-Subject: [PATCH] lib/idr.c: Fix bug introduced by RCU fix
-
-The last patch to lib/idr.c caused a bug if idr_get_new_above() was
-called on an empty idr:
-Usually, nodes stay on the same layer. New layers are added to the top
-of the tree.
-The exception is idr_get_new_above() on an empty tree: In this case,
-the new root node is first added on layer 0, then moved upwards.
-p->layer was not updated.
-
-As usual: You shall never rely on the source code comments, they
-will only mislead you.

-SUNRPC: Fix a performance regression in the RPC authentication code
-
-Fix a regression reported by Max Kellermann whereby kernel profiling
-showed that his clients were spending 45% of their time in
-rpcauth_lookup_credcache.
-
-It turns out that although his processes had identical uid/gid/groups,
-generic_match() was failing to detect this, because the task->group_info
-pointers were not shared. This again lead to the creation of a huge number
-of identical credentials at the RPC layer.
-
-The regression is fixed by comparing the contents of task->group_info
-if the actual pointers are not identical.

-Subject: [PATCH] Fix memory corruption during IR initialization for various
tuner cards
-
-In two different places the IR_i2c_init_data structure is used to store some
-data for particular cards that will later override the settings that would
-otherwise be used by the ir-kbd-i2c driver in ir_probe(). The way those
-settings get there is problematic: init_data is on the stack, and a pointer to
-it is stored to be used after the function that sets it up returns. Not good.
-
-init_data might be overwritten by the time ir_probe() runs. ir_probe() will
-then call ir_input_init(), which proceeds to fill out the dev->keybit bit
-array with a 1 in the appropriate slot for every key on the tuner's remote.
-
-But if the keymap pointer now points to random garbage, that will be used
-instead to determine where to write each 1. And since IR_KEYTAB_TYPE is u32,
-it can be write millions of bits past the end of dev->keybit. Essentially
-this bug writes a 1 to up to 128 random bits in memory, stopping early (and
-oopsing) if or when it hits an invalid page.
-
-To fix this, I define a static IR_i2c_init_data struct for each card that
-needs one rather than creating the data on the stack. This way, I can supply a
-pointer that will remain valid. Also I don't have to allocate memory just to
-store information that's already known at compile time and I don't have bother
-freeing it, either.
-
-This fixes a regression caused by commit 4d7a2d6721.
