Since all boards specify base_baud, the code to default base_baud to the architecture-defined BASE_BAUD is redundant. Also, defaulting to the architecture-defined BASE_BAUD is wrong since the UARTs on a serial PCI card will be clocked at the same rate no matter what the architecture of the host machine.

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> This skips the GP-loading function prologue (two instructions: 8 bytes) on BRSGP linkage correctly, fixing an oops on alpha while loading the aic7xxx driver.

mapped memory. A regular "memset()" may be using cache control instructions etc, which is not appropriate for memory-mapped IO. This also fixes a warning.

Patch from Robin Farine Fix the xscale cache handling routines that were invalidating a D cache line instead of draining the write & fill buffer as intended.

Patch from Catalin Marinas Unlike the v5 architecture, the ARM1136 requires that BIT4 is 0 in the first level page descriptor (ARM1136 TRM, page 6-39). It works at the moment but it might break future v6 cores.

Patch from Catalin Marinas The v6_dma_invalidate_range - the "mcr" instruction for draining the write buffer requires r0 == 0. A "cmp" instruction for testing the end address is missing in the v6_dma_flush_range function.

Patch from Catalin Marinas The _raw_write_(try)lock functions in include/asm-arm/spinlock.h should use the early clobber modifier (&) for the "tmp" register. A newer compiler (gcc-3.4.0) generates an "strexeq %0, %1, [%2]" instruction where %0 is the same as %2, which is illegal.

Patch from Catalin Marinas In the blockops_check() function, cache_type is uninitialised because an "mcr" instruction is used instead of "mrc".

This fixes the problem with recursion into filesystem when inode of quota file needs a page + some other allocation problems. I hope I got the GFP mask setting right..

Remove unused 'done_late' arg to ata_qc_complete(), which was never useful in 2.4, and never used at all in 2.6. This allows us to eliminate the same arg from ata_dma_complete(), and also make it more correct by passing the command rather than the ATA port structure as arg0.

We need to always allocate at least one indirect block pointer, since we always fill out blocks[0] even if we don't have any groups.

Trivia. CMD640 driver doesn't use generic IDE PCI code (it doesn't even include this header).

- many Maxtor disks incorrectly claim CACHE FLUSH EXT command support, fix it by checking both CACHE FLUSH EXT command and LBA48 support (thanks to Eric D. Mudama for help in fixing this) - write_cache() was called with 'drive->id->cfs_enable_2 & 0x3000' as 'int arg' argument which was always truncated to zero due to 'u8 drive->wcache = arg' assignment so write cache was indeed enabled but drive->wcache was zero (thanks to Rene Herman for help in debugging this) - flush cache in idedisk_start_power_step() only if ATA-6 CACHE FLUSH (EXT) bits are present in disk's identify data (prevents sending unknown commands) - set drive->wcache in idedisk_setup() not idedisk_attach() (no need to check id->command_set_2 - we check id->cfs_enable_2 instead in write_cache() call) - use ide_cacheflush_p() in idedisk_setup() - minor cleanups

This code is shared between i386 and x86-64, and x86-64 needs to check for empty nodes here. Otherwise you can get oopses at boot in some circumstances. This handles empty nodes != 0; empty node zero are still broken in other ways.

This changes the /dev/mem caching behaviour on x86-64 to be compatible with i386. By default everything is set cached. This actually makes WC MTRRs on AMD systems work, which would get overriden by the UC PAT bits that were set earlier. This can make DVD decoding with hardware support a lot faster. It also supports O_SYNC now, like i386, although that is not really safe, because it allows the user to create undefined cache attribute conflicts that can corrupt caches in some circumstances. I kept it for now. Better would to disallow it, until Terrence Ripperda's PAT framework is getting merged, that can avoid these problems. Actually it would be probably a good idea to add a printk here to catch broken programs for i386 and x86-64, but that is for another patch.

Various accumulated x86-64 patches and bug fixes. It fixes one nasty bug that has been there since NX is used by default in the kernel. With heavy AGP memory allocation it would set NX on parts of the kernel mapping in some corner cases, which gave endless crash loops. Thanks goes to some wizards in AMD debug labs for getting a trace out of this. Also various other fixes. This patches only changes x86-64 specific files, i have some changes outside too that I am sending separately. - Fix help test for CONFIG_NUMA - Don't enable SMT nice on CMP - Move HT and MWAIT checks up to generic code - Update defconfig - Remove duplicated includes (Arthur Othieno) - Set up GSI entry for ACPI SCI correctly (from i386) - Fix some comments - Fix threadinfo printing in oopses - Set task alignment to 16 bytes - Handle NX bit for code pages correctly in change_page_attr() - Use generic nops for non amd specific kernel - Add __KERNEL__ checks in unistd.h (David Lee)

From: Olaf Kirch <okir@suse.de> Authentication code in net/sunrpc makes frequent use of groups_alloc(0), which seems to clobber memory past the end of what it allocated. If called with gidsetsize == 0, groups_alloc will set nblocks = 0, but still does a group_info->blocks[0] = group_info->small_block;

From: Bart Samwel <bart@samwel.tk> The attached patch is the outcome of a discussion with Nathan. When laptop mode is active, there is no need for XFS to wake up xfsbufd (the daemon that flushes buffers that are too old) too often. The default is once every second, this patch makes laptop mode do it once every 30 seconds.

From: Christoph Hellwig <hch@lst.de> Someone blindly added sysfs support to the driver long time ago without understanding the implications (and if they were understood the driver would need half a rewrite for it). Herber Xu recently noticed the problems this causes on unload, so let's if 0 out all that code and get the driver working again.

It's silly that writing to /proc/sysrq-trigger does nothing if you haven't enabled /proc/sys/kernel/sysrq. So provide a new __handle_sysrq() which ignores the sysrq_enabled check. The patch also withdraws __handle_sysrq_nolock() from the kernel API. It had no callers.
