      [PATCH] ARM: 2753/1: move ixdp* cpld mappings · 91f6a589
      Lennert Buytenhek authored
      Patch from Lennert Buytenhek
      
      All ixdp platforms currently have a cpld mapped in at 0xfafff000.
      Since this address is not 1M-aligned, a regular page mapping will be
      used instead of a section mapping, which opens up the possibility of
      triggering ixp2400 erratum #66 as we only do the XCB=101 workaround
      thing for section mappings.
      There is still a lot of space higher up in the virtual memory map
      for 1M mappings, so move the cpld mapping to 0xfe000000 and make it
      1M big so that a section mapping will be used for it.

      [PATCH] ARM: Add SA_TIMER flag to timer interrupts · 09b8b5f8
      Russell King authored
      VST needs to know which timer handler is for the timer interrupt.
      Mark all timer interrupts with the SA_TIMER flag.

      [PATCH] Cleanup patch for process freezing · 3e1d1d28
      Christoph Lameter authored
      1. Establish a simple API for process freezing defined in linux/include/sched.h:
      
         frozen(process)		Check for frozen process
         freezing(process)		Check if a process is being frozen
         freeze(process)		Tell a process to freeze (go to refrigerator)
         thaw_process(process)	Restart process
         frozen_process(process)	Process is frozen now
      
      2. Remove all references to PF_FREEZE and PF_FROZEN from all
         kernel sources except sched.h
      
      3. Fix numerous locations where try_to_freeze is manually done by a driver
      
      4. Remove the argument that is no longer necessary from two function calls.
      
      5. Some whitespace cleanup
      
      6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
         cleared before setting PF_FROZEN, recalc_sigpending does not check
         PF_FROZEN).
      
      This patch does not address the problem of freeze_processes() violating the rule
      that a task may only modify its own flags by setting PF_FREEZE. This is not clean
      in an SMP environment. freeze(process) is therefore not SMP safe!
