#1358380 — [PATCH 4.2.y-ckt 79/98] arm64: account for sparsemem section alignment when choosing vmemmap offset

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

commit 36e5cd6b897e17d03008f81e075625d8e43e52d0 upstream.

Commit dfd55ad85e4a ("arm64: vmemmap: use virtual projection of linear
region") fixed an issue where the struct page array would overflow into the
adjacent virtual memory region if system RAM was placed so high up in
physical memory that its addresses were not representable in the build time
configured virtual address size.

However, the fix failed to take into account that the vmemmap region needs
to be relatively aligned with respect to the sparsemem section size, so that
a sequence of page structs corresponding with a sparsemem section in the
linear region appears naturally aligned in the vmemmap region.

So round up vmemmap to sparsemem section size. Since this essentially moves
the projection of the linear region up in memory, also revert the reduction
of the size of the vmemmap region.

Fixes: dfd55ad85e4a ("arm64: vmemmap: use virtual projection of linear region")

#1358381 — [PATCH 4.2.y-ckt 61/98] drm/amdgpu: return from atombios_dp_get_dpcd only when error

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Arindam Nath <arindam.nath@amd.com>

commit 0b39c531cfa12dad54eac238c2e303b994df1ef7 upstream.

In amdgpu_connector_hotplug(), we need to start DP link
training only after we have received DPCD. The function
amdgpu_atombios_dp_get_dpcd() returns non-zero value only
when an error condition is met, otherwise returns zero.
So in case the function encounters an error, we need to
skip rest of the code and return from amdgpu_connector_hotplug()
immediately. Only when we are successfull in reading DPCD
pin, we should carry on with turning-on the monitor.

#1358382 — [PATCH 4.2.y-ckt 80/98] tracing: Fix check for cpu online when event is disabled

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

commit dc17147de328a74bbdee67c1bf37d2f1992de756 upstream.

Commit f37755490fe9b ("tracepoints: Do not trace when cpu is offline") added
a check to make sure that tracepoints only get called when the cpu is
online, as it uses rcu_read_lock_sched() for protection.

Commit 3a630178fd5f3 ("tracing: generate RCU warnings even when tracepoints
are disabled") added lockdep checks (including rcu checks) for events that
are not enabled to catch possible RCU issues that would only be triggered if
a trace event was enabled. Commit f37755490fe9b only stopped the warnings
when the trace event was enabled but did not prevent warnings if the trace
event was called when disabled.

To fix this, the cpu online check is moved to where the condition is added
to the trace event. This will place the cpu online check in all places that
it may be used now and in the future.

Fixes: f37755490fe9b ("tracepoints: Do not trace when cpu is offline")
Fixes: 3a630178fd5f3 ("tracing: generate RCU warnings even when tracepoints are disabled")

The DRC Mode like "AIF1DRC1 Mode" and EQ Mode like "AIF1.1 EQ Mode" in
wm8994 codec driver are enum ctls, while the current driver accesses

From: Vittorio Alfieri <vittorio88@gmail.com>

commit 3c4c615d70c8cbdc8ba8c79ed702640930652a79 upstream.

The Parrot NMEA GPS Flight Recorder is a USB composite device
consisting of hub, flash storage, and cp210x usb to serial chip.
It is an accessory to the mass-produced Parrot AR Drone 2.
The device emits standard NMEA messages which make the it compatible
with NMEA compatible software. It was tested using gpsd version 3.11-3
as an NMEA interpreter and using the official Parrot Flight Recorder.

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Takashi Iwai <tiwai@suse.de>

commit 741338f99f16dc24d2d01ac777b0798ae9d10a90 upstream.

snd_soc_dapm_dai_link_get() and _put() access the associated ctl
values as value.integer.value[].  However, this is an enum ctl, and it
has to be accessed via value.enumerated.item[].  The former is long
while the latter is unsigned int, so they don't align.

During DRAM initialization on certain ASpeed devices, an incorrect
bit (bit 10) was checked in the "SDRAM Bus Width Status" register
to determine DRAM width.

Query bit 6 instead in accordance with the Aspeed AST2050 datasheet v1.05.

From: Alex Deucher <alexander.deucher@amd.com>

commit eda1d1cf8d18383f19cd2b752f786120efa4768f upstream.

On CI, we need to see if the number of crtcs changes to determine
whether or not we need to upload the mclk table again.  In practice
we don't currently upload the mclk table again after the initial load.
The only reason you would would be to add new states, e.g., for
arbitrary mclk setting which is not currently supported.

#1358392 — [PATCH 4.2.y-ckt 42/98] use ->d_seq to get coherency between ->d_inode and ->d_flags

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Al Viro <viro@zeniv.linux.org.uk>

commit a528aca7f359f4b0b1d72ae406097e491a5ba9ea upstream.

Games with ordering and barriers are way too brittle.  Just
bump ->d_seq before and after updating ->d_inode and ->d_flags
type bits, so that verifying ->d_seq would guarantee they are
coherent.

