[PATCH] Fix NULL pointer dereference in node_read_numastat()

2006-04-07T16:44:29Z

Fix NULL pointer dereference in node_read_numastat() zone_pcp() only returns valid values if the processor is online. Change node_read_numastat() to only scan online processors. Signed-off-by: Christoph Lameter Signed-off-by: Greg Kroah-Hartman

[PATCH] firmware: fix BUG: in fw_realloc_buffer

2006-03-28T06:47:30Z

The fw_realloc_buffer routine does not handle an increase in buffer size of more than 4k. It's not clear to me why it expects that it will only get an extra 4k of data. The attached patch modifies fw_realloc_buffer to vmalloc as much memory as is requested, instead of what we previously had + 4k. I've tested this on my laptop, which would crash occaisionally on boot without the patch. With the patch, it hasn't crashed, but I can't be certain that this code path is exercised.

[PATCH] drivers/base/: proper prototypes

2006-02-06T20:17:17Z

This patch contains the following changes: - move prototypes to base.h - sys.c should #include "base.h" for getting the prototype of it's global function system_bus_init() Note that hidden in this patch there's a bugfix: Caller and callee disagreed regarding the return type of sysdev_shutdown().

[PATCH] Fix compiler warning in driver core for CONFIG_HOTPLUG=N

2006-02-06T20:17:17Z

FYI, while running a build test, I found: drivers/base/bus.c:166: warning: `driver_attr_unbind' defined but not used drivers/base/bus.c:194: warning: `driver_attr_bind' defined but not used Looks like these two attributes and supporting functions want to be #ifdef HOTPLUG'd Signed-off-by: Russell King Signed-off-by: Greg Kroah-Hartman

[PATCH] Export cpu topology in sysfs

2006-02-03T16:32:09Z

The patch implements cpu topology exportation by sysfs. Items (attributes) are similar to /proc/cpuinfo. 1) /sys/devices/system/cpu/cpuX/topology/physical_package_id: represent the physical package id of cpu X; 2) /sys/devices/system/cpu/cpuX/topology/core_id: represent the cpu core id to cpu X; 3) /sys/devices/system/cpu/cpuX/topology/thread_siblings: represent the thread siblings to cpu X in the same core; 4) /sys/devices/system/cpu/cpuX/topology/core_siblings: represent the thread siblings to cpu X in the same physical package; To implement it in an architecture-neutral way, a new source file, driver/base/topology.c, is to export the 5 attributes. If one architecture wants to support this feature, it just needs to implement 4 defines, typically in file include/asm-XXX/topology.h. The 4 defines are: #define topology_physical_package_id(cpu) #define topology_core_id(cpu) #define topology_thread_siblings(cpu) #define topology_core_siblings(cpu) The type of **_id is int. The type of siblings is cpumask_t. To be consistent on all architectures, the 4 attributes should have deafult values if their values are unavailable. Below is the rule. 1) physical_package_id: If cpu has no physical package id, -1 is the default value. 2) core_id: If cpu doesn't support multi-core, its core id is 0. 3) thread_siblings: Just include itself, if the cpu doesn't support HT/multi-thread. 4) core_siblings: Just include itself, if the cpu doesn't support multi-core and HT/Multi-thread. So be careful when declaring the 4 defines in include/asm-XXX/topology.h. If an attribute isn't defined on an architecture, it won't be exported. Thank Nathan, Greg, Andi, Paul and Venki.

[PATCH] device_shutdown can loop if the driver frees itself

2006-01-13T19:26:12Z

This patch changes device_shutdown() to use the newly introduced safe reverse list traversal. We experienced loops on system reboot if we had removed and re-inserted our device from the device list. We noticed this problem on PPC405. Our PCI IDE device comes and goes a lot. Our hypothesis was that there was a loop caused by the driver->shutdown freeing memory. It is possible that we do something wrong as well, but being unable to reboot is kind of nasty.
