| * [PATCH] Serial: Fix small CONFIG_SERIAL_8250_NR_UARTSRussell King2005-06-30
| | | | | | | | | | | | | | | | | | If CONFIG_SERIAL_8250_NR_UARTS is smaller than the array size in asm/serial.h, we trampled on memory which wasn't ours. Take our big boots away by limiting the number of ports initialised to the smaller of ...NR_UARTS and the array size. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * | [PATCH] Driver core: Use klist_del() instead of klist_remove().Patrick Mochel2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | Use klist_del() instead of klist_remove() when unregistering devices. This will prevent a deadlock when executing a recursive unregister using device_for_each_child().

| * | [PATCH] driver core: change bus_rescan_devices to return voidGreg Kroah-Hartman2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | No one was looking at the return value of bus_rescan_devices, and it really wasn't anything that anyone in the kernel would ever care about. So change it which enabled some counting code to be removed also. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * | [PATCH] driver core: Add the ability to bind drivers to devices from userspaceGreg Kroah-Hartman2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a single file, "bind", to the sysfs directory of every driver registered with the driver core. To bind a device to a driver, write the bus id of the device you wish to bind to that specific driver to the "bind" file (remember to not add a trailing \n). If that bus id matches a device on that bus, and it does not currently have a driver bound to it, the probe sequence will be initiated with that driver and device. Note, this requires that the driver itself be willing and able to accept that device (usually through a device id type table). This patch does not make it possible to override the driver's id table.

| * | | [PATCH] ppc64: Replace custom locking code with a spinlockMichael Ellerman2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord which is used for serialising access to the queue. Because it's a word (ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or thereabouts in ItLpQueue.c. The xInUseWord is not shared with they hypervisor, so we can replace it with a spinlock and remove the custom code. There is also another locking mechanism (ItLpQueueInProcess). This is redundant because it's only manipulated while the lock's held. Remove it.

But all these pointers end up pointing to the one place, ie. xItLpQueue. So remove the pointer from the paca struct and just refer to xItLpQueue directly where needed. The only complication is that the spread_lpevents logic was implemented by having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to process events. Instead we just compare the spread_lpevents value to the processor id to get the same behaviour.

* | | | [PATCH] selinux_sb_copy_data() should not require a whole pageEric Paris2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently selinux_sb_copy_data requires an entire page be allocated to *orig when the function is called. This "requirement" is based on the fact that we call copy_page(in_save, nosec_save) and in_save = orig when the data is not FS_BINARY_MOUNTDATA. This means that if a caller were to call do_kern_mount with only about 10 bytes of options, they would get passed here and then we would corrupt PAGE_SIZE - 10 bytes of memory (with all zeros.) Currently it appears all in kernel FS's use one page of data so this has not been a problem. An out of kernel FS did just what is described above and it would almost always panic shortly after they tried to mount. From looking else where in the kernel it is obvious that this string of data must always be null terminated. (See example in do_mount where it always zeros the last byte.) Thus I suggest we use strcpy in place of copy_page. In this way we make sure the amount we copy is always less than or equal to the amount we received and since do_mount is zeroing the last byte this should be safe for all.
