[PATCH] perf/arm-cmn: Fix CMN S3 DTM offset

by Robin Murphy

CMN S3's DTM offset is different between r0px and r1p0, and it turns out this was not a error in the earlier documentation, but does actually exist in the design. Lovely.

[PATCH] nvdimm: ndtest: Add check for devm_kcalloc() allocations in ndtest_probe()

by Guangshuo Li

devm_kcalloc() may fail. ndtest_probe() allocates three DMA address arrays (dcr_dma, label_dma, dimm_dma) and later unconditionally uses them in ndtest_nvdimm_init(), which can lead to a NULL pointer dereference on allocation failure. Add NULL checks for all three allocations and return -ENOMEM if any allocation fails.

[PATCH] net: liquidio: fix overflow in octeon_init_instr_queue()

by Alexey Nepomnyashih

The expression `(conf->instr_type == 64) << iq_no` can overflow because `iq_no` may be as high as 64 (`CN23XX_MAX_RINGS_PER_PF`). Casting the operand to `u64` ensures correct 64-bit arithmetic. Found by Linux Verification Center (linuxtesting.org) with SVACE.
