Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git acpica This will update the files shown below. Nothing Earth-shaking in this ACPICA update. The most "interesting", perhaps, is a workaround we had to put in place for some Toshiba machines which corrupt their DSDT at run-time. thanks, Len Brown Intel Open Source Technology Center ps. individual patches are available on linux-acpi@xxxxxxxxxxxxxxx and a consolidated plain patch is available here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/2.6.34/acpi-acpica-20100428-2.6.34-rc5.diff.gz Documentation/kernel-parameters.txt | 1 + arch/x86/kernel/acpi/boot.c | 4 + drivers/acpi/acpica/Makefile | 4 +- drivers/acpi/acpica/acevents.h | 51 ++- drivers/acpi/acpica/acglobal.h | 25 +- drivers/acpi/acpica/acinterp.h | 9 +- drivers/acpi/acpica/aclocal.h | 19 +- drivers/acpi/acpica/actables.h | 4 + drivers/acpi/acpica/dsfield.c | 2 +- drivers/acpi/acpica/dsmethod.c | 2 +- drivers/acpi/acpica/dsmthdat.c | 10 +- drivers/acpi/acpica/dsobject.c | 14 +- drivers/acpi/acpica/dsopcode.c | 13 +- drivers/acpi/acpica/dswexec.c | 6 +- drivers/acpi/acpica/dswstate.c | 10 +- drivers/acpi/acpica/evevent.c | 2 +- drivers/acpi/acpica/evgpe.c | 167 ++++++--- drivers/acpi/acpica/evgpeblk.c | 766 +++-------------------------------- drivers/acpi/acpica/evgpeinit.c | 653 +++++++++++++++++++++++++++++ drivers/acpi/acpica/evgpeutil.c | 337 +++++++++++++++ drivers/acpi/acpica/evmisc.c | 2 +- drivers/acpi/acpica/evxface.c | 24 +- drivers/acpi/acpica/evxfevnt.c | 191 +++++---- drivers/acpi/acpica/exconfig.c | 21 +- drivers/acpi/acpica/exconvrt.c | 4 +- drivers/acpi/acpica/excreate.c | 4 +- drivers/acpi/acpica/exdebug.c | 261 ++++++++++++ drivers/acpi/acpica/exfield.c | 2 +- drivers/acpi/acpica/exfldio.c | 16 +- drivers/acpi/acpica/exmisc.c | 8 +- drivers/acpi/acpica/exmutex.c | 46 +- drivers/acpi/acpica/exnames.c | 4 +- drivers/acpi/acpica/exoparg1.c | 18 +- drivers/acpi/acpica/exoparg2.c | 37 +-- drivers/acpi/acpica/exoparg3.c | 4 +- drivers/acpi/acpica/exoparg6.c | 4 +- drivers/acpi/acpica/exprep.c | 4 +- drivers/acpi/acpica/exregion.c | 17 +- drivers/acpi/acpica/exresnte.c | 4 +- drivers/acpi/acpica/exresolv.c | 11 +- drivers/acpi/acpica/exresop.c | 8 +- drivers/acpi/acpica/exstore.c | 218 +---------- drivers/acpi/acpica/exsystem.c | 10 +- drivers/acpi/acpica/hwregs.c | 6 +- drivers/acpi/acpica/hwsleep.c | 2 +- drivers/acpi/acpica/hwvalid.c | 2 +- drivers/acpi/acpica/nsaccess.c | 2 +- drivers/acpi/acpica/nsdump.c | 4 +- drivers/acpi/acpica/nsnames.c | 2 +- drivers/acpi/acpica/nssearch.c | 2 +- drivers/acpi/acpica/nsutils.c | 4 +- drivers/acpi/acpica/psargs.c | 4 +- drivers/acpi/acpica/psloop.c | 3 +- drivers/acpi/acpica/psxface.c | 5 + drivers/acpi/acpica/rscreate.c | 14 +- drivers/acpi/acpica/rslist.c | 6 +- drivers/acpi/acpica/rsmisc.c | 4 +- drivers/acpi/acpica/tbfadt.c | 16 +- drivers/acpi/acpica/tbfind.c | 2 +- drivers/acpi/acpica/tbinstal.c | 69 ++-- drivers/acpi/acpica/tbutils.c | 101 ++++- drivers/acpi/acpica/tbxface.c | 80 +++- drivers/acpi/acpica/tbxfroot.c | 6 +- drivers/acpi/acpica/utalloc.c | 2 +- drivers/acpi/acpica/utcopy.c | 14 +- drivers/acpi/acpica/utdelete.c | 6 +- drivers/acpi/acpica/uteval.c | 2 +- drivers/acpi/acpica/utglobal.c | 1 + drivers/acpi/acpica/utmisc.c | 6 +- drivers/acpi/acpica/utmutex.c | 4 +- drivers/acpi/acpica/utobject.c | 8 +- drivers/acpi/bus.c | 44 ++ drivers/acpi/scan.c | 2 +- drivers/acpi/system.c | 5 +- include/acpi/acexcep.h | 2 +- include/acpi/acoutput.h | 2 + include/acpi/acpiosxf.h | 4 +- include/acpi/acpixf.h | 43 +- include/acpi/actbl2.h | 27 ++ include/acpi/actypes.h | 44 +- 80 files changed, 2143 insertions(+), 1424 deletions(-) create mode 100644 drivers/acpi/acpica/evgpeinit.c create mode 100644 drivers/acpi/acpica/evgpeutil.c create mode 100644 drivers/acpi/acpica/exdebug.c through these commits: Alexey Starikovskiy (1): ACPICA: Fix for acpi_reallocate_root_table for incorrect root table copy Bob Moore (12): ACPICA: Add support for MCHI table ACPICA: Standardize integer output for ACPICA warnings/errors ACPICA: Update version to 20100304 ACPICA: Update comments/headers, no functional change ACPICA: Add write support for DataTable operation regions ACPICA: Update DSDT copy/detection.

This is caused by commit aa2110c (ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT). DMI is not initialized yet in acpi_early_init on ia64. The DSDT DMI check table is x86 specific, so make it empty on other archs. And this fixes the warnings on ia64.

But the port and Rafael's original patch have some differences, so we made below patch to make linux GPE code consistent with ACPICA code base. Most changes are about comments and coding styles. Other noticeable changes are based on: Rafael: Reduce code duplication related to GPE lookup https://patchwork.kernel.org/patch/86237/ Rafael: Always use the same lock for GPE locking https://patchwork.kernel.org/patch/90471/ A new field gpe_count in struct acpi_gpe_block_info to record the number of individual GPEs in block.
