| * Improve vmlinux.lds.h support for arch specific linker scriptsSam Ravnborg2009-06-091-7/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support alingment of the individual architecture specific linker scripts provide a set of general definitions in vmlinux.lds.h With these definitions applied the diverse linekr scripts can be reduced in line count and their readability are improved - IMO. A sample linker script is included to give the preferred order of the sections for the architectures that do not have any special requirments. These definitions are also a first step towards eventual support for -ffunction-sections. The definitions makes it much easier to do a global renaming of section names - but the main purpose is to clean up the linker scripts. Tim Aboot has provided a lot of inputs to improve the definitions - all faults are mine. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Tim Abbott <tabbott@mit.edu>

| * | IB/mlx4: Add strong ordering to local inval and fast reg work requestsJack Morgenstein2009-06-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ConnectX Programmer's Reference Manual states that the "SO" bit must be set when posting Fast Register and Local Invalidate send work requests. When this bit is set, the work request will be executed only after all previous work requests on the send queue have been executed. (If the bit is not set, Fast Register and Local Invalidate WQEs may begin execution too early, which violates the defined semantics for these operations) This fixes the issue with NFS/RDMA reported in <http://lists.openfabrics.org/pipermail/general/2009-April/059253.html> Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Cc: <stable@kernel.org> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * | mlx4_core: Add module parameter for number of MTTs per segmentEli Cohen2009-05-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current MTT allocator uses kmalloc() to allocate a buffer for its buddy allocator, and thus is limited in the amount of MTT segments that it can control. As a result, the size of memory that can be registered is limited too. This patch uses a module parameter to control the number of MTT entries that each segment represents, allowing more memory to be registered with the same number of segments.

The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

Simple NOMMU architectures can use it out of the box, but a minimal __access_ok() should be added there as well. Cc: Michal Simek <monstr@monstr.eu> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The two files cache.h and cacheflush.h can possibly also be used by architectures that have an MMU but never require flushing the cache or have cache lines larger than 32 bytes.

Modern architectures live happily without these specific interfaces, but a few definitions from these headers keep getting used in common code. The new generic headers are what most architectures use anyway nowadays, just implementing the minimal definitions.

This makes get_rtc_ss call the real set_rtc_time to let architectures define their own version. The change should fix the "Extended RTC operation" on Alpha, which uses the incorrect get_rtc_ss call. It also allows PowerPC to use the asm-generic/rtc.h file in the future.

This version of unistd.h has gone through intensive review to make sure that by default it only enables syscalls that do not already have a more featureful replacement. It is modeled after the x86-64 version of unistd.h, which unifies the syscall number definition and the actual system call table in a single file, in order to keep them synchronized much more easily. This first version still keeps legacy system call definitions around, guarded by various #ifdefs, and with numbers larger than 1024. The idea behind this is to make it easier for new architectures to transition from a full list to the reduced set. In particular, the new microblaze architecture that should migrate to using the generic ABI headers can at least use an existing uClibc source tree without major rewrites during the conversion.

To make it easier for future architectures, provide a sane generic version here. In cases where multiple architectures already use identical code, I used the most common version. In cases like stat.h that are more or less broken everywhere, I provide a version that is meant to be ideal for new architectures.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.
