Paul Burton 7d73d57211 MIPS: math-emu: Reuse name array in debugfs_fpuemu() ... The FPU_STAT_CREATE_EX() macro used 114 times in debugfs_fpuemu() declares a 32 byte char array to hold the name of a debugfs file. Since each use of the macro declares a new char array out of the scope of all the other uses, we end up with an unnecessarily large stack frame of 3648 bytes (ie. 114*32) plus the size of 2 pointers (fpuemu_debugfs_base_dir & fpuemu_debugfs_inst_dir). This is enough to trigger the frame size warnings from GCC in common configurations. Avoid the unnecessary stack bloat by using a single name char array which each usage of FPU_STAT_CREATE_EX() will reinitialize via the strcpy() in adjust_instruction_counter_name().
