staging: android/lowmemorykiller: Better mm handling

LMK should not directly check for task->mm. The reason is that the
process' threads may exit or detach its mm via use_mm(), but other
threads may still have a valid mm. To catch this we use
find_lock_task_mm(), which walks up all threads and returns an
appropriate task (with lock held).

staging: android/lowmemorykiller: Don't grab tasklist_lock

Grabbing tasklist_lock has its disadvantages, i.e. it blocks
process creation and destruction. If there are lots of processes,
blocking doesn't sound as a great idea.

For LMK, it is sufficient to surround tasks list traverse with
rcu_read_{,un}lock().

>From now on using force_sig() is not safe, as it can race with an

v2 of this patch is, IMHO, easier to read than v1. Compared to
that patch it uses __u8 instead of unsigned char, for

uml: fix compile for x86-64

Randy Dunlap reports that we get

  arch/x86/um/shared/sysdep/ptrace.h:7:20: error: redefinition of 'regs_return_value'
  arch/x86/um/shared/sysdep/ptrace.h:7:20: note: previous definition of 'regs_return_value' was here

when compiling UML for x86-64.

Stephen Rothwell root-caused it and says:

 "Caused by commit d7e7528bcd45 ("Audit: push audit success and retcode
  into arch ptrace.h") (another patch that was never in linux-next :-().

  This file now needs protection against double inclusion."

so let's do as the man says.

tpm: fix (ACPI S3) suspend regression

This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e6713fcb ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.

The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver...  Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.
