Oprofile is changing the naming it is using for the compatibility modes. Instead of having compat-power<x>, oprofile will go to family naming convention and use ibm-compat-v<x>. Currently only ibm-compat-v1 will be defined. The notion of compatibility events just started with POWER6. So there is no way that any other tool could exist that is using these oprofile_cpu_type strings we want to change.

After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

The x_tables are organized with a table structure and a per-cpu copies of the counters and rules. On older kernels there was a reader/writer lock per table which was a performance bottleneck. In 2.6.30-rc, this was converted to use RCU and the counters/rules which solved the performance problems for do_table but made replacing rules much slower because of the necessary RCU grace period. This version uses a per-cpu set of spinlocks and counters to allow to table processing to proceed without the cache thrashing of a global reader lock and keeps the same performance for table updates.

Commit edada399 broke the build on 64-bit powerpc because it moved the __ftr_alt_* sections of a file away from the .text section, causing link failures due to relative conditional branch targets being too far away from the branch instructions.

hd dance around local irq and HD_IRQ enable without achieving much. It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: NTejun Heo <tj@kernel.org>

During regulator registration, any error after device_register() will cause a double-free on the struct regulator_dev 'rdev'. The bug is in drivers/regulator/core.c:regulator_register(): ... scrub: device_unregister(&rdev->dev); clean: kfree(rdev); <--- rdev = ERR_PTR(ret); goto out; ... device_unregister() calls regulator_dev_release() which frees rdev.

由 Marcel Holtmann 提交于
The Bluetooth 2.1 specification introduced four different security modes that can be mapped using Legacy Pairing and Simple Pairing. With the usage of Simple Pairing it is required that all connections (except the ones for SDP) are encrypted. So even the low security requirement mandates an encrypted connection when using Simple Pairing. When using Legacy Pairing (for Bluetooth 2.0 devices and older) this is not required since it causes interoperability issues. To support this properly the low security requirement translates into different host controller transactions depending if Simple Pairing is supported or not. However in case of Simple Pairing the command to switch on encryption after a successful authentication is not triggered for the low security mode. This patch fixes this and actually makes the logic to differentiate between Simple Pairing and Legacy Pairing a lot simpler.

由 Marcel Holtmann 提交于
The Bluetooth stack uses a reference counting for all established ACL links and if no user (L2CAP connection) is present, the link will be terminated to save power. The problem part is the dedicated pairing when using Legacy Pairing (Bluetooth 2.0 and before). At that point no user is present and pairing attempts will be disconnected within 10 seconds or less. In previous kernel version this was not a problem since the disconnect timeout wasn't triggered on incoming connections for the first time. However this caused issues with broken host stacks that kept the connections around after dedicated pairing. When the support for Simple Pairing got added, the link establishment procedure needed to be changed and now causes issues when using Legacy Pairing When using Simple Pairing it is possible to do a proper reference counting of ACL link users. With Legacy Pairing this is not possible since the specification is unclear in some areas and too many broken Bluetooth devices have already been deployed. So instead of trying to deal with all the broken devices, a special pairing timeout will be introduced that increases the timeout to 60 seconds when pairing is triggered. If a broken devices now puts the stack into an unforeseen state, the worst that happens is the disconnect timeout triggers after 120 seconds instead of 4 seconds. This allows successful pairings with legacy and broken devices now. Based on a report by Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

In 2.6.25 we added UDP mem accounting. This unfortunatly added a penalty when a frame is transmitted, since we have at TX completion time to call sock_wfree() to perform necessary memory accounting. This calls sock_def_write_space() and utimately scheduler if any thread is waiting on the socket. Thread(s) waiting for an incoming frame was scheduled, then had to sleep again as event was meaningless. (All threads waiting on a socket are using same sk_sleep anchor) This adds lot of extra wakeups and increases latencies, as noted by Christoph Lameter, and slows down softirq handler. Reference : http://marc.info/?l=linux-netdev&m=124060437012283&w=2 Fortunatly, Davide Libenzi recently added concept of keyed wakeups into kernel, and particularly for sockets (see commit 37e5540b epoll keyed wakeups: make sockets use keyed wakeups) Davide goal was to optimize epoll, but this new wakeup infrastructure can help non epoll users as well, if they care to setup an appropriate handler. This patch introduces new DEFINE_WAIT_FUNC() helper and uses it in wait_for_packet(), so that only relevant event can wakeup a thread blocked in this function. Trace of function calls from bnx2 TX completion bnx2_poll_work() is : __kfree_skb() skb_release_head_state() sock_wfree() sock_def_write_space() __wake_up_sync_key() __wake_up_common() receiver_wake_function() : Stops here since thread is waiting for an INPUT Reported-by: NChristoph Lameter <cl@linux.com> Signed-off-by: NEric Dumazet <dada1@cosmosbay.com> Signed-off-by: NDavid S.

On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries because old toolchains had bugs where they didn't mark program segments executable that needed to be. For some reason we didn't do this on ppc32 builds. This hadn't been an issue until commit 8d30c14c ("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side effect that we are now enforcing execute permissions to some extent on 32-bit 4xx and Book E processors. This fixes it by defining elf_read_implies_exec on 32-bit to turn on the read-implies-exec behaviour on programs that are sufficiently old that they don't have a PT_GNU_STACK program header.
