Predicate can be used for an implicit return value. This change improves the implicit return mechanism to be more compatible with the MS interpreter. http://www.acpica.org/bugzilla/show_bug.cgi?id=349 Below AML code from http://bugzilla.kernel.org/show_bug.cgi?id=10686 Store(0x07D6, OSYS) Method (_CRT, 0, Serialized) { If (LLess (OSYS, 0x07D6)) { If (LEqual (\_SB.TJ85, Zero)) { Return (Add (0x0AAC, Multiply (TPC, 0x0A))) } Else { Return (Add (0x0AAC, Multiply (TP85, 0x0A))) } } } Previously _CRT returns 0x07D6, now it returns 0 (predicate value of LLess) Signed-off-by:

Fixed two possible memory leaks in the error exit paths of acpi_ut_update_objerct_reference() and acpi_ut_walk_package_tree() These functions are similar in that they use a stack of state objects in order to eliminate recursion. The stack must be fully deallocated if an error occurs. http://www.acpica.org/bugzilla/show_bug.cgi?id=383Signed-off-by:

Previously aborted with error if too few arguments were passed to a control method via the external ACPICA interface. Now issue a warning instead and continue. Handles the case where the method inadvertently declares too many arguments, but does not actually use the extra ones. Applies mainly to the predefined methods. http://bugzilla.kernel.org/show_bug.cgi?id=11032Signed-off-by:

Removed ACPI_DB_WARN and ACPI_DB_ERROR. These debug levels were made obsolete by the ACPI_WARNING and ACPI_ERROR/ACPI_EXCEPTION interfaces. Also added ACPI_DB_EVENTS to correspond with the existing ACPI_LV_EVENTS. Signed-off-by:

Lin Ming authored
ACPI_DB_ERROR and ACPI_DB_WARN were removed from ACPICA core. So replace ACPI_DEBUG_PRINT((ACPI_DB_ERROR, ...) with printk(KERN_ERR PREFIX ...) and ACPI_DEBUG_PRINT((ACPI_DB_WARN, ...) with printk(KERN_WARNING PREFIX ...) We do not use ACPI_ERROR/ACPI_WARNING since they're not exported, see ------------------------------------------------------------- commit 6468463a Author: Len Brown <len.brown@intel.com> Date: Mon Jun 26 23:41:38 2006 -0400 ACPI: un-export ACPI_ERROR() -- use printk(KERN_ERR...)

Examines the return object from a call to acpi_evaluate_object. Any Index or RefOf references are automatically dereferenced in an attempt to return something useful (these reference types cannot be converted into an external ACPI_OBJECT.)

The "minimal" descriptors such as EndTag are calculated as 12 bytes long, but the actual length in the internal descriptor is 16 because of the round-up to 8 on 64-bit build. http://www.acpica.org/bugzilla/show_bug.cgi?id=728Signed-off-by:

Without this change, a table cannot be loaded again once it has been loaded/unloaded one time. The current mechanism does not unregister a table upon an unload. During a load, if the same table is found, this no longer returns an exception. http://www.acpica.org/bugzilla/show_bug.cgi?id=722Signed-off-by:

Previously, dynamically loaded tables were simply mapped, but on some machines this memory is corrupted after suspend. Now copy the table to a local buffer. For OpRegion case, added checksum verify. Use the table length from the table header, not the region length. For Buffer case, use the table length also. http://bugzilla.kernel.org/show_bug.cgi?id=10734Signed-off-by:

This is debatable, but while we're debating it, let's disallow the combination of splice and an O_APPEND destination. It's not entirely clear what the semantics of O_APPEND should be, and POSIX apparently expects pwrite() to ignore O_APPEND, for example. So we could make up any semantics we want, including the old ones. But Miklos convinced me that we should at least give it some thought, and that accepting writes at arbitrary offsets is wrong at least for IS_APPEND() files (which always have O_APPEND set, even if the reverse isn't true: you can obviously have O_APPEND set on a regular file). So disallow O_APPEND entirely for now. I doubt anybody cares, and this way we have one less gray area to worry about. Reported-and-argued-for-by:

This fixes the previous fix, which was completely wrong on closer inspection. This version has been manually tested with a user-space test harness and generates sane values. A nearly identical patch has been boot-tested. The problem arose from changing how kmalloc/kfree handled alignment padding without updating ksize to match. This brings it in sync. Signed-off-by:
