It looks like this patch is not included in the 4.14 stable series. Can this patch be applied? I applied it myself and it applies cleanly, but I have no way to test it.

Ich bin verheiratet mit Herrn Robert Hermann, der im Jahr 2002 mit unserer Botschaft in Deutschland gearbeitet hat und auch für 16 Jahre in einer Botschaft in London gearbeitet hat, bevor er starb. Wir waren 25 Jahre ohne Kind verheiratet, bevor er nach kurzer Krankheit starb. Seit seinem Tod entschied ich mich aufgrund meines religiösen Glaubens nicht wieder zu heiraten. Als mein verstorbener Mann noch am Leben war, hinterlegte er die Summe von $ 10.500.000,00 (Zehn Millionen Fünfhunderttausend US-Dollar) bei einer Bank hier in Amerika. Zurzeit befindet sich dieses Geld noch in der Obhut der Bank. Kürzlich sagte mir mein Doktor, dass ich wegen meiner Krebserkrankung für die nächsten vier Monate nicht durchhalten würde. Nachdem ich meinen Zustand gekannt habe, habe ich beschlossen, dieses Geld an Kirchen, Organisationen oder gute Menschen zu spenden, die dieses Geld nutzen werden, so wie ich es hier unterrichten werde. Ich möchte, dass Sie dieses Geld für Kirchen, Wohltätigkeitsorganisationen, Waisenhäuser, Witwen und andere Bedürftige verwenden. Ich habe diese Entscheidung getroffen, weil ich kein Kind habe, das dieses Geld erbt. Außerdem sind die Verwandten meines Mannes mir nicht nahe, da ich ein Krebsproblem habe und es ihr Wunsch war, mich tot zu sehen, um seinen Reichtum zu erben, da wir kein Kind haben. Diese Leute sind dieses Erbe nicht wert. Aus diesem Grund nehme ich die Entscheidung, dich zu kontaktieren und spende diesen Fond an dich, damit du ihn für die Wohltätigkeitsarbeit verwenden kannst. Ich möchte, dass Sie 30% des Gesamtbetrags für sich selbst übernehmen. Wenn Sie sicher sind, dass Sie diesen Fonds in Übereinstimmung mit den Anweisungen verwenden, Sobald ich Ihre Antwort erhalten habe, werde ich Ihnen den Kontakt der Bank hier in den Vereinigten Staaten von Amerika geben, wo dieses Geld hinterlegt ist. Ich werde der Bank auch ein Bewilligungsschreiben ausstellen, das Ihnen den gegenwärtigen Begünstigten dieses Geldes beweisen wird. Ich möchte auch, dass du mich immer in deine Gebete bringst.

Allow sequential->interlaced interweaving but with top/bottom
lines swapped to the output buffer.
This can be accomplished by adding one line length to IDMAC output
channel address, with a negative line length for the interlace offset.
This is to allow the seq-bt -> interlaced-bt transformation, where
bottom lines are still dominant (older in time) but with top lines
first in the interweaved output buffer.
With this support, the CSI can now allow seq-bt at its source pads,
e.g. the following transformations are allowed in CSI from sink to
source:
seq-tb -> seq-bt
seq-bt -> seq-bt
alternate -> seq-bt

We have to store this instead of using vdev->fmt.fmt.bytesperline
because this potentially is the pre-rotation stride instead?
interweave_offset was used by prp_vb2_buf_done() below, but in fact
that function is passed the non-rotation IDMAC channel (priv->out_ch)
_only_ if rotation is not enabled, so it is actually safe to use
vdev->fmt.fmt.bytesperline for the interweave offset in
prp_vb2_buf_done().
So I've gotten rid of interweave_offset in both imx-ic-prpencvf.c and
imx-media-csi.c, and replaced with a boolean interweave_swap as you
suggested. I agree it is much cleaner.

This doesn't seem necessary. Since there is no rotation here, the offset
is just vdev->fmt.fmt.pix.bytesperline if interweave_swap is enabled.
Maybe turn this into a bool interweave_swap?
Agreed.

I think this is a bit convoluted. Instead of initializing std, then
possibly changing it, and then comparing to the inital value, and then
checking it again to determine the new height, why not just:
if (width == 720 && height == 480) {
std = V4L2_STD_NTSC;
height = 525;
} else if (width == 720 && height == 576) {

height = 625;

?
Yes that was a bit convoluted, fixed.

- if (is_parallel_bus(>upstream_ep) && incc->cycles) {

If the input format width passed to ipu_csi_init_interface is not
multiplied by the number of cycles per pixel anymore, width in the
CSI_SENS_FRM_SIZE register will be set to the unmultiplied value from
infmt.
This breaks 779680e2e793 ("media: imx: add support for RGB565_2X8 on

Oops, that was a mistake, thanks for catching, fixed.

Great, thanks for sorting this out and coming back with a V2 so quickly.
Applied to the togreg branch of iio.git which is initially pushed out as
testing for the autobuilders to play with it.
We are late in the current kernel cycle, so this will probably not go
upstream until the merge window after the one that will open in a few
weeks time.
Thanks,

[PATCH 4.4 028/113] staging: android: ashmem: Fix mmap size validation
4.4-stable review patch. If anyone has any objections, please let me know.
--
From: Alistair Strachan
[ Upstream commit 8632c614565d0c5fdde527889601c018e97b6384 ]
The ashmem driver did not check that the size/offset of the vma passed
to its .mmap() function was not larger than the ashmem object being
mapped. This could cause mmap() to succeed, even though accessing parts
of the mapping would later fail with a segmentation fault.
Ensure an error is returned by the ashmem_mmap() function if the vma
size is larger than the ashmem object size. This enables safer handling
of the problem in userspace.

Thanks, Alexey The alignment option was removed from the allocation API before because the most common heap (system heap) didn't support it and it was causing more confusion.

It seems like what you're saying is that, under certain conditions (which arguably would be bugs in the core Linux timing code), actually calling ktime_get_boot_ns() could be non-monotonic with respect to the kvmclock timing. But get_kvmclock_ns() isn't used for VM timing as such -- it's used for the IOCTL interfaces for updating the time offset. So can you explain how my patch is incorrect? --Andy ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel

It's writing to the wrong structure member.
The function is used on the V4L2 control V4L2_CID_COLORFX_CBCR, which
is defined as:
V4L2_CID_COLORFX_CBCR (integer)
Determines the Cb and Cr coefficients for V4L2_COLORFX_SET_CBCR color
effect. Bits [7:0] of the supplied 32 bit value are interpreted as Cr
component, bits [15:8] as Cb component and bits [31:16] must be zero.
ctrl->val should therefore be setting dev->colourfx.u and
dev->colourfx.v with those masks. dev->colourfx.enable field should
have been set when going through ctrl_set_image_effect for contol
V4L2_CID_COLORFX set to V4L2_COLORFX_SET_CBCR.
I've confirmed with qv4l2 that that is what is wrong. That's only been
lurking there for almost 5 years - shows how often these weirder
effects get used.
I don't mind whether Colin's patch gets merged and then fixed up, or
drop Colin's patch and apply the correct logic via a new patch.

Want to - not really. Ought to - I guess so.
I've got a bunch of checkpatch and other fixes to come too, so once
I've got a mainline kernel build back up and running I'll roll them
all up and blitz the list.

as long as the current behavior is correct, i'm okay with this patch.
But the byte masking looks suspicious, so i hope Dave can clarify that.

"In the non-fallback case, a bunch of gnarly arithmetic is done: a
hopefully matched pair of (TSC, boot time) is read, then all locks
are dropped, then the TSC frequency is read, a branch new multiplier
and shift is read, and the result is turned into a time.
This seems quite racy to me. Because locks are not held, I don't
see what keeps TSC frequency used in sync with the master clock
data."
If tsc_khz changes, the host TSC clocksource will not be used, which
disables masterclock:
if ((val == CPUFREQ_PRECHANGE && freq->old < freq->new) ||
(val == CPUFREQ_POSTCHANGE && freq->old >
freq->new)) {
*lpj = cpufreq_scale(loops_per_jiffy_ref, ref_freq,
freq->new);
tsc_khz = cpufreq_scale(tsc_khz_ref, ref_freq,
freq->new);
if (!(freq->flags & CPUFREQ_CONST_LOOPS))
mark_tsc_unstable("cpufreq changes");
In which case it ends up in:
- spin_lock(>pvclock_gtod_sync_lock);
- if (!ka->use_master_clock) {
- spin_unlock(>pvclock_gtod_sync_lock);
- return ktime_get_boot_ns() + ka->kvmclock_offset;
- }
masterclock -> non masterclock transition sets
a REQUEST bit on each vCPU, so as to invalidate any previous
clock reads.
static void kvm_gen_update_masterclock(struct kvm *kvm)
{
#ifdef CONFIG_X86_64

[PATCH] staging: bcm2835-camera: remove extraneous setting of dev->colourfx.enable
From: Colin Ian King
Currently dev->colourfx.enable is being set twice, hence the first
occurrance is redundant and can be removed, so remove it. This minor
issue was introduced by commit 7b3ad5abf027 ("staging: Import the
BCM2835 MMAL-based V4L2 camera driver.").

Please refer to https://github.com/lz4/lz4/issues/566 for more details the reason why EROFS uses the different implementation rather than the current lib/lz4/ code in the kernel today (it will be changed in the next Linux version if the updated code works fine.)

This exact fix was applied to linux-next some days ago:
commit ea0b2d429bd82ec152d286a0c026ebcaa4154ccc
Make sure you are working from linux-next rather than from mainline.
See this link: https://www.kernel.org/doc/man-pages/linux-next.html

Had you had the time to look at the issue? I have looked at the issue, but not manage to cook some patches for it. However, it's on my top of my TODO list for mmc. No promises, but perhaps and hopefully I manage to get something posted during the coming release cycle. I would be interested in a ESP8089 driver in mainline and that's why I want to pick up this discussion. What is the current status of the "mmc_reprobe_device" implementation, that Hans was explaining and Ulf wanted to provide some months ago? Ulf did eventually write a new way to deal with this and then Quentin did manage to get the esp8089 driver to work with it, the new function to use for this is added by this commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/mmc/core?id=1433269c4d2461be1f36db5dbb453976b38996ff I'm not sure what the status of upstreaming the ep8089 driver is now that we've this in place. Quentin, do you have a version of the esp8089 driver somewhere which will work correctly with the new mmc_sw_reset() function? Also what is the status of adding this driver to say staging? IIRC, we tried to get it into staging, and we got told that it was too nice for staging at this point. So we're basically stuck somewhere between staging and !staging, with the driver being too nice for the former, and not nice enough for the latter :) Ok, and is there someone willing to continue upstreaming the driver? Maybe someone can rebase and resend the latest approach? After all it looks like a lot of work has already been done.

This is a common practice for debugging.

[v3, 4/6] net: dpaa2: rename rtc as ptp in dpaa2-ptp driver
In dpaa2-ptp driver, it's odd to use rtc in names of
some functions and structures except these dprtc APIs.
This patch is to use ptp instead of rtc in names.
