2013-04-02Fix example error_injection_toolXie XiuQi
I got a "sched_setaffinity:: Invalid argument" error when using err_injection_tool to inject error on a system with over 32 cpus. Error information when injecting an error on a system with over 32 cpus: $ ./err_injection_tool -i /sys/devices/system/cpu/cpu0/err_inject//err_type_info Begine at Tue Mar 26 11:20:08 2013 Configurations: On cpu32: loop=10, interval=5(s) err_type_info=4101,err_struct_info=95 Error sched_setaffinity:: Invalid argument All done This because there is overflow when calculating the cpumask: the type of (1<<k) is int, while mask[j] is unsigned long. When k > 31, (1<<k) is truncated to ZERO, resulting in a unexpected cpumask. Signed-off-by: Xie XiuQi <xiexiuqi@huawei.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2010-08-04Documentation: update broken web addresses.Justin P. Mattock
Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

2008-08-12docsrc: build Documentation/ sourcesRandy Dunlap
Currently source files in the Documentation/ sub-dir can easily bit-rot since they are not generally buildable, either because they are hidden in text files or because there are no Makefile rules for them. This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds). Built (using cross-tools) for x86-64, i386, alpha, ia64, sparc32, sparc64, powerpc, sh, m68k, & mips.

2007-07-11[IA64] prevent MCA when performing MMIO mmap to PCI config spaceAlex Chiang
Example memory map (HP rx7640 with 'default' acpiconfig setting, VGA disabled): 0x00000000 - 0x3FFFBFFF supports only WB (cacheable) access If a user attempts to perform an MMIO mmap (using the PCIIOC_MMAP_IS_MEM ioctl) to PCI config space (like mmap'ing and accessing memory at 0xA0000), we will MCA because the kernel will attempt to use a mapping with the UC attribute. So check the memory attribute in kern_mmap and the EFI memmap. If WC is requested, and WC or UC access is supported for the region, allow it. Otherwise, use the same attribute the kernel uses.

2006-05-08[IA64] rework memory attribute aliasingBjorn Helgaas
This closes a couple holes in our attribute aliasing avoidance scheme: - The current kernel fails mmaps of some /dev/mem MMIO regions because they don't appear in the EFI memory map. This keeps X from working on the Intel Tiger box. - The current kernel allows UC mmap of the 0-1MB region of /sys/.../legacy_mem even when the chipset doesn't support UC access. This causes an MCA when starting X on HP rx7620 and rx8620 boxes in the default configuration. There's more detail in the Documentation/ia64/aliasing.txt file this adds, but the general idea is that if a region might be covered by a granule-sized kernel identity mapping, any access via /dev/mem or mmap must use the same attribute as the identity mapping. Otherwise, we fall back to using an attribute that is supported according to the EFI memory map, or to using UC if the EFI memory map doesn't mention the region.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
