[PATCH v2 4/4] powerpc/pseries: warn if recursing into the hcall tracing code

The hcall tracing code has a recursion check built in, which skips tracing if we are already tracing an hcall. However if the tracing code has problems with recursion, this check may not catch all cases because the tracing code could be invoked from a different tracepoint first, then make an hcall

[PATCH v2 3/4] powerpc/pseries: use notrace hcall variant for H_CEDE idle

Rather than special-case H_CEDE in the hcall trace wrappers, make the idle H_CEDE call use plpar_hcall_norets_notrace(). Reviewed-by: Naveen N. Rao Signed-off-by: Nicholas Piggin --- arch/powerpc/include/asm/plpar_wrappers.h | 6 +- arch/powerpc/platforms/pseries/lpar.c | 10 --

[PATCH v2 2/4] powerpc/pseries: Don't trace hcall tracing wrapper

[PATCH v2 0/4] Fix queued spinlocks and a bit more

This didn't seem to send properly, apologies if you get a duplicate. Patch 1 is the important fix. 2 might fix something, although I haven't provoked a crash yet. Patch 3 is a small cleanup, and patch 4 I think is the right thing to do but these could wait for later. Since v1: - Improved comment

[PATCH v2 1/4] powerpc/pseries: Fix hcall tracing recursion in pv queued spinlocks

The paravit queued spinlock slow path adds itself to the queue then calls pv_wait to wait for the lock to become free. This is implemented by calling H_CONFER to donate cycles. When hcall tracing is enabled, this H_CONFER call can lead to a spin lock being taken in the tracing code, which will res

[PATCH] powerpc/signal: Fix possible build failure with unsafe_copy_fpr_{to/from}_user

When neither CONFIG_VSX nor CONFIG_PPC_FPU_REGS are selected, unsafe_copy_fpr_to_user() and unsafe_copy_fpr_from_user() are doing nothing. Then, unless the 'label' operand is used elsewhere, GCC complains about it being defined but not used. To fix that, add an impossible 'goto label'. Signed-of
