This patch makes the b44-after-bcm4400 scenario work for me. What was happening is that the broadcom driver sets a "power off MAC" bit, and we didn't remove that when initializing the chip. Also added some (a bit ugly, I know ) logic to clear up the address filter stuff, which is what recent broadcom drivers do...

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: Paul Mundt <lethal@linux-sh.org> The old drivers/char sh-sci driver is no long used by anyone, both sh and h8300 are using the drivers/serial version at this point, so we can get rid of the old one entirely.

From: Andi Kleen <ak@muc.de> *** Warning: "memcmp" [drivers/atm/zatm.ko] undefined! gcc 3.4 specific problem. This patch should fix it. Actually it would be better to move all these EXPORT_SYMBOLs into lib/string.c, it is silly that each arch has to duplicate all that.

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.

From: Mathieu Chouquet-Stringer <mchouque@online.fr> This patch makes the following code work again: #ifdef STT_REGISTER if (info->hdr->e_machine == EM_SPARC || info->hdr->e_machine == EM_SPARCV9) { /* Ignore register directives. */ if (ELF_ST_TYPE(sym->st_info) == STT_REGISTER) break; } #endif This portion of code is sparc specific and nothing else in modpost.c uses e_machine meaning cross-compiling for sparc on i386 (or any little endian machine) is the only way to experience the bug. Without it, e_machine has the wrong value and modpost then generates a lot of "*** Warning: \"symbol\" [filename.ko] undefined" messages.

From: Arjan van de Ven <arjanv@redhat.com>, Rusty Russell <rusty@rustcorp.com.au> The patch below resolves the "Not Yet Implemented" print_modules() thing. This is a really useful feature for distros; it allows us to do statistical analysis on which modules are present how often in oopses compared to how often they are used normally. In addition it helps to spot candidates for certain bugs without having to go back to the customer asking for this information.

From: Alan Cox <alan@redhat.com> The block layer checks for -EINVAL from block layer driver ioctls. This is wrong - ENOTTY is unknown and some drivers correctly use this. I suspect for an internal ioctl 2.7 should change to -ENOIOCTLCMD and bitch about old style returns This is conservative fix for the 2.6 case, it keeps the bogus -EINVAL to avoid breaking stuff

From: Greg Edwards <edwardsg@sgi.com> On ia64, EXEC_PAGESIZE (max page size) is 65536, but the default page size is 16k. This results in NGROUPS_PER_BLOCK in include/linux/sched.h being calculated incorrectly when the page size is anything other than 64k. For example, on a 16k page size kernel, a setgroups() call with a gidsetsize of 65536 will end up walking over memory since only 1/4 of the needed pages were allocated for the blocks[] array in the group_info struct. Patch below calculates NGROUPS_PER_BLOCK from PAGE_SIZE instead.
