Fix up some misc warnings: include module.h in cache.c since it uses EXPORT_SYMBOL(), fix printk format arg in sn_serial.c.

The note_interrupt() code is racy for per-CPU irqs and causes severe performance problems due to cache-line bouncing on large SMPs. Just don't call it for that case.

[PATCH] ia64: mca.c cleanup - Delete all record printing code, moved to salinfo_decode in user space
-
Keith Owens authored
Port the ia64 mca.c clean up patches from 2.4.25-pre8 to 2.6.2-rc2. The following 6 patches do :- 1 Avoid deadlock when using printk() for MCA and INIT records. 2 Delete all record printing code, moved to salinfo_decode in user space. 3 Mark variables and functions static where possible. 4 Delete dead variables and functions. 5 Reorder to remove the need for forward declarations and to consolidate related code. 6 Bjorn's printk cleanup. Altogether they shrink mca.c from 2432 to 1339 lines and make it much more readable. The only functional change is the removal of any attempt to print the CMC/CPE/MCA/INIT record contents in the kernel plus the addition of an info printk to ia64_mca_check_errors(), to match 2.4. Now we just get one line to say that a record has been detected, except for MCA which prints nothing at all.

I've been doing some performance tuning and adding some functionality to sba_iommu for zx1/sx1000 chipsets. This adds: * Long overdue consistent_dma_mask support * Long overdue ability to do large mappings in the iommu * Tightened spinlock usage for better performance/scalability * Added branch prediction hints for some of the performance paths * Added explicit data prefetching to some performance paths - perfmon shows roughly a 20% decrease in L3 misses in the bitmap search code * Increased delayed resource freeing depth and added a separate lock per ioc to avoid contention * Added code to free up queued pdir entries should we be unable to find space for new ones (not that I've ever seen the pdir anywhere close to full) * Finished cleaning out the hint support code, Grant is maintaining this separately for now * Added option to control bypass of sg mappings separately from single/coherent mappings Much like the swiotlb, sba_iommu allows devices capable of 64bit addressing to bypass the iommu and DMA directly to/from memory. Using a worst case scenario test (64bit bypass disabled, all DMA mapped through the iommu), I saw a 60% increase in sequential block input throughput using bonnie++ on a large RAID0 MD array. In fact, this patch provides the best bonnie++ performance with bypass disabled. This is likely due to benefits seen from coalescing the scatterlist, allowing better disk streaming. I assume that network performance will likely be limited by mapping latency, so I added the last bullet item to allow sg mappings to get the benefit of coalescing while keeping a low latency path for single and coherent mappings. If anyone is setup for network benchmarks, I'd be interested in a before and after with this patch.

This patch fixes a corner-case of ld.a emulation. ld.a should be emulated such that it always loads a misaligned value and clears the corresponding ALAT entry. The old emulation was correct for the case where ld.a was followed by ld.c/chk.a (since ALAT entry was cleared), but wrong for the case where it _wasn't_ followed by ld.c/chk.a. In that case, the misaligned value wasn't read from memory, as it should have been.

With 32 bit sector_t the block device size _in bytes_ is also cut to 32 bit in __set_size when the block device is mount (a filesystem mounted). The argument should be cast to loff_t before expanding the sector count to a byte count and calling i_size_write. [Christophe Saout]

From John McKell <mckellj@iomega.com>: This patch for scsi/sr.c and cdrom/cdrom.c persuades /proc/sys/dev/cdrom/info to report that connecting a drive via USB rather than ATAPI in fact does not make it able to write DVD-R. Without this patch, when sr0 and hdd are the same type of device connected via USB and ATAPI respectively, I see: $ cat /proc/sys/dev/cdrom/info: drive name: sr1 sr0 hdd ... Can write CD-R: 1 0 0 Can write CD-RW: 1 0 0 Can read DVD: 0 0 0 Can write DVD-R: 1 1 0 Can write DVD-RAM: 0 0 0 Can read MRW: 0 0 0 Can write MRW: 0 0 0 With this patch applied, instead I see: $ cat /proc/sys/dev/cdrom/info: drive name: sr1 sr0 hdd ... Can write CD-R: 1 0 0 Can write CD-RW: 1 0 0 Can read DVD: 0 0 0 Can write DVD-R: 0 0 0 Can write DVD-RAM: 0 0 0 Can read MRW: 0 0 0 Can write MRW: 0 0 0 The sr1 device in particular is an ordinary CD-RW that in fact cannot write DVD-R. While messing with this code, I also thought to tweak the /proc formatting to align the tabbed columns.

Here's a new version of the patch according to our discussion. This allows the platform to add its own platform files to the sysfs PCI device node through a "pcibios_add_platform_entries()" call. I added an empty pcibios_add_platform_entries() inline to all archs that apparently have PCI and implemented the OF stuff for ppc and ppc64. The name is still "devspec" for now, I doubt it will conflict and that's consistent with our use of the "devspec" name in other places.

From: Nathan Scott <nathans@sgi.com>, Andreas Gruenbacher <agruen@suse.de> XFS regression tests tripped a couple of problems with the recent xattr fix. When a size of 0 is passed in, the getxattr and listxattr syscalls return the size that would be required for the value or list of names, without actually returning the value. The previous patch accidentally removed this test, and so querying the required size broke.
