2017-06-08rcu: Remove SPARSE_RCU_POINTER Kconfig optionPaul E. McKenney1-6/+0
The sparse-based checking for non-RCU accesses to RCU-protected pointers has been around for a very long time, and it is now the only type of sparse-based checking that is optional. This commit therefore makes it unconditional. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Fengguang Wu <fengguang.wu@intel.com>

2017-05-16kgdb.rst: Adjust ReST markupsMauro Carvalho Chehab1-255/+232
The automatic conversion didn't work too well for this file. It added weird html blocks inside it, and did some weird things for literals. Manually fix it, in order to present a nice display at html/pdf outputs. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2017-03-09scripts/spelling.txt: add "disble(d)" pattern and fix typo instancesMasahiro Yamada1-1/+1
Fix typos and add the following to the scripts/spelling.txt: disble||disable disbled||disabled I kept the TSL2563_INT_DISBLED in /drivers/iio/light/tsl2563.c untouched. The macro is not referenced at all, but this commit is touching only comment blocks just in case.

2017-02-15Improve sparse documentationMatthew Wilcox1-0/+6
Add documentation of -DCONFIG_SPARSE_RCU_POINTER. I started to add documentation of -D__CHECK_ENDIAN__ as well, but discovered I'm too late; that's now enabled by default. Signed-off-by: Matthew Wilcox <mawilcox@microsoft.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2016-10-11mm: kmemleak: avoid using __va() on addresses that don't have a lowmem mappingCatalin Marinas1-0/+9
Some of the kmemleak_*() callbacks in memblock, bootmem, CMA convert a physical address to a virtual one using __va(). However, such physical addresses may sometimes be located in highmem and using __va() is incorrect, leading to inconsistent object tracking in kmemleak. The following functions have been added to the kmemleak API and they take a physical address as the object pointer. They only perform the corresponding action if the address has a lowmem mapping: kmemleak_alloc_phys kmemleak_free_part_phys kmemleak_not_leak_phys kmemleak_ignore_phys The affected calling places have been updated to use the new kmemleak API.
