2010-08-03amd64_edac: Remove polling mechanismBorislav Petkov
Switch to reusing the mcheck core's machine check polling mechanism instead of duplicating functionality by using the EDAC polling routine. Correct formatting while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Acked-by: Doug Thompson <dougthompson@xmission.com>
2010-08-03amd64_edac: Remove unneeded definesBorislav Petkov
All F2x110-related bit defines are used at only one place so replace them with simple BIT() macros. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Acked-by: Doug Thompson <dougthompson@xmission.com>
2010-08-03edac: Remove EDAC_DEBUG_VERBOSEBorislav Petkov
This option differs from EDAC_DEBUG only by printing the file and line of where the debug statement is placed, which contains unneeded information. So remove it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Acked-by: Doug Thompson <dougthompson@xmission.com>
2010-08-03amd64_edac: Sanitize syndrome extractionBorislav Petkov
Remove the two syndrome extraction macros and add a single function which does the same thing but with proper typechecking. While at it, make sure to cache ECC syndrome size and dump it in debug output. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

2010-08-03ACPI: Provide /sys/kernel/debug/ec/...Thomas Renninger
This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.

The callers of wmi_query_block() pass ACPI_ALLOCATE_BUFFER, and thus must check its return value before accessing or kfree() on the buffer.

2010-08-03toshiba_acpi: make remove_device() and add_device() voidAxel Lin
remove_device() and add_device() are not related to ACPI APIs, it does not make sense to return acpi_status for both functions. Current implementation of add_device() always AE_OK, thus the return value checking for add_device() always return false for ACPI_FAILURE(status). This patch makes add_device() to be void and remove the unnecessary return value checking. remove_proc_entry() won't fail, thus change remove_device() to be void.

2010-08-03acerhdf: fix resource reclaim in error pathAxel Lin
Fix resource reclaim in below cases: 1. acerhdf_register_platform() does not properly handle platform_device_alloc() failure and platform_device_add() failure This patch adds error handing for acerhdf_register_platform(). 2. acerhdf_register_platform() return err with acerhdf_dev == NULL. as a result, acerhdf_unregister_platform() does not do resource reclaim in acerhdf_init() error path. This patch adds error handing for acerhdf_register_platform(), thus correct the error handing path in acerhdf_init(). goto out_err instead of err_unreg if acerhdf_register_platform() fail. 3. platform_device_del() should only used in error handling. Current implementation missed a platform_device_put() in acerhdf_exit. This patch fixes it by using platform_device_unregister() instead of platform_device_del() in acerhdf_unregister_platform.
