2014-07-30MIPS: SB1: Check optional compilation flags one by oneMaciej W. Rozycki1-1/+3
This fixes a regression caused by commit bb6c0bd3fdb67c8a1fceea1d4700b9ee593309f9 [MIPS: SB1: Fix excessive kernel warnings.], that makes `-march=r5000' selected for compilation flags rather than supposed `-march=sb1' with compilers that do not support the ASE selection flags introduced with that change. For example GCC 4.1.2 supports `-mips3d'/`-mno-mips3d' (and obviously `-march=sb1'), however it does not support `-mdmx'/`-mno-mdmx'. As a result the whole selection of flags fails and compilation resorts to using `-march=r5000', meant for really old compilers indeed only. It is always best to pick the flags individually unless we are absolutely sure a set of flags was introduced to the toolchain together (`-march=sb1' and `-mtune=sb1' would be a good example), and this change makes it happen for CONFIG_CPU_SB1. Consequently the flags ultimately selected with GCC 4.1.2 are `-march=sb1 -Wa,--trap -mno-mips3d' Signed-off-by: Maciej W.

2014-07-30MIPS: asm/bitops.h: Guard CLZ with `.set mips32'Maciej W. Rozycki1-1/+7
This fixes: {standard input}: Assembler messages: {standard input}:145: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2' {standard input}:920: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$9' {standard input}:1797: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:1851: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:2831: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:4209: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:4329: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2' make[2]: *** [arch/mips/mm/tlbex.o] Error 1 which triggered due to a regression causing the file to be built with `-march=r5000' rather than `-march=sb1', fixed separately. Nevertheless the error should not happen, the other uses of CLZ are appropriately guarded. This change copies the arrangement from one of those other places. Signed-off-by: Maciej W.

2014-07-30MIPS: BCM63xx: Replace irq dispatch code with a generic versionJonas Gorski1-74/+56
The generic version uses a variable length of u32 registers instead of u32/u64. This allows easier support for "wider" registers without having to rewrite everything. This "generic" version is as fast as the old version in the best case (i == next set bit), and twice as fast in the worst case in 64 bits. Using a macro was chosen over a (forced) inline version because gcc generated more compact code with the macro. The change from (signed) int to unsigned int for i and to_call was intentional as the value can be only between 0 and (width - 1) anyway, and allowed gcc to optimise the code a bit further.

2014-07-30MIPS: Alchemy: clock framework integration of onchip clocksManuel Lauss4-2/+1115
This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted.

2014-07-28KVM: Rename and add argument to check_extensionAlexander Graf1-1/+1
In preparation to make the check_extension function available to VM scope we add a struct kvm * argument to the function header and rename the function accordingly. It will still be called from the /dev/kvm fd, but with a NULL argument for struct kvm *. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Paolo Bonzini <pbonzini@redhat.com>

2014-07-27staging: silicom: remove driverKristina Martšenko1-1/+0
The driver hasn't been cleaned up and it doesn't look like anyone is working on it anymore (including the original author). So remove it. If someone wants to work on cleaning the driver up and moving it out of staging, this commit can be reverted. In addition, since this removes the CONFIG_NET_VENDOR_SILICOM config symbol, remove the symbol from all defconfig files that reference it.

2014-07-18MIPS: ftrace: Add call to ftrace_graph_is_dead() in function graph codeSteven Rostedt (Red Hat)1-0/+3
ftrace_stop() is going away as it disables parts of function tracing that affects users that should not be affected. But ftrace_graph_stop() is built on ftrace_stop(). Here's another example of killing all of function tracing because something went wrong with function graph tracing. Instead of disabling all users of function tracing on function graph error, disable only function graph tracing. To do this, the arch code must call ftrace_graph_is_dead() before it implements function graph.

2014-07-18tgt: defconfig cleanupBart Van Assche16-20/+0
Because of the removal of the scsi_tgt kernel module, the kbuild variables CONFIG_SCSI_TGT, CONFIG_SCSI_SRP_TGT_ATTRS and CONFIG_SCSI_FC_TGT_ATTRS are obsolete. This patch removes these variables. This patch is the result of the following command: find -name '*defconfig' | while read f; do grep -vwE 'CONFIG_SCSI_TGT|CONFIG_SCSI_SRP_TGT_ATTRS|CONFIG_SCSI_FC_TGT_ATTRS|CONFIG_SRP' $f >/tmp/t && mv /tmp/t $f; done Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.de>
2014-07-17arch, locking: Ciao arch_mutex_cpu_relax()Davidlohr Bueso1-0/+1
The arch_mutex_cpu_relax() function, introduced by 34b133f, is hacky and ugly. It was added a few years ago to address the fact that common cpu_relax() calls include yielding on s390, and thus impact the optimistic spinning functionality of mutexes. Nowadays we use this function well beyond mutexes: rwsem, qrwlock, mcs and lockref. Since the macro that defines the call is in the mutex header, any users must include mutex.h and the naming is misleading as well. This patch (i) renames the call to cpu_relax_lowlatency ("relax, but only if you can do it with very low latency") and (ii) defines it in each arch's asm/processor.h local header, just like for regular cpu_relax functions. On all archs, except s390, cpu_relax_lowlatency is simply cpu_relax, and thus we can take it out of mutex.h. While this can seem redundant, I believe it is a good choice as it allows us to move out arch specific logic from generic locking primitives and enables future(?) archs to transparently define it, similarly to System Z.
