2014-05-18sparc64: fix sparse warning in traps_64.cSam Ravnborg
Fix following warning: traps_64.c:2384:6: error: symbol 'die_if_kernel' redeclared with different type (originally declared at include/asm/bug.h:23) - different modifiers Add proper __noreturn to the implementation to fix this Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-18sparc: drop use of extern for prototypes in arch/sparc/*Sam Ravnborg
Drop the remaining uses of extern for prototypes in .h files in the sparc specific part of the kernel tree. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-18sparc: drop use of extern for prototypes in arch/sparc/include/asmSam Ravnborg
Drop extern for all prototypes and adjust alignment of parameters as required after the removal. In a few rare cases adjust linelength to conform to maximum 80 chars, and likewise in a few rare cases adjust alignment of parameters to static functions.

2014-05-18sparc32: drop tadpole specific codeSam Ravnborg
tadpole.c assigned cpu_pwr_save based on the current configuration. The rest of the tadpole.c file was only used if cpu_pwr_save was dereferenced. But this variable was never dereferenced - and I went back to a 2.6.12 kernel to check (from June 2005) - and not even then was it used. Drop this code as it has not been in use for ~10 years.

Function mlx4_en_set_channels() stops running ports before performing the requested action. In that case local variable 'port_up' is set so that the port is restarted at the end of the function, however, in case the port was not stopped, variable 'port_up' is left uninitialized and the behaviour is undetermined.

2014-05-19irqchip: gic: Use mask field in GICC_IARHaojian Zhuang
Bit[9:0] is interrupt ID field in GICC_IAR. Bit[12:10] is CPU ID field, and others are reserved. So we should use GICC_IAR_INT_ID_MASK to get interrupt ID.

2014-05-19ethtool: Name the 'no change' value for setting RSS hash key but not indir tableBen Hutchings
We usually allocate special values of u32 fields starting from the top down, so also change the value to 0xffffffff. As these operations haven't been included in a stable release yet, it's not too late to change. Signed-off-by: Ben Hutchings <ben@decadent.org.uk>

2014-05-19virtio-rng: fixes for device registration/unregistrationSasha Levin
There are several fixes in this patch (mostly because it's hard splitting them up): - Revert the name field in struct hwrng back to 'const'. Also, don't do an extra kmalloc for the name - just wasteful. - Deal with allocation failures properly. - Use IDA to allocate device number instead of brute forcing one.
