets. From Lorenzo Colitti.
27) Receive flow steering targets should be updated at poll() time
too, from David Majnemer.
28) Fix several corner case regressions in PMTU/redirect handling due
to the routing cache removal, from Timo Teräs.
29) We have to be mindful of ipv4 mapped ipv6 sockets in
upd_v6_push_pending_frames(). From Hannes Frederic Sowa.
30) Fix L2TP sequence number handling bugs, from James Chapman."

Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong
place, but the warning should be fixed. In future I'll just take the
patch myself!
Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the
wound/wait tree from Ingo which is already merged.
Major changes:
AMD finally released the dynamic power management code for all their
GPUs from r600->present day, this is great, off by default for now but
also a huge amount of code, in fact it is most of this pull request.
Since it landed there has been a lot of community testing and Alex has
sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostly
I've been banging on this quite a lot due to the size of it, and it
seems to okay on everything I've tested it on."
