The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone can write) permissions on its writable sysfs entries. Alter the permissions to 0220 (owner and group can write). The use case for this driver is to configure the fail over behavior of the clock hardware. That should be done by the more privileged users. Signed-off-by:

Remove dead code from tty_io.c release_dev() Signed-off-by:

Paul Fulghum authored
Remove duplicate call to idr_remove() in ptmx_open. Error during open can result in call to release_dev() followed by call to idr_remove(). release_dev already calls idr_remove so the second call can cause a stack dump in idr_remove()->sub_remove() flagging an attempt to release an already released entry. I reproduces this on a machine with a misconfigured X server (attempting to restart multiple times rapidly) getting the same error as the 1st link below. This also seems to be related to: http://marc.theaimsgroup.com/?l=selinux&m=110536513426735&w=2 http://marc.theaimsgroup.com/?l=selinux&m=110596994916785&w=2 The stack dump can occur on close (as well as open) as shown in the 1st instance above, possible from something like: process A - open (index=0), open fail to out1, release_dev calls idr_remove (index 0), down(sem) sleeps process B - open (index=0), open OK (idr allocated) process A - wake and call idr_remove on index 0 ... process B - close, release_dev, stack dump on idr_remove (index=0) because entry already removed Signed-off-by:

Remove the blkmtd driver. - An alternative exists (block2mtd) that hasn't had bug report for > 1 year. - Most embedded people tend to use ancient kernels with custom patches from mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts them too much. - It's in the way of klibc. The problems caused by pulling blkmtd support are fairly low, while the problems caused by delaying klibc can be fairly substantial. At best, this would be a severe burden on hpa's time.

The only record we have of the real-time age of a process, regardless of execs it's done, is start_time. When a non-leader thread exec, the original start_time of the process is lost. Things looking at the real-time age of the process are fooled, for example the process accounting record when the process finally dies. This change makes the oldest start_time stick around with the process after a non-leader exec. This way the association between PID and start_time is kept constant, which seems correct to me.

If SELECT_STACK_ALLOC is not a multiple of sizeof(long) then stack_fds[] would be shorter than SELECT_STACK_ALLOC bytes and could overflow later in the function. Fixed by simply rearranging the test later to work on sizeof(stack_fds) Currently SELECT_STACK_ALLOC is 256 so this doesn't happen, but it's nasty to have things like this hidden in the code. What if later someone decides to change SELECT_STACK_ALLOC to 300? Signed-off-by:

We need the boot CPU's tvec_bases[] entry to be initialised super-early in boot, for early_serial_setup(). That runs within setup_arch(), before even per-cpu areas are initialised. The patch changes tvec_bases to use compile-time initialisation, and adds a separate array `tvec_base_done' to keep track of which CPU has had its tvec_bases[] entry initialised (because we can no longer use the zeroness of that tvec_bases[] entry to determine whether it has been initialised).

Some string functions were safely overrideable in lib/string.c, but their corresponding declarations in linux/string.h were not. Correct this, and make strcspn overrideable. Odds of someone wanting to do optimized assembly of these are small, but for the sake of cleanliness, might as well bring them into line with the rest of the file. Signed-off-by:

While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler. See also: http://marc.theaimsgroup.com/?l=linux-kernel&m=114358010523896&w=2Signed-off-by:
