2014-05-28scsi/NCR5380: fix dprintk macro usage and definitionFinn Thain
There are three implementations of the core NCR5380 driver and three sets of debugging macro definitions. And all three implementations use the NCR5380.h header as well. Two of the definitions of the dprintk macro accept a variable argument list whereas the third does not. Standardize on the variable argument list.

2014-05-28scsi/NCR5380: fix build failures when debugging is enabledFinn Thain
The change from cmd->target to cmd->device->id was apparently the purpose of commit a7f251228390e87d86c5e3846f99a455517fdd8e in kernel/git/tglx/history.git but some instances have been missed. Also fix the "NDEBUG_LAST_WRITE_SENT" and "NDEBUG_ALL" typo's. Also fix some format strings (%ul becomes %lu) that caused compiler warnings.

2014-05-28scsi/NCR5380: use NCR5380_dprint() instead of NCR5380_print()Finn Thain
Only the NCR5380_dprint() macro should invoke the NCR5380_print() function. That's why NCR5380.c only defines the function #if NDEBUG. Use the standard macro. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Acked-by: Sam Creasey <sammy@sammy.net> Signed-off-by: Christoph Hellwig <hch@lst.de>

2014-05-28MIPS: ptrace: Avoid smp_processor_id() in preemptible codeAlex Smith
ptrace_{get,set}_watch_regs access current_cpu_data to get the watch register count/masks, which calls smp_processor_id(). However they are run in preemptible context and therefore trigger warnings like so: [ 6340.092000] BUG: using smp_processor_id() in preemptible [00000000] code: gdb/367 [ 6340.092000] caller is ptrace_get_watch_regs+0x44/0x220 Since the watch register count/masks should be the same across all CPUs, use boot_cpu_data instead. Note that this may need to change in future should a heterogenous system be supported where the count/masks are not the same across all CPUs (the current code is also incorrect for this scenario - current_cpu_data here would not necessarily be correct for the CPU that the target task will execute on).

2014-05-28s390/lowcore: reserve 96 bytes for IRB in lowcoreChristian Borntraeger
The IRB might be 96 bytes if the extended-I/O-measurement facility is used. This feature is currently not used by Linux, but struct irb already has the emw defined. So let's make the irb in lowcore match the size of the internal data structure to be future proof. We also have to add a pad, to correctly align the paste. The bigger irb field also circumvents a bug in some QEMU versions that always write the emw field on test subchannel and therefore destroy the paste definitions of this CPU. Running under these QEMU version broke some timing functions in the VDSO and all users of these functions, e.g. some JREs.

2014-05-28m68k: Multi-platform EARLY_PRINTKFinn Thain
Make the boot console available to more m68k platforms by leveraging the head.S debug console. The boot console is enabled by the "earlyprintk" command line argument which is how most other architectures do this. This is a change of behaviour for the Mac but does not negatively impact the common use-case which is not debugging. This is also a change of behaviour for other platforms because it means the serial port stays quiet when CONFIG_EARLY_PRINTK is not enabled. This is also an improvement for the common use-case.

With the recommended twl4030 configuration added, we can now add board specific changes as modifications to the recommended configuration. Note that the data is private to this driver, and the data must always have a NULL resource in the sentinel.

2014-05-28mfd: twl4030-power: Add recommended idle configurationTony Lindgren
These settings are based on the "Recommended Sleep Sequences for the Zoom Platform". The settings assume most of the regulators are under control of Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as Linux cannot do it. For any board specific changes to these, let's patch them in as changes to the generic data in the follow-up patches. This keeps the board specific changes small. Note that this does not consider the twl5030 errata 27 and 28. That can be added later on after it has been tested. For more information about errata 27 and 28.

2014-05-28mfd: twl4030-power: Add generic reset configurationTony Lindgren
The twl4030 PMIC needs to be configured properly for things like warm reset and deeper idle states so the PMIC manages the regulators properly based on the hardware triggers from the SoC. Earlier we have configured twl4030 using platform data, but we want to do it for device tree based booting also. In some cases configuring twl4030 is needed for things to work. For example, when rebooting an OMAP3530 at 125 MHz, it hangs. With this patch, TWL4030 will be reset when a warm reset occures, and OMAP3530 does not hang on reboot. Let's add device tree support and configure things for warm reset as the default when compatible = "ti,twl4030-power". More complicated configurations can be added to the driver based on other compatible flags. Note we now also make the pdata const like it should be. This allows use it for match->data with the device tree related functions. Based on earlier patch by Matthias Brugger <matthias.bgg@gmail.com> and Lesly A M <leslyam@ti.com>.

2014-05-28mtd: nand: r852: correct write_buf loop boundsBrian Norris
The two loops in r852_write_buf() are designed to handle 4-byte-aligned and then 1-byte-aligned portions, respectively. However, there are two issues: (1) The first loop will only terminate if 'len' is a multiple of 4 (2) The second loop will never terminate if it runs at least once Rewrite these loops as they were probably intended. Compile tested only. Issues pointed out by Coverity Scan. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Cc: Maxim Levitsky <maximlevitsky@gmail.com>

On m86k, and maybe a few other architectures, we get this kind of warning, due to misuse of volatile: drivers/mtd/maps/sc520cdp.c: In function 'sc520cdp_setup_par': >> drivers/mtd/maps/sc520cdp.c:223:2: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [enabled by default] arch/m68k/include/asm/raw_io.h:22:13: note: expected 'void *' but argument is of type 'volatile long unsigned int *' Rather than annotating the variable declaration, let's just use the proper accessors, which add the 'volatile' qualifier to the operation.
