PROBLEM: Linux kernel.core_pattern with pipes does argument splitting after template expansion

The Linux kernel.core_pattern support for core dump handlers using the pipe syntax does argument splitting after template expansion. At minimum this bug could cause truncated values for the executable name. This also means that the argument parsing for core dump handlers is slightly more

[RESEND PATCH v2 5/5] lib/list_sort: Optimize number of calls to comparison function

CONFIG_RETPOLINE has severely degraded indirect function call performance, so it's worth putting some effort into reducing the number of times cmp() is called. This patch avoids badly unbalanced merges on unlucky input sizes. It slightly increases the code size, but saves an average of 0.2*n

[RESEND PATCH v2 2/5] lib/sort: Use more efficient bottom-up heapsort variant

This uses fewer comparisons than the previous code (approaching half as many for large random inputs), but produces identical results; it actually performs the exact same series of swap operations. Specifically, it reduces the average number of compares from 2*n*log2(n) - 3*n + o(n) to

[RESEND PATCH v2 4/5] lib/list_sort: Simplify and remove MAX_LIST_LENGTH_BITS

[RESEND PATCH v2 1/5] lib/sort: Make swap functions more generic

Rather than having special-case swap functions for 4- and 8-byte objects, special-case aligned multiples of 4 or 8 bytes. This speeds up most users of sort() by avoiding fallback to the byte copy loop. Despite what commit ca96ab859ab4 ("lib/sort: Add 64 bit swap function") claims, very few users
