2017-07-06counter: use correct unit for indicesJason A. Donenfeld
Even though redundant bits == bits per long, we're indexing into something that uses longs as its unit, so this is correct. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-05-31data: enable BH during parallel crypto on ARM/NEONJason A. Donenfeld
padata disables it, but in order to use SIMD on ARM, we can't be in an interrupt. We only do this on ARM since it adds jitter to the performance. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-04-09data: alloca is actually as dangerous as they sayJason A. Donenfeld
It turns out that calling alloca from an inline function means that the memory isn't ever deallocated until the caller function exits, which means we were using tons of stack space for every iteration of the call. So, we hard code the sg array. While 128 seems like a reasonable number, we actually wind up using "MAX_SKB_FRAGS * 2 + 1". An skb has its data segment, so that's 1. Then it has its frags, which are MAX_SKB_FRAGS at max. Then it has its frag list, which, so far as I can tell, are potentially unbounded. So we just hope it's no more than MAX_SKB_FRAGS, and so we plan for at most two of those. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

All locks are potentially between user context and softirq, which means we need to take the _bh variant. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
