2009-06-20x86: don't use 'access_ok()' as a range check in get_user_pages_fast()Linus Torvalds1-2/+7
It's really not right to use 'access_ok()', since that is meant for the normal "get_user()" and "copy_from/to_user()" accesses, which are done through the TLB, rather than through the page tables. Why? access_ok() does both too few, and too many checks. Too many, because it is meant for regular kernel accesses that will not honor the 'user' bit in the page tables, and because it honors the USER_DS vs KERNEL_DS distinction that we shouldn't care about in GUP. And too few, because it doesn't do the 'canonical' check on the address on x86-64, since the TLB will do that for us. So instead of using a function that isn't meant for this, and does something else and much more complicated, just do the real rules: we don't want the range to overflow, and on x86-64, we want it to be a canonical low address (on 32-bit, all addresses are canonical).

Commit b696fdc259f0d94348a9327bed352fac44d4883d ("sparc64: Defer cpu_data() setup until end of per-cpu data initialization.") broke bootup for UP builds because the cpu_data() initialization only occurs in setup_per_cpu_areas() which is never compiled in nor called in UP builds. Fix this up by calling the setups directly from init_64.c when non-SMP.

2009-06-19gcov: add gcov profiling infrastructurePeter Oberparleiter1-0/+2
Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

2009-06-17[IA64] Convert ia64 to use int-ll64.hMatthew Wilcox33-204/+206
It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

2009-06-17MIPS: Allow CPU specific overriding of CP0 hwrena impl bits.David Daney2-1/+5
Some CPUs have implementation dependent rdhwr registers. Allow them to be enabled on a per CPU basis. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-06-17MIPS: Kconfig Add SYS_SUPPORTS_HUGETLBFS and enable it for some systems.David Daney1-0/+11
Add new kconfig variables SYS_SUPPORTS_HUGETLBFS and CPU_SUPPORTS_HUGEPAGES. They are enabled for systems that are known to support huge pages. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
