* [PATCH] SPI: add PXA2xx SSP SPI DriverStephen Street2006-05-165-0/+1710
| | | | | | | | | | | | | | | | | This driver turns a PXA2xx synchronous serial port (SSP) into a SPI master controller (see Documentation/spi/spi_summary). The driver has the following features: - Support for any PXA2xx SSP - SSP PIO and SSP DMA data transfers. - External and Internal (SSPFRM) chip selects. - Per slave device (chip) configuration. - Full suspend, freeze, resume support.

* [PATCH] SPI: per-transfer overrides for wordsize and clockingImre Deak2006-05-163-14/+77
| | | | | | | | | | | | | | | Some protocols (like one for some bitmap displays) require different clock speed or word size settings for each transfer in an SPI message. This adds those parameters to struct spi_transfer. They are to be used when they are nonzero; otherwise the defaults from spi_device are to be used. The patch also adds a setup_transfer callback to spi_bitbang, uses it for messages that use those overrides, and implements it so that the pure bitbanging code can help resolve any questions about how it should work.

| * [PATCH] Fix pSeries identification in prom_init.cBenjamin Herrenschmidt2006-05-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF trampoline code prom_init.c still needs to identify IBM pSeries (PAPR) machines in order to run some platform specific code on them like instanciating the TCE tables. The code doing that detection was changed recently in 2.6.17 early stages but was done slightly incorrectly. It should be testing for an exact match of "chrp" and it currently tests for anything that begins with "chrp". That means it will incorrectly match with platforms using Maple-like device-trees and have open firmware. This fixes it by using strcmp instead of strncmp to match what the actual platform detection code does.

* | [PATCH] slab: Fix kmem_cache_destroy() on NUMARoland Dreier2006-05-161-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_NUMA set, kmem_cache_destroy() may fail and say "Can't free all objects." The problem is caused by sequences such as the following (suppose we are on a NUMA machine with two nodes, 0 and 1): * Allocate an object from cache on node 0. * Free the object on node 1. The object is put into node 1's alien array_cache for node 0. * Call kmem_cache_destroy(), which ultimately ends up in __cache_shrink(). * __cache_shrink() does drain_cpu_caches(), which loops through all nodes. For each node it drains the shared array_cache and then handles the alien array_cache for the other node. However this means that node 0's shared array_cache will be drained, and then node 1 will move the contents of its alien[0] array_cache into that same shared array_cache. node 0's shared array_cache is never looked at again, so the objects left there will appear to be in use when __cache_shrink() calls __node_shrink() for node 0. So __node_shrink() will return 1 and kmem_cache_destroy() will fail. This patch fixes this by having drain_cpu_caches() do drain_alien_cache() on every node before it does drain_array() on the nodes' shared array_caches. The problem was originally reported by Or Gerlitz <ogerlitz@voltaire.com>.

I guess there was some error on the wireless link, which in turn caused an error condition for the smb filesystem. In the log, smb_file_read reports error=4294966784 (0xfffffe00), which also shows up in the slab dumps, and also is -ERESTARTSYS. Error code 27499 corresponds to 0x6b6b, so the rq_errno field seems to be the only one being set after freeing the slab. In smb_add_request (which is the only place in smbfs where I found ERESTARTSYS), I found the following: if (!timeleft || signal_pending(current)) { /* * On timeout or on interrupt we want to try and remove the * request from the recvq/xmitq. */ smb_lock_server(server); if (!(req->rq_flags & SMB_REQ_RECEIVED)) { list_del_init(&req->rq_queue); smb_rput(req); } smb_unlock_server(server); } [...] if (signal_pending(current)) req->rq_errno = -ERESTARTSYS; I guess that some codepath like smbiod_flush() caused the request to be removed from the queue, and smb_rput(req) be called, without SMB_REQ_RECEIVED being set. This violates an asumption made by the quoted code. Then, the above code calls smb_rput(req) again, the req gets freed, and req->rq_errno = -ERESTARTSYS writes into the already freed slab. As list_del_init doesn't cause an error if called multiple times, that does cause the observed behaviour (freed slab with rq_errno=-ERESTARTSYS). If this observation is correct, the following patch should fix it. I wonder why the smb code uses list_del_init everywhere - using list_del instead would catch such situations by poisoning the next and prev pointers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Even since a previous patch: Fix race between CONFIG_DEBUG_SLABALLOC and modules Sun, 27 Jun 2004 17:55:19 +0000 (17:55 +0000) http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b3db26d31cf21b70e3c1eadc56c179506d8fbe The function symbol_put_addr() will deadlock the kernel. symbol_put_addr() would acquire modlist_lock, then while holding the lock call two functions kernel_text_address() and module_text_address() which also try to acquire the same lock. This deadlocks the kernel of course. This patch changes symbol_put_addr() to not acquire the modlist_lock, it doesn't need it since it never looks at the module list directly. Also, it now uses core_kernel_text() instead of kernel_text_address(). The latter has an additional check for addr inside a module, but we don't need to do that since we call module_text_address() (the same function kernel_text_address uses) ourselves.

| | | | | | | | | | | | | | | | | | An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an overly-zealous PCI quirk to only poke those VIA devices that need it. However, some PCI devices were not included in what I hope is now the full list. Consequently we're failing to run the quirk on all machines which need it, causing IRQ routing failures. This should I hope correct this. Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out and testing the fix.

The test of whether the dentry is mounted if ineffective, for example, if an expire fails then we could wait forever on a non existant expire. The bug was identified by Jeff Moyer. The patch changes autofs4 to wait on expires only as this is all that's needed. If there is no existing wait when autofs4_wait is call with a type of NFY_NONE it delays until either a wait appears or the the expire flag is cleared.
