* Merge branch 'generic-string-functions'Linus Torvalds2012-05-2723-490/+259
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes <asm/word-at-a-time.h> actually live up to its promise of allowing architectures to help tune the string functions that do their work a word at a time. David had already taken the x86 strncpy_from_user() function, modified it to work on sparc, and then done the extra work to make it generically useful. This then expands on that work by making x86 use that generic version, completing the circle. But more importantly, it fixes up the word-at-a-time interfaces so that it's now easy to also support things like strnlen_user(), and pretty much most random string functions. David reports that it all works fine on sparc, and Jonas Bonn reported that an earlier version of this worked on OpenRISC too. It's pretty easy for architectures to add support for this and just replace their private versions with the generic code. * generic-string-functions: sparc: use the new generic strnlen_user() function x86: use the new generic strnlen_user() function lib: add generic strnlen_user() function word-at-a-time: make the interfaces truly generic x86: use generic strncpy_from_user routine

| * lib: add generic strnlen_user() functionLinus Torvalds2012-05-263-0/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new generic optimized strnlen_user() function that uses the <asm/word-at-a-time.h> infrastructure to portably do efficient string handling. In many ways, strnlen is much simpler than strncpy, and in particular we can always pre-align the words we load from memory. That means that all the worries about alignment etc are a non-issue, so this one can easily be used on any architecture. You obviously do have to do the appropriate word-at-a-time.h macros.

| * word-at-a-time: make the interfaces truly genericLinus Torvalds2012-05-266-53/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the interfaces in <asm/word-at-a-time.h> to be a bit more complicated, but a lot more generic. In particular, it allows us to really do the operations efficiently on both little-endian and big-endian machines, pretty much regardless of machine details. For example, if you can rely on a fast population count instruction on your architecture, this will allow you to make your optimized <asm/word-at-a-time.h> file with that. NOTE! The "generic" version in include/asm-generic/word-at-a-time.h is not truly generic, it actually only works on big-endian. Why? Because on little-endian the generic algorithms are wasteful, since you can inevitably do better. The x86 implementation is an example of that. (The only truly non-generic part of the asm-generic implementation is the "find_zero()" function, and you could make a little-endian version of it. And if the Kbuild infrastructure allowed us to pick a particular header file, that would be lovely) The <asm/word-at-a-time.h> functions are as follows: - WORD_AT_A_TIME_CONSTANTS: specific constants that the algorithm uses. - has_zero(): take a word, and determine if it has a zero byte in it. It gets the word, the pointer to the constant pool, and a pointer to an intermediate "data" field it can set. This is the "quick-and-dirty" zero tester: it's what is run inside the hot loops. - "prep_zero_mask()": take the word, the data that has_zero() produced, and the constant pool, and generate an *exact* mask of which byte had the first zero. This is run directly *outside* the loop, and allows the "has_zero()" function to answer the "is there a zero byte" question without necessarily getting exactly *which* byte is the first one to contain a zero. If you do multiple byte lookups concurrently (eg "hash_name()", which looks for both NUL and '/' bytes), after you've done the prep_zero_mask() phase, the result of those can be or'ed together to get the "either or" case. - The result from "prep_zero_mask()" can then be fed into "find_zero()" (to find the byte offset of the first byte that was zero) or into "zero_bytemask()" (to find the bytemask of the bytes preceding the zero byte). The existence of zero_bytemask() is optional, and is not necessary for the normal string routines. But dentry name hashing needs it, so if you enable DENTRY_WORD_AT_A_TIME you need to expose it. This changes the generic strncpy_from_user() function and the dentry hashing functions to use these modified word-at-a-time interfaces. This gets us back to the optimized state of the x86 strncpy that we lost in the previous commit when moving over to the generic version. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
| * x86: use generic strncpy_from_user routineLinus Torvalds2012-05-263-97/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic strncpy_from_user() is not really optimal, since it is designed to work on both little-endian and big-endian. And on little-endian you can simplify much of the logic to find the first zero byte, since little-endian arithmetic doesn't have to worry about the carry bit propagating into earlier bytes (only later bytes, which we don't care about). But I have patches to make the generic routines use the architecture- specific <asm/word-at-a-time.h> infrastructure, so that we can regain the little-endian optimizations. But before we do that, switch over to the generic routines to make the patches each do just one well-defined thing. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

I tried hard to make sure the bindings are proper. In more complicated cases, I requested acks from people having more experience with them than me. That took a bit of extra time and also some time went into discussions with developers about what bindings are and what not. I have the feeling that the workflow with bindings should be improved to scale better. I will spend some more thought on this... - i2c-muxes are succesfully used meanwhile, so we dropped EXPERIMENTAL for them and renamed the drivers to a standard pattern to match the rest of the subsystem. They can also be used with devicetree now. - ixp2000 was removed since the whole platform goes away. - cleanups (strlcpy instead of strcpy, NULL instead of 0) - The rest is typical driver fixes I assume. All patches have been in linux-next at least since v3.4-rc6." Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the same patch already having come in through the arm/soc trees, with additional patches on top of it. * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (35 commits) i2c: davinci: Free requested IRQ in remove i2c: ocores: register OF i2c devices i2c: tegra: notify transfer-complete after clearing status.

| * | i2c/of: Automatically populate i2c mux busses from device tree data.David Daney2012-05-122-0/+83

This patch adds a common code to the i2c mux framework to have the mux sub-busses be populated by the of_i2c_register_devices() too. If the mux device has an of_node, we populate the sub-bus' of_node so that the subsequent call to of_i2c_register_devices() will find the corresponding devices. It seemed better to put this logic in i2c_add_mux_adapter() rather than the individual mux drivers, as they will all probably want to do the same thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The STM SPEAr platform can only access the i2c controller register via 16bit read/write functions. This patch adds support to automatically detect this 16bit access mode. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 488bf314b ("i2c: Allow i2c_add_numbered_adapter() to assign a bus id") reworked i2c_add_numbered_adapter() to call i2c_add_adapter() if requested bus was -1. This allows to simplify driver's initialization procedure by using just one function for static and dynamic adapter id registration. This patch updates few more drivers (missed out in original patch) to use this functionality.

This cleanup is a step in the move towards multiplatform kernels since it would reduce the need to check for compatible platforms in each and every initcall."
