2015-08-11mfd: arizona: Update several pdata members to unsignedCharles Keepax1-6/+6
Device tree and ACPI primarily deal with unsigned ints, many of the pdata members in the Arizona driver are signed ints but are only ever assigned positive values. Changing these pdata fields to unsigned ints avoids us having to choose between overly verbose code and Sparse warnings.

2015-08-11mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform dataMatt Fleming2-6/+19
Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across the SMBus, unlike previous generations of PCH/ICH where it was on the LPC bus. Because it's on the SMBus, it doesn't make sense to pass around a 'struct lpc_ich_info', and leaking the type of bus into the iTCO watchdog driver is kind of backwards anyway. This change introduces a new 'struct itco_wdt_platform_data' for use inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint code, which neatly avoids having to include lpc_ich headers in the i801 i2c driver. This change is overdue because lpc_ich_info has already found its way into other TCO watchdog users, notably the intel_pmc_ipc driver where the watchdog actually isn't on the LPC bus as far as I can see. A simple translation layer is provided for converting from the existing 'struct lpc_ich_info' inside the lpc_ich mfd driver.

This patch replaces the zone id which is pushed down into functions with the actual zone object. It's a bigger one-time change, but needed for later on extending zones with a direction parameter, and thus decoupling this additional information from all call-sites. No functional changes in this patch. The default zone becomes a global const object, namely nf_ct_zone_dflt and will be returned directly in various cases, one being, when there's f.e. no zoning support.

2015-08-10mm: enhance region_is_ram() to region_intersects()Dan Williams1-1/+8
region_is_ram() is used to prevent the establishment of aliased mappings to physical "System RAM" with incompatible cache settings. However, it uses "-1" to indicate both "unknown" memory ranges (ranges not described by platform firmware) and "mixed" ranges (where the parameters describe a range that partially overlaps "System RAM"). Fix this up by explicitly tracking the "unknown" vs "mixed" resource cases and returning REGION_INTERSECTS, REGION_MIXED, or REGION_DISJOINT. This re-write also adds support for detecting when the requested region completely eclipses all of a resource. Note, the implementation treats overlaps between "unknown" and the requested memory type as REGION_INTERSECTS. Finally, other memory types can be passed in by name, for now the only usage "System RAM". Suggested-by: Luis R.

2015-08-10net: add explicit logging and stat for neighbour table overflowRick Jones2-0/+2
Add an explicit neighbour table overflow message (ratelimited) and statistic to make diagnosing neighbour table overflows tractable in the wild. Diagnosing a neighbour table overflow can be quite difficult in the wild because there is no explicit dmesg logged. Callers to neighbour code seem to use net_dbg_ratelimit when the neighbour call fails which means the "base message" is not emitted and the callback suppressed messages from the ratelimiting can end-up juxtaposed with unrelated messages. Further, a forced garbage collection will increment a stat on each call whether it was successful in freeing-up a table entry or not, so that statistic is only a hint. So, add a net_info_ratelimited message and explicit statistic to the neighbour code. Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-10svcrdma: Change maximum server payload back to RPCSVC_MAXPAYLOADChuck Lever1-7/+2
Both commit 0380a3f375 ("svcrdma: Add a separate "max data segs" macro for svcrdma") and commit 7e5be28827bf ("svcrdma: advertise the correct max payload") are incorrect. This commit reverts both changes, restoring the server's maximum payload size to 1MB. Commit 7e5be28827bf based the server's maximum payload on the _client's_ RPCRDMA_MAX_DATA_SEGS value. That was wrong. Commit 0380a3f375 tried to fix this so that the client maximum payload size could be raised without affecting the server, but managed to confuse matters more on the server side. More importantly, limiting the advertised maximum payload size was meant to be a workaround, not the actual fix. We need to revisit https://bugzilla.linux-nfs.org/show_bug.cgi?id=270 A Linux client on a platform with 64KB pages can overrun and crash an x86_64 NFS/RDMA server when the r/wsize is 1MB.

Currently, when trying to connect to already paired device that just rotated its RPA MAC address, old address would be used and connection would fail. In order to fix that, kernel must scan and receive advertisement with fresh RPA before connecting. This patch adds some fields to hci_conn_params, in preparation to new connect procedure. explicit_connect will be used to override any current auto_connect action, and connect to device when ad is received. HCI_AUTO_CONN_EXPLICIT was added to auto_connect enum. When this value will be used, explicit connect is the only action, and params can be removed after successful connection. HCI_CONN_SCANNING is added to hci_conn flags. When it's set, connect is scan phase. It gets cleared when advertisement is received, and HCI_OP_LE_CREATE_CONN is sent.

2015-08-08iio: Add inverse unit conversion macrosLars-Peter Clausen1-0/+17
Add inverse unit conversion macro to convert from standard IIO units to units that might be used by some devices. Those are useful in combination with scale factors that are specified as IIO_VAL_FRACTIONAL. Typically the denominator for those specifications will contain the maximum raw value the sensor will generate and the numerator the value it maps to in a specific unit. Sometimes datasheets specify those in different units than the standard IIO units (e.g. degree/s instead of rad/s) and so we need to do a unit conversion. From a mathematical point of view it does not make a difference whether we apply the unit conversion to the numerator or the inverse unit conversion to the denominator since (x / y) / z = x / (y * z). But as the denominator is typically a larger value and we are rounding both the numerator and denominator to integer values using the later method gives us a better precision (E.g. the relative error is smaller if we round 8000.3 to 8000 rather than rounding 8.3 to 8). This is where in inverse unit conversion macros will be used. Marked for stable as used by some upcoming fixes.
