Call the mutex slowpath more conservatively - e.g. FRAME_POINTERS can change the calling convention, in which case a direct branch to the slowpath becomes illegal. Bug found by Hugh Dickins. Signed-off-by:

We're starting a number of big applications (memory footprint app. 1MByte) on our Arcturus uC5272. Therefore memory fragmentation is a real pain for us. We've switched to uClinux-2.4.27-uc1 and found that page_alloc2 fragments the memory heavily. Digging into it we found a bug in the find_next_zero_bit function in the m68knommu/bitops.h file. if the size isn't a multiple of 32 than the upper bits of the last word to be searched should be masked. But the functions masks the lower bits of the last word because it uses a right shift instead of a left shift operator. Patch submitted by Sascha Smejkal <s.smejkal@centersystems.at> Signed-off-by:

Modify the initial trace output (which is based on flags in the binary header) so that it is not done until after the magic number check. This may well not be a flat format binary, so the flags could be invalid. (Prime example, running a script). Changes prompted by patches from Stuart Hughs. Signed-off-by:

Set the hardware interrupt priority to a different value for each attached ColdFire serial port. According to the CPU documentation you should not use the same combination of level/priority on more than one device. People have reported odd serial port behavior with them set the same. Signed-off-by:

This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.

We want to wait for the cl_users to go down to zero, not for it to stay positive. Quoth Trond (who wasn't even the author, but acked the wrong version): "Argh! I need to increase my daily caffeine dosages." Signed-off-by: -

Pointed out by Srivatsa Vaddagiri <vatsa@in.ibm.com>. rcu_do_batch() stops after processing maxbatch callbacks on ->donelist leaving rcu_tasklet in TASKLET_STATE_SCHED state. If CPU_DEAD event happens remaining ->donelist entries are lost, rcu_offline_cpu() kills this tasklet. With this patch ->donelist migrates along with ->curlist and ->nxtlist to the current cpu. Compile tested. Signed-off-by:

This patch moves rcu_state into the rcu_ctrlblk. I think there are no reasons why we should have 2 different variables to control rcu state. Every user of rcu_state has also "rcu_ctrlblk *rcp" in the parameter list. Signed-off-by:

DM doesn't need to bounce bio's on its own, but the block layer defaults to that in blk_queue_make_request(). The lower level drivers should bounce ios themselves, that is what they need to do if not layered below dm anyways. Signed-off-by:

In the process of optimising our per cpu data code, I found a ppc64 compiler bug that has been around forever. Basically the current RELOC_HIDE can end up trashing r30. Details of the bug can be found at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25572 This bug is present in all compilers before 4.1. It is masked by the fact that our current per cpu data code is inefficient and causes other loads that end up marking r30 as used. A workaround identified by Alan Modra is to use the =r asm constraint instead of =g. Signed-off-by:

I know several people using MAGIC_SYSRQ not for kernel debugging but for trying to do a halfway normal shutdown in case of problems. Since there's no technical reason why MAGIC_SYSRQ would have to depend on DEBUG_KERNEL, I'm therefore suggesting to drop this dependency. Signed-off-by:
