| * | cciss: add cciss_tape_cmds module paramterStephen M. Cameron2011-05-061-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is to allow number of commands reserved for use by SCSI tape drives and medium changers to be adjusted at driver load time via the kernel parameter cciss_tape_cmds, with a default value of 6, and a range of 2 - 16 inclusive. Previously, the driver limited the number of commands which could be queued to the SCSI half of the the driver to only 2. This is to fix the problem that if you had more than two tape drives, you couldn't, for example, erase or rewind them all at the same time. Signed-off-by: Stephen M.

Instead of requiring that they be based in older versions with bugs that have been fixed later in the rc cycle, merge in 2.6.39 final. Also fixes up conflicts in the below files.

* | | | | bitmap, irq: add smp_affinity_list interface to /proc/irqMike Travis2011-05-252-6/+22

Setting smp affinity to cpus 256 to 263 would be: echo 000000ff,00000000,00000000,00000000,00000000,00000000,00000000,00000000 > smp_affinity instead of: echo 256-263 > smp_affinity_list Think about what it looks like for cpus around say, 4088 to 4095. We already have many alternate "list" interfaces: /sys/devices/system/cpu/cpuX/indexY/shared_cpu_list /sys/devices/system/cpu/cpuX/topology/thread_siblings_list /sys/devices/system/cpu/cpuX/topology/core_siblings_list /sys/devices/system/node/nodeX/cpulist /sys/devices/pci***/***/local_cpulist Add a companion interface, smp_affinity_list to use cpu lists instead of cpu maps. This conforms to other companion interfaces where both a map and a list interface exists. This required adding a bitmap_parselist_user() function in a manner similar to the bitmap_parse_user() function.

As we are removing the parameter we can also clean up swapaccount because it doesn't have to accept an empty string anymore (to match noswapaccount) and so we can push = into __setup macro rather than checking "=1" resp.

* | | | | mm: convert mm->cpu_vm_cpumask into cpumask_var_tKOSAKI Motohiro2011-05-251-1/+1

It might lead to reduce cache hit ratio. This patch has two change. 1) Move the place of cpumask into last of mm_struct. Because usually cpumask is accessed only front bits when the system has cpu-hotplug capability 2) Convert cpu_vm_mask into cpumask_var_t. It may help to reduce memory footprint if cpumask_size() will use nr_cpumask_bits properly in future. In addition, this patch change the name of cpu_vm_mask with cpu_vm_mask_var. It may help to detect out of tree cpu_vm_mask users. This patch has no functional change.

This rather unexpected behavior is intentional as per http://gcc.gnu.org/PR28322, so work around it by testing for support of the opposite option (without the no-). Introduce a new Makefile function cc-disable-warning that does this and update two uses of cc-option in the toplevel Makefile.

To avoid a lot of dummy wrapper files that just include the corresponding file in asm-generic provide some basic support in kbuild for this. With the following patch an architecture can maintain a list of files in the file arch/$(ARCH)/include/asm/Kbuild To use a generic file just add: generic-y += <name-of-header-file.h> For each file listed kbuild will generate the necessary wrapper in arch/$(ARCH)/include/generated/asm. When installing userspace headers a wrapper is likewise created. The original inspiration for this came from the unicore32 patchset - although a different method is used. The patch includes several improvements from Arnd Bergmann. Michael Marek contributed Makefile.asm-generic.

There is no good reason to carry custom debugging prints if there is so cool and powerful generic dynamic printk infrastructure, see Documentation/dynamic-debug-howto.txt. With dynamic printks we can switch on/of individual prints, per-file, per-function and per format messages. This means that instead of doing old-fashioned echo 1 > /sys/module/ubifs/parameters/debug_msgs to enable general messages, we can do: echo 'format "UBIFS DBG gen" +ptlf' > control to enable general messages and additionally ask the dynamic printk infrastructure to print process ID, line number and function name. So there is no reason to keep UBIFS-specific crud if there is more powerful generic thing. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

Currently this "force int-the-gaps" debugging feature is a separate test mode. But it is a bit saner to make it to be the "general" self-test check instead. This patch is just a clean-up which should make the debugging code look a bit nicer and easier to use - we have way too many debugging options.
