Hello,
Currently, when perf reports kernel symbols, it tries to look up the

This patch exposes two basic events for Ivytown IMC uncore PMU:

Add a check if crashk_res_low exists just like GART region does. If
crashk_res_low doesn't exist, calling exclude_mem_range is unnecessary.
Meanwhile, since crashk_res_low has been initialized at definition, it's
safe just use "if (crashk_low_res.end)" to check if it's exist. And this
can make it

When cpu hotplug and evaluating ACPI method happen at the same time,
there is a dead lock between ACPICA namespace lock and cpu hotplug lock.
During cpu hotplug, cpu core will call acpi_cpu_soft_notify() to notify
Linux ACPI under cpu hotplug lock. acpi_cpu_soft_notify() calls
acpi_bus_get_device(
Hi,
I posted a 5 patch series to the nfs list last week with the cover letter titled
"nfs_page_group_lock cleanup”, but neglected to mail the wider list.
The might_sleep check was being hit because nfs_page_group_lock with wait=False
called
wait_on_bit_lock (which might sleep). I also had to be

Why? Is that how you submit a patch to be included to the kernel tree?
(hint, the answer is no, and also you should cc: the linux-serial
list...)

When we parse the device tree and allocate platform
devices, the 'name' of the newly-created platform_device
is set to point to the 'name' field of the 'struct device'
embedded within the platform_device. This is dangerous,
because the name of the 'struct device' is dynamically
allocated. Drivers m

hyperv_keyboard invokes serio_interrupt(), which needs a valid serio driver
like atkbd.c.
atkbd.c depends on libps2.c because it invokes ps2_command().
libps2.c depends on i8042.c because it invokes i8042_check_port_owner().
As a result, hyperv_keyboard actually depends on i8042.c.

Hello,
Can somebody please review if the code has anything to improve?
Thanks.

Greg reports that with one of the patches in his queue
there's now an unused variable warning in lnet_parse_ip2nets
for ipaddrs variable.
Apparently the warning is a false positive as in all cases where
lnet_ipaddr_enumerate can return without setting ipaddrs to something
a negative return value is

This commit performs a final tidying of the register map defines, bringing
them to a state that is ready for merging into addi_apci_1564.c when the
time comes. Actions performed include:
*Removes the APCI1564_ADDRESS_RANGE macro, which is no longer needed/used.
*Renames the APCI1564_DIGITAL_OP_{V
Starting with commit 1496e5961113 ("staging: comedi: addi_apci_1564: use
addi_watchdog module to init watchdog subdevice"), this driver uses the
addi_watchdog module to provide support for the watchdog subdevice. Any
remaining watchdog code in-driver can and should be removed.
This will also make
The DO config function served the purpose of configuring the diagnostic
interrupts for the board. As the driver currently does not support
diagnostic interrupts, the digital output subdevice does not need an
insn_config operation and this function can be safely removed.
