2015-10-09dm snapshot: add new persistent store option to support overflowMike Snitzer
Commit 76c44f6d80 introduced the possibly for "Overflow" to be reported by the snapshot device's status. Older userspace (e.g. lvm2) does not handle the "Overflow" status response. Fix this incompatibility by requiring newer userspace code, that can cope with "Overflow", request the persistent store with overflow support by using "PO" (Persistent with Overflow) for the snapshot store type.

This patch adds a compatible string to support for R-Car H3. Since the HS-USB controller of R-Car H3 is almost the same specification with R-Car Gen2 (these have 16 pipes and usb-dmac), this patch sets the "type" of renesas_usbhs_driver_param to USBHS_TYPE_RCAR_GEN2.

However, to fix these warnings, it's possible to define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to "long long" on ppc64, too.

2015-09-25MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too oldDavid Howells
The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file since that allows the target X.509 certificate to be specified by subjectKeyId rather than by issuer + serialNumber. However, older versions of the OpenSSL crypto library (such as may be found in CentOS 5.11) don't support CMS. Assume everything prior to OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case. Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so give an error from the sign-file script if the caller requests anything other than SHA1. The compiler gives the following error with an OpenSSL crypto library that's too old: HOSTCC scripts/sign-file scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory #include <openssl/cms.h> Reported-by: Vinson Lee <vlee@twopensource.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: David Woodhouse <David.Woodhouse@intel.com>

The idle-states bindings mandate that the entry-method string in the idle-states node must be "psci" for ARM v8 64-bit systems, but the examples in the bindings report a wrong entry-method string. Owing to this typo, some dts in the kernel wrongly defined the entry-method property, since they likely cut and pasted the example definition without paying attention to the bindings definitions. This patch fixes the typo in the DT idle states bindings examples and respective dts in the kernel so that the bindings and related dts files are made compliant.

The gpiolib supports parsing DT properties of the form <name>-gpio but it was only added for compatibility with older DT bindings that got it wrong and should not be used in newer bindings. The commit that added support for this was: dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names") but didn't update the documentation to explain this so it's been a source of confusion.

There are air quality sensors that report data back in parts per million of VOC (Volatile Organic Compounds) which are usually indexed from CO2 or another common pollutant. This patchset adds an IIO_CONCENTRATION type that returns a percentage of substance because no other channels types fit this use case. Modifiers for IIO_MOD_CO2 and IIO_MOD_VOC gas types are defined.

2015-09-17devicetree: bindings: Extend the bma180 bindings with bma250 infoHans de Goede
The bma180 / bma250 accelerometers share a driver (at least under Linux), so it makes sense to also have their bindings info in a single .txt. This commit extends the bma180 bindings with bma250 bindings, specifically it specifies how the 2 seperate interrupts the bma250 has must be listed in devicetree. The existing bma180 driver is already fully compatible with the specified bindings. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rob Herring <robh@kernel.org>
