2016-05-28MIPS: Simplify DSP instruction encoding macrosJames Hogan
Simplify the DSP instruction wrapper macros which use explicit encodings for microMIPS and normal MIPS by using the new encoding macros and removing duplication. To me this makes it easier to read since it is much shorter, but it also ensures .insn is used, preventing objdump disassembling the microMIPS code as normal MIPS.

2016-05-28MIPS: Add missing tlbinvf/XPA microMIPS encodingsJames Hogan
Hardcoded MIPS instruction encodings are provided for tlbinvf, mfhc0 & mthc0 instructions, but microMIPS encodings are missing. I doubt any microMIPS cores exist at present which support these instructions, but the microMIPS encodings exist, and microMIPS cores may support them in the future. Add the missing microMIPS encodings using the new macros.

2016-05-28MIPS: Fix little endian microMIPS MSA encodingsJames Hogan
When the toolchain doesn't support MSA we encode MSA instructions explicitly in assembly. Unfortunately we use .word for both MIPS and microMIPS encodings which is wrong, since 32-bit microMIPS instructions are made up from a pair of halfwords. - The most significant halfword always comes first, so for little endian builds the halves will be emitted in the wrong order. - 32-bit alignment isn't guaranteed, so the assembler may insert a 16-bit nop instruction to pad the instruction stream to a 32-bit boundary. Use the new instruction encoding macros to encode microMIPS MSA instructions correctly. Fixes: d96cc3d1ec5d ("MIPS: Add microMIPS MSA support.")

2016-05-28MIPS: Add missing VZ accessor microMIPS encodingsJames Hogan
Toolchains may be used which support microMIPS but not VZ instructions (i.e. binutis 2.22 & 2.23), so extend the explicitly encoded versions of the guest COP0 register & guest TLB access macros to support microMIPS encodings too, using the new macros. This prevents non-microMIPS instructions being executed in microMIPS mode during CPU probe on cores supporting VZ (e.g. M5150), which cause reserved instruction exceptions early during boot.

2016-05-28MIPS: Add inline asm encoding helpersJames Hogan
To allow simplification of macros which use inline assembly to explicitly encode instructions, add a few simple abstractions to mipsregs.h which expand to specific microMIPS or normal MIPS encodings depending on what type of kernel is being built: _ASM_INSN_IF_MIPS(_enc) : Emit a 32bit MIPS instruction if microMIPS is not enabled. _ASM_INSN32_IF_MM(_enc) : Emit a 32bit microMIPS instruction if enabled. _ASM_INSN16_IF_MM(_enc) : Emit a 16bit microMIPS instruction if enabled. The macros can be used one after another since the MIPS / microMIPS macros are mutually exclusive, for example: __asm__ __volatile__( ".set push\n\t" ".set noat\n\t" "# mfgc0 $1, $%1, %2\n\t" _ASM_INSN_IF_MIPS(0x40610000 | %1 << 11 | %2) _ASM_INSN32_IF_MM(0x002004fc | %1 << 16 | %2 << 11) "move %0, $1\n\t" ".set pop" : "=r" (__res) : "i" (source), "i" (sel)); Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13310/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2016-05-27nfs: fix anonymous member initializer build failure with older compilersLinus Torvalds
Older versions of gcc don't understand named initializers inside a anonymous structure or union member. It can be worked around by adding the bracin gin the initializer for the anonymous member. Without this, gcc 4.4.4 will fail the build with CC fs/nfs/nfs4state.o fs/nfs/nfs4state.c:69: error: unknown field ‘data’ specified in initializer fs/nfs/nfs4state.c:69: warning: missing braces around initializer fs/nfs/nfs4state.c:69: warning: (near initialization for ‘zero_stateid.<anonymous>.data’) make[2]: *** [fs/nfs/nfs4state.o] Error 1 introduced in commit 93b717fd81bf ("NFSv4: Label stateids with the type") Reported-and-tested-by: Boris Ostrovsky <boris.ostrovsky@oracle.com> Cc: Anna Schumaker <Anna.Schumaker@netapp.com> Cc: Trond Myklebust <trond.myklebust@primarydata.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2016-05-27switch ->setxattr() to passing dentry and inode separatelyAl Viro
smack ->d_instantiate() uses ->setxattr(), so to be able to call it before we'd hashed the new dentry and attached it to inode, we need ->setxattr() instances getting the inode as an explicit argument rather than obtaining it from dentry. Similar change for ->getxattr() had been done in commit ce23e64. Unlike ->getxattr() (which is used by both selinux and smack instances of ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately it got missed back then.

2016-05-27Input: pwm-beeper - fix - scheduling while atomicManfred Schlaegl
Pwm config may sleep so defer it using a worker. On a Freescale i.MX53 based board we ran into "BUG: scheduling while atomic" because input_inject_event locks interrupts, but imx_pwm_config_v2 sleeps. Tested on Freescale i.MX53 SoC with 4.6.0.
