2009-05-15kgdb,i386: use address that SP register points to in the exception frameJason Wessel
The treatment of the SP register is different on x86_64 and i386. This is a regression fix that lived outside the mainline kernel from 2.6.27 to now. The regression was a result of the original merge consolidation of the i386 and x86_64 archs to x86. The incorrectly reported SP on i386 prevented stack tracebacks from working correctly in gdb.

2009-05-15sysrq, intel_fb: fix sysrq g collisionJason Wessel
Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a regression where you cannot use sysrq 'g' to enter kgdb. The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

2009-05-13Revert "Ignore madvise(MADV_WILLNEED) for hugetlbfs-backed regions"Linus Torvalds
This reverts commit a425a638c858fd10370b573bde81df3ba500e271. Now that the previous commit removed the "readpage" actor for hugetlb files, read-ahead will no longer mess up the mapping, and there's no longer any reason to treat hugetlbfs mappings specially.

2009-05-13Remove implementation of readpage from the hugetlbfs_aopsMel Gorman
The core VM assumes the page size used by the address_space in inode->i_mapping is PAGE_SIZE but hugetlbfs breaks this assumption by inserting pages into the page cache at offsets the core VM considers unexpected. This would not be a problem except that hugetlbfs also provide a ->readpage implementation. As it exists, the core VM can assume the base page size is being used, allocate pages on behalf of the filesystem, insert them into the page cache and call ->readpage to populate them. These pages are the wrong size and at the wrong offset for hugetlbfs causing confusion. This patch deletes the ->readpage implementation for hugetlbfs on the grounds the core VM should not be allocating and populating pages on behalf of hugetlbfs. There should be no existing users of the ->readpage implementation so it should not cause a regression.

This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination). If respective flag is not set, the driver assumes dma-unmapping as page.

2009-05-11xtensa: Fix linker script to include .literal sectionsChris Zankel
Fix resembles implementation from Marc Gauthier and Piet Denaly: In the Xtensa architecture, assembly generates literals which must always precede the code (the L32R instruction that loads them only uses negative PC-relative offsets). For any *.text section, literals are placed in a corresponding *.literal section. The linker script (vmlinux.lds) must place these in the correct order. It must also combine them, when the *.text section can be larger than L32R's 256 kB range. For example, this doesn't work: *(.literal) *(.text) because L32R instructions at the end of .text can't reach the literals. The linker can solve this if they are combined in parentheses, like this: *(.literal .text) because it is now allowed mix literals in .text to bring them in range. None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT and INIT_TEXT. To avoid replicating the logic of that header file, we instead post-process the generated linker script to convert *(xxx.text) to *(xxx.literal xxx.text) for the following text sections: .text .ref.text .*init.text .*exit.text .text.* using a sed script. To do this we must override the default rule for vmlinux.lds (see scripts/Makefile.build and the top-level Makefile) to insert this extra step.

2009-05-11xtensa: always use correct stack pointer for stack tracesJohannes Weiner
Commit '28a0ce7 xtensa: use correct stack pointer for stack traces' changed the stack tracer from always reading the stack pointer register to always using the saved value in the task descriptor. The author was too dense to consider the fact that the saved stack value is stale for a running process und thus unusable for 'current'. What we do now is to use the stack pointer register (a1) for when the task is unknown - we can't help it then - or when the task is 'current'. For everything else use the saved stack pointer value contained in the task descriptor. Signed-off-by: Johannes Weiner <jw@emlix.com> Signed-off-by: Chris Zankel <chris@zankel.net>
