      ARM: mxc: Add missing lockdep annotation · b5eee2fd
      由 Thomas Gleixner 提交于 
      The irq_set_wake() function of the gpio irq_chip calls
enable/disable_irq_wake() on the demultiplex interrupt. That leads to
a lockdep warning "INFO: possible recursive locking detected" because
irq_set_type() is called under irq_desc->lock and the *_irq_wake()
calls take irq_desc->lock of the demux interrupt.

Tell lockdep that the gpio irqs are in a different lock class.

Documentation/SubmitChecklist:
 15: All codepaths have been exercised with all lockdep features enabled.

That's a non-optional requirement, AFAICT.

      ARM: mxc: Correct data alignment in headsmp.S for CONFIG_THUMB2_KERNEL · 0575b4b8
      由 Dave Martin 提交于 
      Directives such as .long and .word do not magically cause the
assembler location counter to become aligned in gas.  As a
result, using these directives in code sections can result in
misaligned data words when building a Thumb-2 kernel
(CONFIG_THUMB2_KERNEL).

This is a Bad Thing, since the ABI permits the compiler to
assume that fundamental types of word size or above are word-
aligned when accessing them from C.  If the data is not really
word-aligned, this can cause impaired performance and stray
alignment faults in some circumstances.

In general, the following rules should be applied when using
data word declaration directives inside code sections:

    * .quad and .double:
         .align 3

    * .long, .word, .single, .float:
         .align (or .align 2)

    * .short:
        No explicit alignment required, since Thumb-2
        instructions are always 2 or 4 bytes in size.
        immediately after an instruction.
