From 1bff779285f89cd0b62955c20cca70ada4074236 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Wed, 24 Mar 2010 11:49:52 +0100 Subject: [S390] system.h: Fix compile error for 1 and 2 byte cmpxchg commit 024914477e15ef8b17f271ec47f1bb8a589f0806 "memcg: move charges of anonymous swap" revealed that the 1 byte and 2 byte cmpxchg is currently broken: arch/s390/include/asm/system.h: Assembler messages: arch/s390/include/asm/system.h:241: Error: junk at end of line: `(%r5)' make[1]: *** [mm/page_cgroup.o] Error 1 make[1]: *** Waiting for unfinished jobs.... It turned out that commit 987bcdacb18a3adc2a48d85c9b005069c2f4dd7b ([S390] use inline assembly contraints available with gcc 3.3.3) broke the inline assembly. The or operands are now in constraint 3 and 4 instead of 2 and 3.
