- * Options for cacheflush system call.
- *
- * The ICACHE flush is performed on all cores currently running the
- * current process's address space. The intent is for user
- * applications to be able to modify code, invoke the system call,
- * then allow arbitrary other threads in the same address space to see
- * the newly-modified code. Passing a length of CHIP_L1I_CACHE_SIZE()
- * or more invalidates the entire icache on all cores in the address
- * spaces. (Note: currently this option invalidates the entire icache
- * regardless of the requested address and length, but we may choose
- * to honor the arguments at some point.)
- *
- * Flush and invalidation of memory can normally be performed with the
- * __insn_flush() and __insn_finv() instructions from userspace.
- * The DCACHE option to the system call allows userspace
- * to flush the entire L1+L2 data cache from the core. In this case,
- * the address and length arguments are not used. The DCACHE flush is
- * restricted to the current core, not all cores in the address space.
