* [AVR32] Move setup_bootmem() from mm/init.c to kernel/setup.cHaavard Skinnemoen2007-04-27

* [AVR32] Make I/O access macros work with external devicesHaavard Skinnemoen2007-04-27
| | | | | | | | | | | | | | | | | | | Fix the I/O access macros so that they work with externally connected devices accessed in little-endian mode over any bus width: * Use a set of macros to define I/O port- and memory operations borrowed from MIPS. * Allow subarchitecture to specify address- and data-mangling * Implement at32ap-specific port mangling (with build-time configurable bus width. Only one bus width at a time supported for now.) * Rewrite iowriteN and friends to use write[bwl] and friends (not the __raw counterparts.) This has been tested using pata_pcmcia to access a CompactFlash card connected to the EBI (16-bit bus width.) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Fix NMI handlerHaavard Skinnemoen2007-04-27
| | | | | | | | | | | | | Fix a problem with the NMI handler entry code related to the NMI handler sharing some code with the exception handlers. This is not a good idea because the RSR and RAR registers are not the same, and the NMI handler runs with interrupts masked the whole time so there's no need to check for pending work. Open-code the low-level NMI handling logic instead so that the pt_regs layout is actually correct when the higher-level handler is called. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Clean up exception handling codeHaavard Skinnemoen2007-04-27
| | | | | | | | | | | | | | | * Use generic BUG() handling * Remove some useless debug statements * Use a common function _exception() to send signals or oops when an exception can't be handled. This makes sure init doesn't enter an infinite exception loop as well. Borrowed from powerpc. * Add some basic exception tracing support to the page fault code. * Rework dump_stack(), show_regs() and friends and move everything into process.c * Print information about configuration options and chip type when oopsing Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.

* [AVR32] Change system timer from count-compare to Timer/Counter 0Hans-Christian Egtvedt2007-04-27
| | | | | | | | | | | | | | | | | | | | Due to limitation of the count-compare system timer (not able to count when CPU is in sleep), the system timer had to be changed to use a peripheral timer/counter. The old COUNT-COMPARE code is still present in time.c as weak functions. The new timer is added to the architecture directory. This patch sets up TC0 as system timer The new timer has been tested on AT32AP7000/ATSTK1000 at 100 Hz, 250 Hz, 300 Hz and 1000 Hz.

* | cfq-iosched: fix alias + front merge bugJens Axboe2007-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a really rare and obscure bug in CFQ, that causes a crash in cfq_dispatch_insert() due to rq == NULL. One example of the resulting oops is seen here: http://lkml.org/lkml/2007/4/15/41 Neil correctly diagnosed the situation for how this can happen: if two concurrent requests with the exact same sector number (due to direct IO or aliasing between MD and the raw device access), the alias handling will add the request to the sortlist, but next_rq remains NULL. Read the more complete analysis at: http://lkml.org/lkml/2007/4/25/57 This looks like it requires md to trigger, even though it should potentially be possible to due with O_DIRECT (at least if you edit the kernel and doctor some of the unplug calls). The fix is to move the ->next_rq update to when we add a request to the rbtree. Then we remove the possibility for a request to exist in the rbtree code, but not have ->next_rq correctly updated.

Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

| * | sis900: Allocate rx replacement buffer before rx operationNeil Horman2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sis900 driver appears to have a bug in which the receive routine passes the skbuff holding the received frame to the network stack before refilling the buffer in the rx ring. If a new skbuff cannot be allocated, the driver simply leaves a hole in the rx ring, which causes the driver to stop receiving frames and become non-recoverable without an rmmod/insmod according to reporters. This patch reverses that order, attempting to allocate a replacement buffer first, and receiving the new frame only if one can be allocated. If no skbuff can be allocated, the current skbuf in the rx ring is recycled, dropping the current frame, but keeping the NIC operational.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | noreplacement is dangerous on modern systems because it will not replace the context switch FNSAVE with SSE aware FXSAVE. But other places in the kernel still assume SSE and do FXSAVE and the CPU will then access FXSAVE information with FNSAVE and cause corruption. Easiest way to avoid this is to remove the option. It was mostly for paranoia reasons anyways and alternative()s have been stable for some time. Thanks to Jeremy F. for reporting and helping debug it. Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The listxattr() and getxattr() operations are only protected by a read lock. As a result, if either of these operations run in parallel, a race condition exists where the xattr_root will end up being cached twice, which results in the leaking of a reference and a BUG() on umount. This patch refactors get_xa_root(), __get_xa_root(), and create_xa_root(), into one get_xa_root() function that takes the appropriate locking around the entire critical section.

* | v9fs: don't use primary fid when removing fileLatchesar Ionkov2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v9fs_insert uses v9fs_fid_lookup (which also locks the fid) to get the primary fid associated with the dentry and destroys the v9fs_fid struct after removing the file. If another process called v9fs_fid_lookup on the same dentry, it may wait undefinitely for the fid's lock (as the struct is freed). This patch changes v9fs_remove to use a cloned fid, so the primary fid is not locked and freed.

* | page migration: fix NR_FILE_PAGES accountingChristoph Lameter2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | NR_FILE_PAGES must be accounted for depending on the zone that the page belongs to. If we replace the page in the radix tree then we may have to shift the count to another zone.
