* davinci: da8xx: Add base DA830/OMAP-L137 SoC supportMark A. Greer2009-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The da830/omap l137 is a new SoC from TI that is similar to the davinci line. Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel. Additional generalizations for future SoCs in the da8xx family done by Sudhakar Rajashekhara and Sekhar Nori.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - restructure to support multiple channel controllers by using additional struct resources for each CC - interface changes visible to EDMA clients Introduce macros to build IDs from controller and channel number, and to extract them. Modify the edma_alloc_slot function to take an extra argument for the controller. Also update ASoC drivers to use API. ASoC changes Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> - Move queue related mappings to dm<soc>.c EDMA in DM355 and DM644x has two transfer controllers while DM646x has four transfer controllers. Moving the queue to tc mapping and queue priority mapping to dm<soc>.c will be helpful to probe these mappings from platform device so that the machine_is_* testing will be avoided. - add channel mapping logic Channel mapping logic is introduced in dm646x EDMA. This implies that there is no fixed association for a channel number to a parameter entry number. In other words, using the DMA channel mapping registers (DCHMAPn), a PaRAM entry can be mapped to any channel. While in the case of dm644x and dm355 there is a fixed mapping between the EDMA channel and Param entry number.

* Re-introduce page mapping check in mark_buffer_dirty()Linus Torvalds2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit a8e7d49aa7be728c4ae241a75a2a124cdcabc0c5 ("Fix race in create_empty_buffers() vs __set_page_dirty_buffers()"), I removed a test for a NULL page mapping unintentionally when some of the code inside __set_page_dirty() was moved to the callers. That removal generally didn't matter, since a filesystem would serialize truncation (which clears the page mapping) against writing (which marks the buffer dirty), so locking at a higher level (either per-page or an inode at a time) should mean that the buffer page would be stable. And indeed, nothing bad seemed to happen. Except it turns out that apparently reiserfs does something odd when under load and writing out the journal, and we have a number of bugzilla entries that look similar: http://bugzilla.kernel.org/show_bug.cgi?id=13556 http://bugzilla.kernel.org/show_bug.cgi?id=13756 http://bugzilla.kernel.org/show_bug.cgi?id=13876 and it looks like reiserfs depended on that check (the common theme seems to be "data=journal", and a journal writeback during a truncate). I suspect reiserfs should have some additional locking, but in the meantime this should get us back to the pre-2.6.29 behavior.

* | | x86: don't call '->send_IPI_mask()' with an empty maskLinus Torvalds2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in 83d349f35e1ae72268c5104dbf9ab2ae635425d4 ("x86: don't send an IPI to the empty set of CPU's"), some APIC's will be very unhappy with an empty destination mask. That commit added a WARN_ON() for that case, and avoided the resulting problem, but didn't fix the underlying reason for why those empty mask cases happened. This fixes that, by checking the result of 'cpumask_andnot()' of the current CPU actually has any other CPU's left in the set of CPU's to be sent a TLB flush, and not calling down to the IPI code if the mask is empty. The reason this started happening at all is that we started passing just the CPU mask pointers around in commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), and when we did that, the cpumask was no longer thread-local. Before that commit, flush_tlb_mm() used to create it's own copy of 'mm->cpu_vm_mask' and pass that copy down to the low-level flush routines after having tested that it was not empty. But after changing it to just pass down the CPU mask pointer, the lower level TLB flush routines would now get a pointer to that 'mm->cpu_vm_mask', and that could still change - and become empty - after the test due to other CPU's having flushed their own TLB's. See http://bugzilla.kernel.org/show_bug.cgi?id=13933 for details.

* | | Make bitmask 'and' operators return a result codeLinus Torvalds2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When 'and'ing two bitmasks (where 'andnot' is a variation on it), some cases want to know whether the result is the empty set or not. In particular, the TLB IPI sending code wants to do cpumask operations and determine if there are any CPU's left in the final set. So this just makes the bitmask (and cpumask) functions return a boolean for whether the result has any bits set.

So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.

This turns out to be a bug brought by an -rc1 patch ("nilfs2: simplify remaining sget() use"). In the patch, a new "put resource" function, nilfs_put_sbinfo() was introduced to delay freeing nilfs_sb_info struct. But the nilfs_put_sbinfo() mistakenly used atomic_dec_and_test() function to check the reference count, and it caused the nilfs_sb_info was freed when user mounted a snapshot twice. This bug also suggests there was unseen memory leak in usual mount /umount operations for nilfs. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'ns_cno' of structure 'the_nilfs' must be protected from segment writer, in other words, the caller of nilfs_get_checkpoint should hold read lock for nilfs->ns_segctor_sem. This patch adds the lock/unlock operations in nilfs_attach_checkpoint() when calling nilfs_cpfile_get_checkpoint().