#1358394 — [PATCH 4.2.y-ckt 56/98] parisc: Fix ptrace syscall number and return value modification

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Helge Deller <deller@gmx.de>

commit 98e8b6c9ac9d1b1e9d1122dfa6783d5d566bb8f7 upstream.

Mike Frysinger reported that his ptrace testcase showed strange
behaviour on parisc: It was not possible to avoid a syscall and the
return value of a syscall couldn't be changed.

To modify a syscall number, we were missing to save the new syscall
number to gr20 which is then picked up later in assembly again.

The effect that the return value couldn't be changed is a side-effect of
another bug in the assembly code. When a process is ptraced, userspace
expects each syscall to report entrance and exit of a syscall.  If a
syscall number was given which doesn't exist, we jumped to the normal
syscall exit code instead of informing userspace that the (non-existant)
syscall exits. This unexpected behaviour confuses userspace and thus the
bug was misinterpreted as if we can't change the return value.

This patch fixes both problems and was tested on 64bit kernel with
32bit userspace.

#1358396 — [PATCH 4.2.y-ckt 66/98] ovl: ignore lower entries when checking purity of non-directory entries

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Konstantin Khlebnikov <koct9i@gmail.com>

commit 45d11738969633ec07ca35d75d486bf2d8918df6 upstream.

After rename file dentry still holds reference to lower dentry from
previous location. This doesn't matter for data access because data comes
from upper dentry. But this stale lower dentry taints dentry at new
location and turns it into non-pure upper. Such file leaves visible
whiteout entry after remove in directory which shouldn't have whiteouts at
all.

Overlayfs already tracks pureness of file location in oe->opaque.  This
patch just uses that for detecting actual path type.

Comment from Vivek Goyal's patch:

Here are the details of the problem. Do following.

$ mkdir upper lower work merged upper/dir/
$ touch lower/test
$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=
work merged
$ mv merged/test merged/dir/
$ rm merged/dir/test
$ ls -l merged/dir/
/usr/bin/ls: cannot access merged/dir/test: No such file or directory
total 0
c????????? ? ? ? ?            ? test

Basic problem seems to be that once a file has been unlinked, a whiteout
has been left behind which was not needed and hence it becomes visible.

Whiteout is visible because parent dir is of not type MERGE, hence
od->is_real is set during ovl_dir_open(). And that means ovl_iterate()
passes on iterate handling directly to underlying fs. Underlying fs does
not know/filter whiteouts so it becomes visible to user.

Why did we leave a whiteout to begin with when we should not have.
ovl_do_remove() checks for OVL_TYPE_PURE_UPPER() and does not leave
whiteout if file is pure upper. In this case file is not found to be pure
upper hence whiteout is left.

So why file was not PURE_UPPER in this case? I think because dentry is
still carrying some leftover state which was valid before rename. For
example, od->numlower was set to 1 as it was a lower file. After rename,
this state is not valid anymore as there is no such file in lower.

commit 17e2df4613be57d0fab68df749f6b8114e453152 upstream.

Plantronics DA45 does not support reading the sample rate which leads
to many lines of "cannot get freq at ep 0x4" and "cannot get freq at
ep 0x84". This patch adds the USB ID of the DA45 to quirks.c and
avoids those error messages.

#1358398 — [PATCH 4.2.y-ckt 72/98] ARM: dts: dra7: do not gate cpsw clock due to errata i877

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Mugunthan V N <mugunthanvnm@ti.com>

commit 0f514e690740e54815441a87708c3326f8aa8709 upstream.

Errata id: i877

Description:
------------
The RGMII 1000 Mbps Transmit timing is based on the output clock
(rgmiin_txc) being driven relative to the rising edge of an internal
clock and the output control/data (rgmiin_txctl/txd) being driven relative
to the falling edge of an internal clock source. If the internal clock
source is allowed to be static low (i.e., disabled) for an extended period
of time then when the clock is actually enabled the timing delta between
the rising edge and falling edge can change over the lifetime of the
device. This can result in the device switching characteristics degrading
over time, and eventually failing to meet the Data Manual Delay Time/Skew
specs.
To maintain RGMII 1000 Mbps IO Timings, SW should minimize the
duration that the Ethernet internal clock source is disabled. Note that
the device reset state for the Ethernet clock is "disabled".
Other RGMII modes (10 Mbps, 100Mbps) are not affected

Workaround:
-----------
If the SoC Ethernet interface(s) are used in RGMII mode at 1000 Mbps,
SW should minimize the time the Ethernet internal clock source is disabled
to a maximum of 200 hours in a device life cycle. This is done by enabling
the clock as early as possible in IPL (QNX) or SPL/u-boot (Linux/Android)
by setting the register CM_GMAC_CLKSTCTRL[1:0]CLKTRCTRL = 0x2:SW_WKUP.

So, do not allow to gate the cpsw clocks using ti,no-idle property in
cpsw node assuming 1000 Mbps is being used all the time. If someone does
not need 1000 Mbps and wants to gate clocks to cpsw, this property needs
to be deleted in their respective board files.
