Hans de Goede 62ba6d817c ACPICA: Fix race in generic_serial_bus (I2C) and GPIO op_region parameter handling 
commit c27f3d011b08540e68233cf56274fdc34bebb9b5 upstream.

ACPICA commit c9e0116952363b0fa815143dca7e9a2eb4fefa61

The handling of the generic_serial_bus (I2C) and GPIO op_regions in
acpi_ev_address_space_dispatch() passes a number of extra parameters
to the address-space handler through the address-space Context pointer
(instead of using more function parameters).

The Context is shared between threads, so if multiple threads try to
call the handler for the same address-space at the same time, then
a second thread could change the parameters of a first thread while
the handler is running for the first thread.

An example of this race hitting is the Lenovo Yoga Tablet2 1015L,
where there are both attrib_bytes accesses and attrib_byte accesses
to the same address-space. The attrib_bytes access stores the number
of bytes to transfer in Context->access_length. Where as for the
attrib_byte access the number of bytes to transfer is always 1 and
field_obj->Field.access_length is unused (so 0). Both types of
accesses racing from different threads leads to the following problem:

 1. Thread a. starts an attrib_bytes access, stores a non 0 value
    from field_obj->Field.access_length in Context->access_length

 2. Thread b. starts an attrib_byte access, stores 0 in
    Context->access_length

 3. Thread a. calls i2c_acpi_space_handler() (under Linux). Which
    sees that the access-type is ACPI_GSB_ACCESS_ATTRIB_MULTIBYTE
    and calls acpi_gsb_i2c_read_bytes(..., Context->access_length)

 4. At this point Context->access_length is 0 (set by thread b.)

rather then the field_obj->Field.access_length value from thread a.
This 0 length reads leads to the following errors being logged:

 i2c i2c-0: adapter quirk: no zero length (addr 0x0078, size 0, read)
 i2c i2c-0: i2c read 0 bytes from client@0x78 starting at reg 0x0 failed, error: -95

Note this is just an example of the problems which this race can cause.

There are likely many more (sporadic) problems caused by this race.

This commit adds a new context_mutex to struct acpi_object_addr_handler
and makes acpi_ev_address_space_dispatch() take that mutex when
using the shared Context to pass extra parameters to an address-space
handler, fixing this race.

Note the new mutex must be taken *after* exiting the interpreter,
therefor the existing acpi_ex_exit_interpreter() call is moved to above
the code which stores the extra parameters in the Context.
