When load aesni-intel and ghash_clmulni-intel driver,kernel will complain no

The strange information as following:alg: No test for __aes-aesni (__driver-aes-aesni)
alg: No test for __ecb-aes-aesni (__driver-ecb-aes-aesni)
alg: No test for __cbc-aes-aesni (__driver-cbc-aes-aesni)

alg: No test for __ghash (__ghash-pclmulqdqni)
alg: No test for __ghash (cryptd(__ghash-pclmulqdqni))This patch add NULL test entries for these algorithm and driver.

RTC core won't allow wakeup alarms to be set if RTC devices' parent (i.e.
i2c_client or spi_device) isn't wakeup capable.For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via
board info, and if set, I2C core will initialize wakeup capability. For
SPI devices there is no such flag at all.I believe that it's not platform code responsibility to allow or disallow
wakeups, instead, drivers themselves should set the capability if a device
can trigger wakeups.That's what drivers/base/power/sysfs.c says:
* It is the responsibility of device drivers to enable (or disable)
* wakeup signaling as part of changing device power states, respecting
* the policy choices provided through the driver model.I2C and SPI RTC devices send wakeup events via interrupt lines, so we
should set the wakeup capability if IRQ is routed.Ideally we should also check irq for wakeup capability before setting
device's capability, i.e.if (can_irq_wake(irq))
device_set_wakeup_capable(&client->dev, 1);But there is no can_irq_wake() call exist, and it is not that trivial to
implement it for all interrupts controllers and complex/cascaded setups.drivers/base/power/sysfs.c also covers these cases:
* Devices may not be able to generate wakeup events from all power
* states. Also, the events may be ignored in some configurations;
* for example, they might need help from other devices that aren't
* activeSo there is no guarantee that wakeup will actually work, and so I think
there is no point in being pedantic wrt checking IRQ wakeup capability.Signed-off-by: Anton Vorontsov

Daniel Drake noticed a crash in the error path of mmc_attach_sdio(). This
bug is discussed at http://dev.laptop.org/ticket/9707.BUG: unable to handle kernel paging request at 6b6b6c57
IP: [] sdio_remove_func+0x9/0x27
Call Trace:
[] ? mmc_sdio_remove+0x34/0x65
[] ? mmc_attach_sdio+0x217/0x240
[] ? mmc_rescan+0x1a2/0x20f
[] ? worker_thread+0x156/0x1eWe need to accurately track how many SDIO functions have been initialised
(and keep card->sdio_funcs in sync) so that we don't try to remove more
functions than we initialised if we hit the error path in
mmc_attach_sdio().Without this patch if we hit the error path in mmc_attach_sdio() we run
the risk of deferencing invalid memory in sdio_remove_func(), leading to a

Thanks to Roland who pointed out de_thread() issues.
Currently we add sub-threads to ->real_parent->children list. This buys
nothing but slows down do_wait().With this patch ->children contains only main threads (group leaders).
The only complication is that forget_original_parent() should iterate over
sub-threads by hand, and de_thread() needs another list_replace() when it
changes ->group_leader.Henceforth do_wait_thread() can never see task_detached() && !EXIT_DEAD
tasks, we can remove this check (and we can unify do_wait_thread() and
ptrace_do_wait()).This change can confuse the optimistic search in mm_update_next_owner(),
but this is fixable and minor.Perhaps badness() and oom_kill_process() should be updated, but they
should be fixed in any case.Signed-off-by: Oleg Nesterov

rip a subtree away _without_ dissolving connections in it, to be

considerably saner wrt "is the subtree busy" logics, but it's nowhere
