87cdece169 ACPICA: DT compiler: prevent error if optional field at the end of table is not present
ACPICA commit a7f73af9003bf4e730db5a133300c01ba7992a01

The data table compiler throws under the following conditions:
 1.) there is a table with a last field that is optional
 2.) if the optional field is not present
 3.) the optional field is the last line of the data table

A change was made to dt_compile_table to return an AE_EOF under
these conditions.  This AE_EOF means that we are at the end of the
file.  The caller to dt_compile_table() is responsible for handling
this case. For DBG2 table, we will complete the compilation of this
subtable.  For other tables, this could be different.

6e875fa048 ACPICA: Debugger: fix slight indentation issue
ACPICA commit c75af007d35c0afe8791ac39b7749c7442f49912

The %*s format specifier prints a string with a width indicated by an integer.

In the case of acpi_os_printf() ("%*s", acpi_gbl_nesting_level, " "),
a single space is printed to the console when acpi_gbl_nesting_level
is 0 or 1. This change increments acpi_gbl_nesting_level so that there
is one space printed when acpi_gbl_nesting_level is 0 and two spaces
printed when acpi_gbl_nesting_level is 1.

b43eac6f33 ACPICA: iASL: change processing of external op namespace nodes for correctness
ACPICA commit aa866a9b4f24bbec9f158d10325b486d7d12d90f

The declaration External (ABCD.EFGH) creates two nodes in the namespace: ABCD
and EFGH where ABCD is marked as an implicit external node. ABCD is labeled as
implicit because there does not exist a specific External (ABCD) declaration.

Before this change, the declaration External (ABCD.EFGH) and
External (ABCD.EFGH.IJKL) creates the namespace nodes ABCD, EFGH, and IJKL
where ABCD and EFGH are labeled as implicit external nodes. This is incorrect.
The only implicit node should be ABCD because EFGH and IJKL are explicit nodes.
This change fixes the labeling procecess of external op namespace nodes so that
nodes are properly labeled as implicit external.

Due to this commit, the below ASL code results in a compilation error.

164a08cee1 ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detection
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9

This patch implements a new infinite loop detection mechanism to replace
the old one, it uses acpi_os_get_timer() to limit loop execution into a
determined time slice.
This is useful in case some hardware/firmware operations really require the
AML interpreter to wait while the old mechanism could expire too fast on
recent machines.

The new mechanism converts old acpi_gbl_max_loop_iterations to store the user
configurable value for the new mechanism in order to allow users to be
still able to configure this value for acpiexec via command line. This
patch also removes wrong initilization code of acpi_gbl_max_loop_iterations
accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the
default value is also properly tuned for acpiexec). Reported by M. Foronda,
fixed by Lv Zheng.

29ad1f88ab ACPICA: Avoid null pointer dereference on Op.
ACPICA commit 08a00639b0d6756e8ba1421419fc3728904651d9

The calls to acpi_os_acquire_object can result in a null being assigned
to Op (for example if a mutex acquire fails) which can lead to a
null pointer dereference on Op on the call to ASL_CV_TRANSFER_COMMENTS
(via function cv_transfer_comments). Move the block into the previous
block that checks for a null Op so that we never can call
cv_transfer_comments with a null Op.

Detected by: coverity_scan CID#1371660 ("Dereference after null check")

8f275615a6 ACPICA: Fix an off-by-one error in acpi_get_timer_duration().
ACPICA commit b4fd33f3c2af014aeec978d46392d286fd7f52b3

Delta calculation has an off-by-one error when there is a rollover.
For example, when start_ticks is 0x00FFFFFF and end_ticks is 0x00000000
(for 24-bit timer), delta_ticks should be 1 (one) but it was 0 (zero).

8bafae202c ARM: BUG if jumping to usermode address in kernel mode
Detect if we are returning to usermode via the normal kernel exit paths
but the saved PSR value indicates that we are in kernel mode.  This
could occur due to corrupted stack state, which has been observed with
"ftracetest".

This ensures that we catch the problem case before we get to user code.
