- If the patch covers files in net/ or drivers/net please follow netdev stable
submission guidelines as described in
Documentation/networking/netdev-FAQ.txt
- - Send the patch, after verifying that it follows the above rules, to
- stable@vger.kernel.org. You must note the upstream commit ID in the
- changelog of your submission, as well as the kernel version you wish
- it to be applied to.
- - To have the patch automatically included in the stable tree, add the tag
+ - Security patches should not be handled (solely) by the -stable review
+ process but should follow the procedures in Documentation/SecurityBugs.
+
+For all other submissions, choose one of the following procedures:
+
+ --- Option 1 ---
+
+ To have the patch automatically included in the stable tree, add the tag
Cc: stable@vger.kernel.org
in the sign-off area. Once the patch is merged it will be applied to
the stable tree without anything else needing to be done by the author
or subsystem maintainer.
- - If the patch requires other patches as prerequisites which can be
- cherry-picked, then this can be specified in the following format in
- the sign-off area:
+
+ --- Option 2 ---
+
+ After the patch has been merged to Linus' tree, send an email to
+ stable@vger.kernel.org containing the subject of the patch, the commit ID,
+ why you think it should be applied, and what kernel version you wish it to
+ be applied to.
+
+ --- Option 3 ---
+
+ Send the patch, after verifying that it follows the above rules, to
+ stable@vger.kernel.org. You must note the upstream commit ID in the
+ changelog of your submission, as well as the kernel version you wish
+ it to be applied to.
+
+Option 1 is probably the easiest and most common. Options 2 and 3 are more
+useful if the patch isn't deemed worthy at the time it is applied to a public
+git tree (for instance, because it deserves more regression testing first).
+Option 3 is especially useful if the patch needs some special handling to apply
+to an older kernel (e.g., if API's have changed in the meantime).
+
+Additionally, some patches submitted via Option 1 may have additional patch
+prerequisites which can be cherry-picked. This can be specified in the following
+format in the sign-off area:
Cc: <stable@vger.kernel.org> # 3.3.x: a1f84a3: sched: Check for idle
Cc: <stable@vger.kernel.org> # 3.3.x: 1b9508f: sched: Rate-limit newidle
git cherry-pick fd21073
git cherry-pick <this commit>
+Following the submission:
+
- The sender will receive an ACK when the patch has been accepted into the
queue, or a NAK if the patch is rejected. This response might take a few
days, according to the developer's schedules.
- If accepted, the patch will be added to the -stable queue, for review by
other developers and by the relevant subsystem maintainer.
- - Security patches should not be sent to this alias, but instead to the
- documented security@kernel.org address.

+
+ Copyright (C) 2014 Linutronix GmbH
+ Author: John Ogness <john.ogness@linutronix.de>
+
+ This driver provides UIO access to memory of a peripheral connected
+ to the Freescale enhanced local bus controller (eLBC) interface
+ using the general purpose chip-select mode (GPCM).
+
+ Here is an example of the device tree entries:
+
+ localbus@ffe05000 {
+ ranges = <0x2 0x0 0x0 0xff810000 0x10000>;
+
+ dpm@2,0 {
+ compatible = "fsl,elbc-gpcm-uio";
+ reg = <0x2 0x0 0x10000>;
+ elbc-gpcm-br = <0xff810800>;
+ elbc-gpcm-or = <0xffff09f7>;
+ interrupt-parent = <&mpic>;
+ interrupts = <4 1>;
+ device_type = "netx5152";
+ uio_name = "netx_custom";
+ netx5152,init-win0-offset = <0x0>;
+ };
+ };
+
+ Only the entries reg (to identify bank) and elbc-gpcm-* (initial BR/OR
+ values) are required. The entries interrupt*, device_type, and uio_name
+ are optional (as well as any type-specific options such as
+ netx5152,init-win0-offset). As long as no interrupt handler is needed,
+ this driver can be used without any type-specific implementation.
+
+ The netx5152 type has been tested to work with the netX 51/52 hardware
+ from Hilscher using the Hilscher userspace netX stack.
+
+ The netx5152 type should serve as a model to add new type-specific
+ devices as needed.
