Document the individual alarm and beep bits of the w83781d driver. Ideally we would offer a chip-independant interface for them, but until it's done, it's only fair that we document the current interface. Signed-off-by:

Add support for the Winbond W83687THF chip to the w83627hf hardware monitoring driver. This new chip is almost similar to the already supported W83627THF chip, except for VID and a few other minor changes. Signed-off-by:

This patch refactors SENSOR_DEVICE_ATTR_2 macro, following pattern set by SENSOR_ATTR. First it creates a new macro SENSOR_ATTR_2() which expands to an initialization expression, then it uses that in SENSOR_DEVICE_ATTR_2, which declares and initializes a struct sensor_device_attribute_2.

scx200_acb is only useful on a few Geode-based systems, and won't compile on non-x86 systems due to the lack of asm/msr.h, as reported by Andrew Morton. Thus, we should make that driver depend on X86. Signed-off-by: -

Convert the f71805f driver to use arrays of attributes. This shrinks the compiled module from 12.0 kB to 9.6 kB. We certainly should do the same for as many hardware monitoring drivers as possible. This, together with a nice chip design by Fintek, makes this driver very small, both in terms of number of lines of code and memory consumption. Signed-off-by:

This patch refactors SENSOR_DEVICE_ATTR macro. First it creates a new macro SENSOR_ATTR() which expands to an initialization expression, then it uses that in SENSOR_DEVICE_ATTR, which declares and initializes a struct sensor_device_attribute. IOW, SENSOR_ATTR() imitates __ATTR() in include/linux/device.h. Signed-off-by:

The biovec default mempool limit of 256 entries results in over 3MB of RAM being permanently pinned, even on systems with only 128MB of RAM. Since mempool tries to allocate from the system pool first, it makes sense to reduce the size of the mempool fallbacks to a more reasonable limit of 1-5 entries -- enough for the system to be able to make progress even under load.

Now CONFIG_DEBUG_INITDATA is in, initial percpu data [__per_cpu_start,__per_cpu_end] can be declared as a redzone, and invalid accesses after boot can be detected, at least for i386. We can let non possible cpus percpu data point to this 'redzone' instead of NULL . NULL was not a good choice because part of [0..32768] memory may be readable and invalid accesses may happen unnoticed. If CONFIG_DEBUG_INITDATA is not defined, each non possible cpu points to the initial percpu data (__per_cpu_offset[cpu] == 0), thus invalid accesses wont be detected/crash. This patch also moves __per_cpu_offset[] to read_mostly area to avoid false sharing. Signed-off-by:

When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros. Cc: Mikael Starvik <starvik@axis.com> Cc: David Howells <dhowells@redhat.com> Acked-by:

percpu_data blindly allocates bootmem memory to store NR_CPUS instances of cpudata, instead of allocating memory only for possible cpus. This patch saves ram, allocating num_possible_cpus() (instead of NR_CPUS) instances. Signed-off-by:

Eliminate a handful of cache references by keeping current in a register instead of reloading (helps x86) and avoiding the overhead of a function call. Inlining eventpoll_init_file() saves 24 bytes. Also reorder file initialization to make writes occur more sequentially. Signed-off-by:

Without branch hints, the very unlikely chance of the loop repeating due to cmpxchg failure is unrolled with gcc-4 that I have tested. Improve this for architectures with a native cas/cmpxchg. llsc archs should try to implement this natively. Signed-off-by:

Attempt to fix the problem wherein people's oops reports scroll off the screen due to repeated oopsing or to oopses on other CPUs. If this happens the user can reboot with the `pause_on_oops=<seconds>' option. It will allow the first oopsing CPU to print an oops record just a single time. Second oopsing attempts, or oopses on other CPUs will cause those CPUs to enter a tight loop until the specified number of seconds have elapsed. The patch implements the infrastructure generically in the expectation that architectures other than x86 will find it useful. Cc: Dave Jones <davej@codemonkey.org.uk> Signed-off-by:
