* [PATCH] IDE CD end-of media error fixAlan Cox2006-06-253-28/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch from Alan that fixes a real ide-cd.c regression causing bogus "Media Check" failures for perfectly valid Fedora install ISOs, on certain CD-ROM drives. This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the end of media problem. It may not be sufficient for some controllers (promise notably) and it does not touch the locking so the error path locking is as horked as in mainstream. From: Ingo Molnar <mingo@elte.hu> I have ported the patch to 2.6.17-rc4 and tested it by provoking end-of-media IO errors with an unaligned ISO image. Unlike the vanilla kernel, the patched kernel interpreted the error condition correctly with 512 byte granularity: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 Buffer I/O error on device hdc, logical block 163261 Buffer I/O error on device hdc, logical block 163262 the unpatched kernel produces an incorrect error dump: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306088 Buffer I/O error on device hdc, logical block 163261 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306096 Buffer I/O error on device hdc, logical block 163262 I do not have the right type of CD-ROM drive to reproduce the end-of-media data corruption bug myself, but this same patch in RHEL solved it.

* [PATCH] Make printk work for really early debuggingMichael Ellerman2006-06-252-17/+34
| | | | | | | | | | | | | | | | | | | | | | | | | Currently printk is no use for early debugging because it refuses to actually print anything to the console unless cpu_online(smp_processor_id()) is true. The stated explanation is that console drivers may require per-cpu resources, or otherwise barf, because the system is not yet setup correctly. Fair enough. However some console drivers might be quite happy running early during boot, in fact we have one, and so it'd be nice if printk understood that. So I added a flag (which I would have called CON_BOOT, but that's taken) called CON_ANYTIME, which indicates that a console is happy to be called anytime, even if the cpu is not yet online. Tested on a Power 5 machine, with both a CON_ANYTIME driver and a bogus console driver that BUG()s if called while offline. No problems AFAICT. Built for i386 UP & SMP.

* [PATCH] idetape gcc 4.1 warning fixDaniel Walker2006-06-251-16/+33
| | | | | | | | | | | | | | | | | | | | | | | | In both the read and write cases it will return an error if copy_{from/to}_user faults. However, I let the driver try to read/write as much as it can just as it normally would , then finally it returns an error if there was one. This was the most straight forward way to handle the error , since there isn't a clear way to clean up the buffers on error . I moved retval in idetape_chrdev_write() down into the actual code blocks since it's really once used there, and it conflicted with my ret variable.

| | | | | | | | | | | | | | | | | | | | | | ufs super block contains some statistic about file systems, like amount of directories, free blocks, inodes and so on. UFS1 hold this information in one location and uses 32bit integers for such information, UFS2 hold statistic in another location and uses 64bit integers. There is transition variant, if UFS1 has type 44BSD and flags field in super block has some special value this mean that we work with statistic like UFS2 does. and this also means that nobody care about old(UFS1) statistic. So if start fsck against such file system, after usage linux ufs driver, it found error: at now only UFS1 like statistic is updated. This patch should fix this. Also it contains some minor cleanup: CodingSytle and remove unused variables.

| | | | | | | | | | | | | | | | | | | | | | | | | Super block of UFS usually has size >512, because of fragment size may be 512, this cause some problems. Currently, there are two methods to work with ufs super block: 1) split structure which describes ufs super blocks into structures with size <=512 2) use one structure which describes ufs super block, and hope that array of "buffer_head" which holds "super block", has such construction: bh[n]->b_data + bh[n]->b_size == bh[n + 1]->b_data The second variant may cause some problems in the future, and usage of two variants cause unnecessary code duplication.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First of all some necessary notes about UFS by it self: To avoid waste of disk space the tail of file consists not from blocks (which is ordinary big enough, 16K usually), it consists from fragments(which is ordinary 2K). When file is growing its tail occupy 1 fragment, 2 fragments... At some stage decision to allocate whole block is made and all fragments are moved to one block. How this situation was handled before: ufs_prepare_write ->block_prepare_write ->ufs_getfrag_block ->... ->ufs_new_fragments: bh = sb_bread bh->b_blocknr = result + i; mark_buffer_dirty (bh); This is wrong solution, because: - it didn't take into consideration that there is another cache: "inode page cache" - because of sb_getblk uses not b_blocknr, (it uses page->index) to find certain block, this breaks sb_getblk. How this situation is handled now: we go though all "page inode cache", if there are no such page in cache we load it into cache, and change b_blocknr.

* [PATCH] Define __raw_get_cpu_var and use itPaul Mackerras2006-06-2511-7/+19
| | | | | | | | | | | | | | | | | | | | | | | There are several instances of per_cpu(foo, raw_smp_processor_id()), which is semantically equivalent to __get_cpu_var(foo) but without the warning that smp_processor_id() can give if CONFIG_DEBUG_PREEMPT is enabled. For those architectures with optimized per-cpu implementations, namely ia64, powerpc, s390, sparc64 and x86_64, per_cpu() turns into more and slower code than __get_cpu_var(), so it would be preferable to use __get_cpu_var on those platforms. This defines a __raw_get_cpu_var(x) macro which turns into per_cpu(x, raw_smp_processor_id()) on architectures that use the generic per-cpu implementation, and turns into __get_cpu_var(x) on the architectures that have an optimized per-cpu implementation.

* [PATCH] ensure NULL deref can't possibly happen in is_exported()Jesper Juhl2006-06-251-1/+1
| | | | | | | | | | | | If CONFIG_KALLSYMS is defined and if it should happen that is_exported() is given a NULL 'mod' and lookup_symbol(name, __start___ksymtab, __stop___ksymtab) returns 0, then we'll end up dereferencing a NULL pointer.

* [PATCH] Rewritten backlight infrastructure for portable Apple computersMichael Hanselmann2006-06-2526-711/+1529
| | | | | | | | | | | | | | | | This patch contains a total rewrite of the backlight infrastructure for portable Apple computers. Backward compatibility is retained. A sysfs interface allows userland to control the brightness with more steps than before. Userland is allowed to upload a brightness curve for different monitors, similar to Mac OS X.
