2007-10-31[SPARC64]: Fix build with CONFIG_NET disabled.David S. Miller
We can't export verify_compat_iovec when CONFIG_NET is disabled, and consequently the Solaris compat module should also depend upon CONFIG_NET. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-31[SPARC64]: Fix build failure when CONFIG_BUG is disabled.David S. Miller
When CONFIG_BUG is turned off, the standard trick of: switch (x) { case X: ... case Y: ... default: BUG(); }; to mark impossible cases does not work because BUG() evalutes to nothing and thus GCC just sees a fallthrough code path. Add an explicit KERN_ERR log message and a do_exit() to trap this case. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-29Revert "x86_64: allocate sparsemem memmap above 4G"Linus Torvalds
This reverts commit 2e1c49db4c640b35df13889b86b9d62215ade4b6. First off, testing in Fedora has shown it to cause boot failures, bisected down by Martin Ebourne, and reported by Dave Jobes. So the commit will likely be reverted in the 2.6.23 stable kernels. Secondly, in the 2.6.24 model, x86-64 has now grown support for SPARSEMEM_VMEMMAP, which disables the relevant code anyway, so while the bug is not visible any more, it's become invisible due to the code just being irrelevant and no longer enabled on the only architecture that this ever affected.

2007-10-29[MIPS] MT: Fix bug in multithreaded kernels.Ralf Baechle
When GDB writes a breakpoint into address area of inferior process the kernel needs to invalidate the modified memory in the inferior which is done by calling flush_cache_page which in turns calls r4k_flush_cache_page and local_r4k_flush_cache_page for VSMP or SMTC kernel via r4k_on_each_cpu(). As the VSMP and SMTC SMP kernels for 34K are running on a single shared caches it is possible to get away without interprocessor function calls. This optimization is implemented in r4k_on_each_cpu, so local_r4k_flush_cache_page is only ever called on the local CPU. This is where the following code in local_r4k_flush_cache_page() strikes: /* * If ownes no valid ASID yet, cannot possibly have gotten * this page into the cache. */ if (cpu_context(smp_processor_id(), mm) == 0) return; On VSMP and SMTC had a function of cpu_context() for each CPU(TC). So in case another CPU than the CPU executing local_r4k_cache_flush_page has not accessed the mm but one of the other CPUs has there may be data to be flushed in the cache yet local_r4k_cache_flush_page will falsely return leaving the I-cache inconsistent for the breakpoint. While the issue was discovered with GDB it also exists in local_r4k_flush_cache_range() and local_r4k_flush_cache(). Fixed by introducing a new function has_valid_asid which on MT kernels returns true if a mm is active on any processor in the system. This is relativly expensive since for memory acccesses in that loop cache misses have to be assumed but it seems the most viable solution for 2.6.23 and older -stable kernels.

Contrary to the belief of some, the R3000 and related processors did have caches, both a data and an instruction cache. Here is an implementation of r3k_flush_cache_page(), which is the processor-specific back-end for flush_cache_range(), done according to the spec in Documentation/cachetlb.txt.

2007-10-29[MIPS] Add len and addr validation for MAP_FIXED mappings.David Daney
Mmap with MAP_FIXED was not validating the addr and len parameters. This leads to the failure of GCC's gcc.c-torture/execute/loop-2[fg].c testcases when using the o32 ABI on a 64 bit kernel. These testcases try to mmap 65536 bytes at 0x7fff8000 and then access all the memory. In 2.6.18 and 2.6.23.1 (and likely other versions as well) the kernel maps the requested memory, but since half of it is above 0x80000000 a SIGBUS is generated when it is accessed. This patch moves the len validation above the MAP_FIXED processing so that it is always validated. It also adds validation to the addr parameter for MAP_FIXED mappings.
