2008-10-30edac x38: new MC driver moduleHitoshi Mitake
I wrote a new module for Intel X38 chipset. This chipset is very similar to Intel 3200 chipset, but there are some different points, so I copyed i3200_edac.c and modified. This is Intel's web page describing this chipset. http://www.intel.com/Products/Desktop/Chipsets/X38/X38-overview.htm I've tested this new module with broken memory, and it seems to be working well.

2008-10-30mm: increase the default mlock limit from 32k to 64kKurt Garloff
By default, non-privileged tasks can only mlock() a small amount of memory to avoid a DoS attack by ordinary users. The Linux kernel defaulted to 32k (on a 4k page size system) to accommodate the needs of gpg. However, newer gpg2 needs 64k in various circumstances and otherwise fails miserably, see bnc#329675. Change the default to 64k, and make it more agnostic to PAGE_SIZE.

2008-10-30i2c-s3c2410: Correct use of ! and &Julia Lawall
In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. In particular, the result of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN is always 0.

2008-10-30MIPS: Sort out CPU type to name translation.Ralf Baechle
As noticed by David Daney <ddaney@caviumnetworks.com>, the old long switch statement did not comply with the Linux C coding style. It was also yet another place of code to be changed when adding a new processor type leading to annoying bugs for example in /proc/cpuinfo. Fixed by moving the setting of the CPU type string into the core of the probing code and a few BUG_ON() test to ensure the CPU probing code indeed did its job and removing multiple now redundant tests.

2008-10-30dm snapshot: wait for chunks in destructorMikulas Patocka
If there are several snapshots sharing an origin and one is removed while the origin is being written to, the snapshot's mempool may get deleted while elements are still referenced. Prior to dm-snapshot-use-per-device-mempools.patch the pending exceptions may still have been referenced after the snapshot was destroyed, but this was not a problem because the shared mempool was still there. This patch fixes the problem by tracking the number of mempool elements in use. The scenario: - You have an origin and two snapshots 1 and 2. - Someone writes to the origin. - It creates two exceptions in the snapshots, snapshot 1 will be primary exception, snapshot 2's pending_exception->primary_pe will point to the exception in snapshot 1. - The exceptions are being relocated, relocation of exception 1 finishes (but it's pending_exception is still allocated, because it is referenced by an exception from snapshot 2) - The user lvremoves snapshot 1 --- it calls just suspend (does nothing) and destructor. md->pending is zero (there is no I/O submitted to the snapshot by md layer), so it won't help us. - The destructor waits for kcopyd jobs to finish on snapshot 1 --- but there are none. - The destructor on snapshot 1 cleans up everything. - The relocation of exception on snapshot 2 finishes, it drops reference on primary_pe. This frees its primary_pe pointer. Primary_pe points to pending exception created for snapshot 1. So it frees memory into non-existing mempool.

2008-10-30dm snapshot: fix register_snapshot deadlockMikulas Patocka
register_snapshot() performs a GFP_KERNEL allocation while holding _origins_lock for write, but that could write out dirty pages onto a device that attempts to acquire _origins_lock for read, resulting in deadlock. So move the allocation up before taking the lock. This path is not performance-critical, so it doesn't matter that we allocate memory and free it if we find that we won't need it.

2008-10-30HID: add quirk entry for no-name keyboard (0x13ba/0x0017)Alan Stern
This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter to the hid-dell driver. (The device shows up with a Product string saying "Generic USB K/B", nothing more.) This will force an initial "Set-LEDs" report to be sent to the device, without which it won't send any keystroke information. Several bug reports mentioning this device have been filed in various forums; the patch should resolve them. This is just a temporary stop-gap for 2.6.28. A later patch for 2.6.29 will introduce a more generic mechanism for "Set-LEDs", making this change (and the entire hid-dell driver) unnecessary.

2008-10-29Driver core: fix 'dynamic_debug' cmd line parameterJason Baron
In testing 2.6.28-rc1, I found that passing 'dynamic_printk' on the command line didn't activate the debug code. The problem is that dynamic_printk_setup() (which activates the debugging) is being called before dynamic_printk_init() is called (which initializes infrastructure). Fix this by setting setting the state to 'DYNAMIC_ENABLED_ALL' in dynamic_printk_setup(), which will also cause all subsequent modules to have debugging automatically started, which is probably the behavior we want.

2008-10-29USB: prevent autosuspend during hub initializationAlan Stern
This patch (as1153) fixes a potential problem in hub initialization. Starting in 2.6.28, initialization was split into several tasks to help speed up booting. This opens the possibility that the hub may be autosuspended before all the initialization tasks can complete. Normally that wouldn't matter, but with incomplete initialization there is a risk that the hub would never autoresume -- especially if devices were plugged into the hub beforehand. The solution is a simple one-line change to suppress autosuspend until the initialization is finished.

2008-10-29USB: fix crash when URBs are unlinked after the device is goneAlan Stern
This patch (as1151) protects usbcore against drivers that try to unlink an URB after the URB's device or bus have been removed. The core does not currently check for this, and certain drivers can cause a crash if they are running while an HCD is unloaded. Certainly it would be best to fix the guilty drivers. But a little defensive programming doesn't hurt, especially since it appears that quite a few drivers need to be fixed. The patch prevents the problem by grabbing a reference to the device while an unlink is in progress and using a new spinlock to synchronize unlinks with device removal. (There's no need to acquire a reference to the bus as well, since the device structure itself keeps a reference to the bus.) In addition, the kerneldoc is updated to indicate that URBs should not be unlinked after the disconnect method returns.

2008-10-29Fix incompatibility with versions of Perl less than 5.6.0Jeremy Huntwork
Fix headers_install.pl and headers_check.pl to be compatible with versions of Perl less than 5.6.0. It has been tested with Perl 5.005_03 and 5.8.8. I realize this may not be an issue for most people, but there will still be some that hit it, I imagine. There are three basic issues: 1. Prior to 5.6.0 open() only used 2 arguments, and the versions of the scripts in 2.6.27.1 use 3. 2. 5.6.0 also introduced the ability to use uninitialized scalar variables as file handles, which the current scripts make use of. 3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use the -w switch and be backwards compatible.
