The fixes are specific to kdb # (pure kgdb debugging does not use the console system at all). On # systems with an NMI then kdb, if it is enabled, must get messages to # the user despite potentially running from some "difficult" calling # contexts. These fixes avoid using the console system where we have # been provided an alternative (safer) way to interact with the user # and, if using the console system in unavoidable, use oops_in_progress # for deadlock avoidance. These fixes also ensure kdb honours the # console enable flag. # # Also included is a fix that wraps kgdb trap handling in an RCU read # lock to avoids triggering diagnostic warnings. This is a wide lock # scope but this is OK because kgdb is a stop-the-world debugger. When # we stop the world we put all the CPUs into holding pens and this # inhibits RCU update anyway" # # * tag 'kgdb-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux: # kgdb: Avoid suspicious RCU usage warning # kdb: Switch to use safer dbg_io_ops over console APIs # kdb: Make kdb_printf() console handling more robust # kdb: Check status of console prior to invoking handlers # kdb: Re-factor kdb_printf() message write code # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 6116dea80dfd5b8d3825bf7f2e44a8bc2730f3d0 # < make -s -j 48 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- defconfig # < make -s -j 48 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- help # make -s -j 48 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- olddefconfig # make -s -j 48 ARCH=ia64 O=/kisskb/build/linus_ia64-defconfig_ia64-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/ia64-linux/bin/ia64-linux- :1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/ia64/include/uapi/asm/intrinsics.h:22:0, from /kisskb/src/arch/ia64/include/asm/intrinsics.h:11, from /kisskb/src/arch/ia64/include/asm/bitops.h:19, from /kisskb/src/include/linux/bitops.h:29, from /kisskb/src/include/linux/kernel.h:12, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/preempt.h:11, from /kisskb/src/include/linux/spinlock.h:51, from /kisskb/src/include/linux/seqlock.h:36, from /kisskb/src/include/linux/time.h:6, from /kisskb/src/fs/nfs/read.c:11: /kisskb/src/fs/nfs/read.c: In function 'nfs_read_completion': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__(*(ptr))) __xchg((unsigned long) (x), (ptr), sizeof(*(ptr)))) ^ /kisskb/src/fs/nfs/read.c:196:5: note: in expansion of macro 'xchg' xchg(&nfs_req_openctx(req)->error, error); ^ /kisskb/src/fs/nfs/read.c: In function 'nfs_readpage': /kisskb/src/arch/ia64/include/uapi/asm/cmpxchg.h:57:2: warning: value computed is not used [-Wunused-value] ((__typeof__(*(ptr))) __xchg((unsigned long) (x), (ptr), sizeof(*(ptr)))) ^ /kisskb/src/fs/nfs/read.c:355:2: note: in expansion of macro 'xchg' xchg(&ctx->error, 0); ^ No errors detected in 22250 functions.
