ARC: Fix KSTK_ESP()

2015-03-18T13:11:03+00:00

commit 13648b0118a24f4fc76c34e6c7b6ccf447e46a2a upstream.

/proc//maps currently don't annotate stack vma with "[stack]"
This is because KSTK_ESP ie expected to return usermode SP of tsk while
currently it returns the kernel mode SP of a sleeping tsk.

While the fix is trivial, we also need to adjust the ARC kernel stack
unwinder to not use KSTK_SP and friends any more.

Merge tag 'remove-weak-declarations' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

2014-10-23T22:04:27+00:00

Pull weak function declaration removal from Bjorn Helgaas:
 "The "weak" attribute is commonly used for the default version of a
  function, where an architecture can override it by providing a strong
  version.

  Some header file declarations included the "weak" attribute.  That's
  error-prone because it causes every implementation to be weak, with no
  strong version at all, and the linker chooses one based on link order.

  What we want is the "weak" attribute only on the *definition* of the
  default implementation.  These changes remove "weak" from the
  declarations, leaving it on the default definitions"

* tag 'remove-weak-declarations' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
  uprobes: Remove "weak" from function declarations
  memory-hotplug: Remove "weak" from memory_block_size_bytes() declaration
  kgdb: Remove "weak" from kgdb_arch_pc() declaration
  ARC: kgdb: generic kgdb_arch_pc() suffices
  vmcore: Remove "weak" from function declarations
  clocksource: Remove "weak" from clocksource_default_clock() declaration
  x86, intel-mid: Remove "weak" from function declarations
  audit: Remove "weak" from audit_classify_compat_syscall() declaration

ARC: kgdb: generic kgdb_arch_pc() suffices

2014-10-22T22:14:04+00:00

The ARC version of kgdb_arch_pc() is identical to the generic version in
kernel/debug/debug_core.c.  Drop the ARC version so we use the generic one.

* No active users of this flag anymore

* flag itself was no longer usable with new simualtor which acts just like
  hardware, not providing the special chip-id = 0xffff which good old

ARC: Allow SMP kernel to build/boot on UP-only infrastructure

2014-09-27T09:19:01+00:00

In light of recent SNAFU with SMP build, allow simple platform to build
as SMP but run UP.

* Remove the dependence on simulation SMP extension to enable quick
  build/test iterations of SMP kernel.

* In absence of platform SMP registration, prevent the NULL smp feature
  name from borkign the system
