2012-05-12sparc32: Un-btfixup {pte,pmd,pgd}_clear().David S. Miller
Also we can remove BTFIXUPCALL_SWAPO0G0 as that is no longer used. This was rather amusing, we were setting the btfixup vectors based upon cpu type but all to the same exact generic srmmu routines. Furthermore, we were inconsistently marking the fixup as either BTFIXUPCALL_SWAPO0G0 or BTFIXUPCALL_NORM. What a mess, glad we could untangle this stuff. Signed-off-by: David S.

2012-05-12usb/net: rndis: move and namespace PnP definesLinus Walleij
This moves the PnP OID definitions to the RNDIS_* namespace and puts them in the next falling slot in the list. Oh, the comment above the PnP defines was referring to some obsolete or out-of-tree driver so removed it, and removed my own comments telling where each header segment came from as well, we have moved everything around by this point anyway.

2012-05-12usb/net: rndis: merge media type definitionsLinus Walleij
Let's have a unified table of RNDIS media. We used to have a similar table with NDIS_* prefix from the gadget driver, but since we're only using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows- internal network drivers so what do we care) let's prefix everything with RNDIS. Some of the definitions were conflicting, in one of the defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took the majority vote. Two definition of medium 0x09 calls it "wireless WAN" but one vote for "wireless LAN" but in this case I am sticking with the minority, "Wide Area Network" does not make much sense in this case as far as I can tell. NOTE: latin singular and plural is so screwed up in these defines that it makes my eyes bleed. But I will not attempt to submit a patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED is most probably (erroneously) referring to a singular, unless it can return an array of connected media. I suspect these erroneous plurals are used in documentation and such so I don't want to mess around with things for no functional change.

2012-05-12usb/net: rndis: merge duplicate 802_* OIDsLinus Walleij

2012-05-12usb/net: rndis: eliminate first set of duplicate OIDsLinus Walleij
The RNDIS protocol contains a vast number of Object ID:s (OIDs). The current definitions had multiple definitions of these ID:s, let's use the nicely RNDIS_*-prefixed defines from the HyperV implementation, rename everywhere they're used, and copy+rename the few that were missing from this list of objects.

2012-05-12usb/net: rndis: remove ambigous status codesLinus Walleij
The RNDIS status codes are redefined with much stranged ifdeffery and only one of these codes was used in the hyperv driver, and there it is very clearly referring to the RNDIS variant, not some other status. So clarify this by explictly using the RNDIS_* prefixed status code in the hyperv drivera and delete the duplicate defines.

2012-05-12usb/net: rndis: break out <linux/rndis.h> definesLinus Walleij
As a first step to consolidate the RNDIS implementations, break out a common file with all the #defines and move it to <linux/rndis.h>. This also deletes the immediate duplicated defines in the <linux/rndis.h> file that yields a lot of compilation warnings.

2012-05-12usb/net: rndis: inline the cpu_to_le32() macroLinus Walleij
The header file <linux/usb/rndis_host.h> used a number of #defines that included the cpu_to_le32() macro to assure the result will be in LE endianness. Inlining this into the code instead of using it in the code definitions yields consolidation opportunities later on as you will see in the following patches. The individual drivers also used local defines - all are switched over to the pattern of doing the conversion at the call sites instead.

2012-05-12ARM: 7417/1: vfp: ensure preemption is disabled when enabling VFP accessWill Deacon
The vfp_enable function enables access to the VFP co-processor register space (cp10 and cp11) on the current CPU and must be called with preemption disabled. Unfortunately, the vfp_init late initcall does not disable preemption and can lead to an oops during boot if thread migration occurs at the wrong time and we end up attempting to access the FPSID on a CPU with VFP access disabled. This patch fixes the initcall to call vfp_enable from a non-preemptible context on each CPU and adds a BUG_ON(preemptible) to ensure that any similar problems are easily spotted in the future.

2012-05-12Merge tag 'regmap-3.4' into regmap-strideMark Brown
regmap: Last minute bug fix for 3.4 This is a last minute bug fix that was only just noticed since the code path that's being exercised here is one that is fairly rarely used. The changelog for the change itself is extremely clear and the code itself is obvious to inspection so should be pretty safe.

2012-05-12regulator: core: Allow regulators to provide a voltage to selector mappingMark Brown
In order to allow more drivers to factor things out into data allow drivers to provide a mapping function to convert voltages into selectors. This allows any driver to use set_voltage_sel(). The existing mapping based on iterating over list_voltage() is provided as an operation which can be assigned to the new map_voltage() function though for ease of transition it is treated as the default.
