[PATCH 2/2] perf annotate: add powerpc support

Convert ins__find() to a __weak function for generic functionality, while adding a powerpc-specific variant. We look at the function name for branch instructions and classify the instructions to one among a branch, a function call (branch with LR update) or a function return (branch to LR). Cc:

[PATCH] powerpc: convert 'iommu_alloc failed' messages to dynamic debug

This prevents flooding the logs with 'iommu_alloc failed' messages while I/O is performed (normally) to very fast devices (e.g. NVMe). That error is not necessarily a problem; device drivers can retry later / reschedule the requests for which the allocation failed, and handle things gracefully

Hi, This is fourth approach for replacing struct dma_attrs with unsigned long. The main patch (1/44) doing the change is split into many subpatches for easier review (2-42). They should be squashed together when applying. *Important:* Patchset is tested on my ARM platforms and *only* build

[PATCH 2/2] crypto: vmx: Increase priority of aes-cbc cipher

From: Anton Blanchard All of the VMX AES ciphers (AES, AES-CBC and AES-CTR) are set at priority 1000. Unfortunately this means we never use AES-CBC and AES-CTR, because the base AES-CBC cipher that is implemented on top of AES inherits its priority. To fix this, AES-CBC and

[PATCH 1/2] crypto: vmx: Fix ABI detection

From: Anton Blanchard When calling ppc-xlate.pl, we pass it either linux-ppc64 or linux-ppc64le. The script however was expecting linux64le, a result of its OpenSSL origins. This means we aren't obeying the ppc64le ABIv2 rules. Fix this by checking for linux-ppc64le. Fixes:
