Linus Torvalds 7f268a2ba7 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (30 commits)
  Blackfin arch: If we double fault, rather than hang forever, reset
  Blackfin arch: When icache is off, make sure people know it
  Blackfin arch: Fix bug - skip single step in high priority interrupt handler instead of disabling all interrupts in single step debugging.
  Blackfin arch: cache the values of vco/sclk/cclk as the overhead of doing so (~24 bytes) is worth avoiding the software mult/div routines
  Blackfin arch: fix bug - IMDMA is not type struct dma_register
  Blackfin arch: check the EXTBANKS field of the DDRCTL1 register to see if we are using both memory banks
  Blackfin arch: Apply Bluetechnix CM-BF527 board support patch
  Blackfin arch: Add unwinding for stack info, and a little more detail on trace buffer
  Blackfin arch: Add ISP1760 board resources to BF548-EZKIT
  Blackfin arch: fix bug - detect 0.1 silicon revision BF527-EZKIT as 0.0 version
  Blackfin arch: add missing IORESOURCE_MEM flags to UART3
  Blackfin arch: Add return value check in bfin_sir_probe(), remove SSYNC().
  Blackfin arch:  Extend sram malloc to handle L2 SRAM.
  Blackfin arch: Remove useless config option.
  Blackfin arch:  change L1 malloc to base on slab cache and lists.
  Blackfin arch: use local labels and ENDPROC() markings
  Blackfin arch: Do not need this dualcore test module in kernel.
  Blackfin arch: Allow ptrace to peek and poke application data in L1 data SRAM.
  Blackfin arch: Add ANOMALY_05000368 workaround
  Blackfin arch: Functional power management support

Michael Hennerich 68e2fc78e5 Blackfin arch: Fix bug - Kernel does not boot if re-program clocks
Don't write conflicting data to EBIU_SDBCTL after the SDRAM is
configured. This can cause data corruption, since we might change SDRAM
row and column addressing modes.
