From eacb6ec9ae5932ea02a44268684a56e4b5996ccf Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Thu, 19 Jan 2012 12:37:13 +0100 Subject: microblaze: generic atomic64 support This tiny patch adds generic atomic64 support for the Microblaze architecture. The patch is against the latest linux-2.6-microblaze tree. It also fixes the kernel build for microblaze: Error log: CC kernel/trace/trace_clock.o kernel/trace/trace_clock.c:117: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'trace_counter' kernel/trace/trace_clock.c: In function 'trace_clock_counter': kernel/trace/trace_clock.c:126: error: implicit declaration of function 'atomic64_add_return' kernel/trace/trace_clock.c:126: error: 'trace_counter' undeclared (first use in this function) kernel/trace/trace_clock.c:126: error: (Each undeclared identifier is reported only once kernel/trace/trace_clock.c:126: error: for each function it appears in.) make[2]: *** [kernel/trace/trace_clock.o] Error 1 make[1]: *** [kernel/trace] Error 2 make: *** [kernel] Error 2 Signed-off-by: Ariane Keller Signed-off-by: Daniel Borkmann Signed-off-by: Michal Simek --- arch/microblaze/Kconfig | 1 + arch/microblaze/include/asm/atomic.h | 1 + 2 files changed, 2 insertions(+) diff --git a/arch/microblaze/Kconfig b/arch/microblaze/Kconfig index 74f23a460ba..c8d6efb99db 100644 --- a/arch/microblaze/Kconfig +++ b/arch/microblaze/Kconfig @@ -19,6 +19,7 @@ config MICROBLAZE select GENERIC_IRQ_SHOW select GENERIC_PCI_IOMAP select GENERIC_CPU_DEVICES + select GENERIC_ATOMIC64 config SWAP def_bool n diff --git a/arch/microblaze/include/asm/atomic.h b/arch/microblaze/include/asm/atomic.h index 6d2e1d418be..615f53992c6 100644 --- a/arch/microblaze/include/asm/atomic.h +++ b/arch/microblaze/include/asm/atomic.h @@ -2,6 +2,7 @@ #define _ASM_MICROBLAZE_ATOMIC_H #include +#include /* * Atomically test *v and decrement if it is greater than 0. -- cgit v1.2.3-70-g09d2
