* | xen: disable split pte locks for nowJeremy Fitzhardinge2007-10-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When pinning and unpinning pagetables, we must protect them against being used by other CPUs, lest they see the pagetable in an intermediate read-only-but-not-pinned state. When using split pte locks, doing this properly would require taking all the pte locks for the pagetable while pinning, but this may overflow the PREEMPT_BITS part of the preempt counter if the process has mapped more than about 512M of memory. However, failing to take the pte locks causes write-protect faults when the pageout code is trying to clear the Access bit on a pte which is part of a freshy created and still being pinned process after fork. This is a short-term fix until the problem is solved properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI-E slot on T1000 connects directly to the Fire PCI chip with no intervening bridges visible in the OBP tree. Unfortunately the bus numbering of the device in that slot is different (2) from the PCI host controller (0), and thus the pci_bus_{read,write}_config_*() calls don't work out. Complicating things further the Fire PCI controller has no config space it responds to either. For now treat this case specially so that devices in the slot work. Longer term we need to perhaps cons up a dummy bridge between the Fire and the PCI-E slot so that the bus hierarchy is complete inside of the kernel and thus the bus numbering all works out right.

* | | Remove unnecessary cast in prefetch()Serge Belyshev2007-10-051-1/+1

But in standard C, it is invalid to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and note #84). prefetch() has a memory reference for its argument. Newer gcc versions (4.3 and above) will use that to conclude that "x" argument is non-null and thus wreaking havok everywhere prefetch() was inlined. Fixed by removing cast and changing asm constraint. [ It seems in theory gcc 4.2 could miscompile this too; although no cases known. In 2.6.24 we should probably switch to __builtin_prefetch() instead, but this is a simpler fix for now. -- AK ] Signed-off-by: Serge Belyshev <belyshev@depni.sinp.msu.ru> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gurudas Pai reports kernel BUG at arch/i386/mm/highmem.c:15! below sys_remap_file_pages, while running Oracle database test on x86 in 6GB RAM: kunmap thinks we're in_interrupt because the preempt count has wrapped. That's because __do_fault expected to unmap page_table, but one of its two callers do_nonlinear_fault already unmapped it: let do_linear_fault unmap it first too, and then there's no need to pass the page_table arg down. Why have we been so slow to notice this? Probably through forgetting that the mapping_cap_account_dirty test means that sys_remap_file_pages nowadays only goes the full nonlinear vma route on a few memory-backed filesystems like ramfs, tmpfs and hugetlbfs. [ It also depends on CONFIG_HIGHPTE, so it becomes even harder to trigger in practice. Many who have need of large memory have probably migrated to x86-64..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the case where the source is not aligned modulo 8 we don't use load-twins to suck the data in and this kills performance since normal loads allocate in the L1 cache (unlike load-twin) and thus big memcpys swipe the entire L1 D-cache. We need to allocate a register window to implement this properly, but that actually simplifies a lot of things as a nice side-effect. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | argv and envp are pointers to u32's in userspace, so don't try to put_user() a NULL to them. Aparently gcc-4.2.x now warns about this, and since we use -Werror for arch/sparc64 code, this breaks the build. Signed-off-by: David S. Miller <davem@davemloft.net>
