The kernel debug_core invokes hw breakpoint install and removal via call backs. The architecture specific kgdb stubs only need to implement the call backs and not actually call the functions.

HW breakpoints events stopped working correctly with kgdb as a result of commit: 018cbffe (Merge commit 'v2.6.33' into perf/core), later commit: ba773f7c (x86,kgdb: Fix hw breakpoint regression) allowed breakpoints to propagate to the debugger core but did not completely address the original regression in functionality found in 2.6.35. When the DR_STEP flag is set in dr6 along with any of the DR_TRAP bits, the kgdb exception handler will enter once from the hw_breakpoint API call back and again from the die notifier for do_debug(), which causes the debugger to stop twice and also for the kgdb regression tests to fail running under kvm with: echo V2I1 > /sys/module/kgdbts/parameters/kgdbts To address the problem, the kgdb overflow handler needs to implement the same logic as the ptrace overflow handler call back with respect to updating the virtual copy of dr6. This will allow the kgdb do_debug() die notifier to properly handle the exception and the attached debugger, or kgdb test suite, will only receive a single notification.

Replace FSL USB platform code by simple platform driver for creation of FSL USB platform devices. The driver creates platform devices based on the information from USB nodes in the flat device tree. This is the replacement for old arch fsl_soc usb code removed by this patch. The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices. The new of-style driver additionaly instantiates USB OTG platform device, as the appropriate USB OTG driver will be added soon.

If the kernel's init section is merged back into the main memory region during boot (which it should since that is how we've laid out the kernel linker map), we want to make sure that these aren't counted as independent regions. Otherwise, if a large mapping is attempted which starts in the init region and extends into the main memory region, the access_ok func will deny it. This leads to weird messages during runtime like "unable to map xxx library" from the ldso but upon running the application again, everything works fine. So if the address of the end of the init region is the same as the start of the main memory region, simply enlarge the memory region to include the init region.

Many Blackfin parts group sets of pins into a single functional unit. This means you cannot use different pins within a group for different peripherals. Our resource conflict checking thus far has been limited to individual pins, so if someone tried to grab a different pin from the same group, it would be allowed while silently changing the other pins in the same group. One common example is the pin set PG12 - PG15 on BF51x parts. They may either be used with SPI0 (1st function), or they may be used with PTP/PWM/AMS3 (3rd function). Ideally, we'd like to use PG12 - PG14 for SPI0 while using PG15 with AMS3, but the hardware does not permit this. In the past, the software would allow the pins to be requested this way, but ultimately things like the Blackfin SPI driver would stop working when the hardware rerouted to a different peripheral.

Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do.
