Name: [v3] riscv: hwprobe: allow querying available RISCV_HWPROBE_KEY_IMA_EXT_0 bits

riscv: hwprobe: allow querying available RISCV_HWPROBE_KEY_IMA_EXT_0 …
6cc680a 
…bits

When probing for extensions using RISCV_HWPROBE_KEY_IMA_EXT_0, a missing
bit in the resulting bitmask means the extension is not available or the
kernel is not recent enough to support the bit. Currently, there's no
way to differentiate between the two.

This adds a new riscv_hwprobe key, RISCV_HWPROBE_KEY_IMA_EXT_0_AVAIL,
which returns a bitmask of all the queryable extensions supported by the
kernel in RISCV_HWPROBE_KEY_IMA_EXT_0. This can allow programs to use a
fallback extension detection method when the bit they want to query is
not available in the kernel they are running on.
