From: Max Filippov <jcmvbkbc@gmail.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 7de7ac785ae18a2cdc78d7560f48e3213d9ea0ab upstream. There are XCHAL_NUM_DBREAK registers, clear them all. This also fixes cryptic assembler error message with binutils 2.25 when XCHAL_NUM_DBREAK is 0: as: out of memory allocating 18446744073709551575 bytes after a total of 495616 bytes Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz> --- arch/xtensa/kernel/head.S | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/xtensa/kernel/head.S b/arch/xtensa/kernel/head.S index 7d740ebbe198..bb12d778f64f 100644 --- a/arch/xtensa/kernel/head.S +++ b/arch/xtensa/kernel/head.S @@ -118,7 +118,7 @@ ENTRY(_startup) wsr a0, icountlevel .set _index, 0 - .rept XCHAL_NUM_DBREAK - 1 + .rept XCHAL_NUM_DBREAK wsr a0, SREG_DBREAKC + _index .set _index, _index + 1 .endr -- 2.8.1
