2007-02-05[S390] move crypto options and some cleanup.Jan Glauber
This patch moves the config options for the s390 crypto instructions to the standard "Hardware crypto devices" menu. In addition some cleanup has been done: use a flag for supported keylengths, add a warning about machien limitation, return ENOTSUPP in case the hardware has no support, remove superfluous printks and update email addresses.

2007-02-05[S390] cpcmd with vmalloc addresses.Christian Borntraeger
Change the bounce buffer logic of cpcmd. diag8 needs _real_ memory below 2GB. Therefore vmalloced data does not work. As the data might cross a page boundary, we cannot use virt_to_page either. The solution is to use virt_to_page only in the check for a bounce buffer. There was a redundant check for response==NULL. response < 2GB contains this check as well. I also removed the rlen==0 check, since rlen=0 and response!=NULL would be a caller bug and response==NULL is already checked.

2007-02-03[PATCH] kexec: Avoid migration of already disabled irqs (ia64)Magnus Damm
This patch fixes up ia64 kexec support for HP rx2620 hardware. It does this by skipping migration of already disabled irqs. This is most likely a problem on other ia64 platforms as well, but I've only been able to reproduce it on one machine so far. The full story is that handle_bad_irq() gets invoked before starting the new kernel without this patch. This seems to happen when fixup_irqs() calls generic_handle_irq() on already migrated (and disabled) irqs. So by avoiding migration of disabled irqs we stay away of handle_bad_irq(). The code has been tested on three different ia64 machines, all with good results. It is possible to trigger the same bug by offlining a processor using echo 0 > /sys/devices/system/cpu/cpuX/online.

2007-02-02ACPI_NUMA: fix HP IA64 simulator issue with extended memory domainAlexey Starikovskiy
ACPI 3.0 incorporated the SRAT spec, upping the table version to 2, and extending the size of the proximity domain from 1-byte to 4-bytes. This extension was into a reserved field that firmware should set to 0, but the HP simulator had non-zero values there resulting in unexpected huge numbers. So mask the domain down to 8-bits for now. A more general fix will be to check the table version supplied by firmware and get paranoid about reserved fields.

2007-02-02Revert "[PATCH] fix typo in geode_configre()@cyrix.c"Linus Torvalds
This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba. It's not wrong, but it's not right either, and everybody seems to agree that the right fix is probably to do the ccr3 write after the ccr4 one (and that we also should clean it up a bit). And after that we need to really validate that all the bits that we write to ccr4 actually do work. The old 2.6.19 code was insane, and basically didn't change ccr4 at all (even though it certainly looks like it was the *intent* to do so). So let's revert the change that may fix things, just because it's not what was actually ever tested when the code was written, even if it _was_ the intent. There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was started by the patch that now gets reverted, and that discussion may well contain the proper long-term fix.

2007-02-01[PATCH] __crc_... is intended to be absoluteAl Viro
i386 boot/compressed/relocs checks for absolute symbols and warns about unexpected ones. If you build with modversions, you get ~2500 warnings about __crc_<symbol>. These suckers are really absolute symbols - we do _not_ want to modify them on relocation. They are generated by genksyms - EXPORT_... generates a weak alias, then genksyms produces an ld script with __crc_<symbol> = <checksum> and it's fed to ld to produce the final object file. Their only use is to match kernel and module at modprobe time; they _must_ be absolute. boot/compressed/relocs has a whitelist of known absolute symbols, but it doesn't know about __crc_... stuff. As the result, we get shitloads of false positives on any ld(1) version. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-01-30[PATCH] i386: In assign_irq_vector look at all vectors before giving upEric W. Biederman
When the world was a simple and static place setting up irqs was easy. It sufficed to allocate a linux irq number and a find a free cpu vector we could receive that linux irq on. In those days it was a safe assumption that any allocated vector was actually in use so after one global pass through all of the vectors we would have none left. These days things are much more dynamic with interrupt controllers (in the form of MSI or MSI-X) appearing on plug in cards and linux irqs appearing and disappearing. As these irqs come and go vectors are allocated and freed, invalidating the ancient assumption that all allocated vectors stayed in use forever. So this patch modifies the vector allocator to walk through every possible vector before giving up, and to check to see if a vector is in use before assigning it. With these changes we stop leaking freed vectors and it becomes possible to allocate and free irq vectors all day long. This changed was modeled after the vector allocator on x86_64 where this limitation has already been removed. In essence we don't update the static variables that hold the position of the last vector we allocated until have successfully allocated another vector. This allows us to detect if we have completed one complete scan through all of the possible vectors. Acked-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Eric W.
