2006-03-23[PATCH] I2C: i2c-piix4: Add Broadcom HT-1000 supportMartin Devera
Add Broadcom HT-1000 south bridge's PCI ID to i2c-piix driver. Note that at least on Supermicro H8SSL it uses non-standard SMBHSTCFG = 3 and standard values like 0 or 9 causes hangup.

2006-03-23[PATCH] w83781d: Don't reset the chip by defaultJean Delvare

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: Jean Delvare <khali@linux-fr.org>

2006-03-23[PATCH] hwmon: Use attribute arrays in f71805fJean Delvare
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.

2006-03-23[PATCH] reduce size of bio mempoolsBenjamin LaHaise
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.

2006-03-23[PATCH] __GENERIC_PER_CPU changesEric Dumazet
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.

2006-03-23[PATCH] more for_each_cpu() conversionsAndrew Morton
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.

2006-03-23[PATCH] Only allocate percpu data for possible CPUsEric Dumazet
percpu_data blindly allocates bootmem memory to store NR_CPUS instances of cpudata, instead of allocating memory only for possible cpus.

2006-03-23[PATCH] get_empty_filp tweaks, inline epoll_init_file()Benjamin LaHaise
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.

2006-03-23[PATCH] pause_on_oops command line optionAndrew Morton
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.
