#1375270 — [PATCH 4.4 028/210] s390/cpumf: add missing lpp magic initialization

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiko Carstens <heiko.carstens@de.ibm.com>

commit 8f100bb1ff27873dd71f636da670e503b9ade3c6 upstream.

Add the missing lpp magic initialization for cpu 0. Without this all
samples on cpu 0 do not have the most significant bit set in the
program parameter field, which we use to distinguish between guest and
host samples if the pid is also 0.

We did initialize the lpp magic in the absolute zero lowcore but
forgot that when switching to the allocated lowcore on cpu 0 only.

#1375275 — [PATCH 4.4 182/210] clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexander Kochetkov <al.kochet@gmail.com>

commit e8b63288b37dbb8457b510c9d96f6006da4653f6 upstream.

hclk_cpubus needs to keep running because it is needed for devices like
the rom, i2s0 or spdif to be accessible via cpu. Without that all
accesses to devices (readl/writel) return wrong data. So add it
to the list of critical clocks.

#1375277 — [PATCH 4.4 170/210] kbuild/mkspec: fix grub2 installkernel issue

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Kosina <jkosina@suse.cz>

commit c8b08ca558c0067bc9e15ce3f1e70af260410bb2 upstream.

mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

From: Jenny Derzhavetz <jennyf@mellanox.com>

commit 6d1fba0c2cc7efe42fd761ecbba833ed0ea7b07e upstream.

When we receive an event that triggers connection termination,
we have a a couple of things we may want to do:
1. In case we are already terminating, bailout early
2. In case we are connected but not bound, disconnect and schedule
   a connection cleanup silently (don't reinstate)
3. In case we are connected and bound, disconnect and reinstate the connection

This rework fixes a bug that was detected against a mis-behaved
initiator which rejected our rdma_cm accept, in this stage the
isert_conn is no bound and reinstate caused a bogus dereference.

What's great about this is that we don't need the
post_recv_buf_count anymore, so get rid of it.

#1375303 — [PATCH 4.4 178/210] clk: rockchip: rk3368: fix cpuclk mux bit of big cpu-cluster

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiko Stuebner <heiko@sntech.de>

commit 535ebd428aeb07c3327947281306f2943f2c9faa upstream.

Both clusters have their mux bit in bit 7 of their respective register.
For whatever reason the big cluster currently lists bit 15 which is
definitly wrong.

#1375316 — [PATCH 4.4 037/210] x86/mm: TLB_REMOTE_SEND_IPI should count pages

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nadav Amit <namit@vmware.com>

commit 18c98243ddf05a1827ad2c359c5ac051101e7ff7 upstream.

TLB_REMOTE_SEND_IPI was recently introduced, but it counts bytes instead
of pages.  In addition, it does not report correctly the case in which
flush_tlb_page flushes a page.  Fix it to be consistent with other TLB
counters.

A regression was bisected to this commit:

https://bugzilla.kernel.org/show_bug.cgi?id=115321

So it's probably better to hold off on backporting this commit (and
possibly the corresponding amdgpu commit as well).

Why not just provide stable with the bugfix as well?  Being
bug-compatible is a big plus :)

regression.

FYI, the backport to 4.5 triggered another bug report:

Is it fixed in Linus's tree yet?  If so, great, let me know the git
