This file is expected to be included multiple times in the same file in order to allow the __SYSCALL macro to generate system call tables. With a global include guard we end up missing __NR_riscv_flush_icache in the syscall table, which results in icache flushes that escape the vDSO call to not actually do anything. The fix is to move to per-#define include guards, which allows the system call tables to actually be populated. Thanks to Macrus Comstedt for finding and fixing the bug!
