* '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

Remove arch-specific show_mem() in favor of the generic version.
This also removes the following redundant information display:
- free pages, printed by show_free_areas()
- pages in swapcache, printed by show_swap_cache_info()where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().Signed-off-by: Johannes Weiner

Jack Ren and Eric Miao tracked down the following long standing
problem in the NOHZ code:scheduler switch to idle task
enable interruptsWindow starts here
----> interrupt happens (does not set NEED_RESCHED)
irq_exit() stops the tick----> interrupt happens (does set NEED_RESCHED)
return from schedule()
cpu_idle(): preempt_disable();
Window ends here
The interrupts can happen at any point inside the race window. The
first interrupt stops the tick, the second one causes the scheduler to
rerun and switch away from idle again and we end up with the tick
disabled.The fact that it needs two interrupts where the first one does not set
NEED_RESCHED and the second one does made the bug obscure and extremly
hard to reproduce and analyse. Kudos to Jack and Eric.Solution: Limit the NOHZ functionality to the idle loop to make sure
that we can not run into such a situation ever again.cpu_idle()
{
preempt_disable();while(1) {
tick_nohz_stop_sched_tick(1); ,

The dm9000 driver accepts either 2 or 3 resources to describe the platform
devices. The 2 resources case abuses the ioresource mechanism by passing
ioremap()ed memory through the platform device resources. This patch removes
converts boards that were using it to the 3 resources scheme.CC: Bryan Wu
