由 Steven King 提交于
These changes based on work by Steven King <sfking@fdwdc.com> to support the i2c hardware modules on ColdFire SoC family devices. This is the per SoC hardware support. Contains a common platform device setup. Each of the SoC family members tends to have some minor local setup required to initialize the module. But all ColdFire family members use the same i2c hardware module. This i2c hardware module is the same as used in the Freescale iMX ARM based family of SoC devices. Steven's original patches were based on using a new and different i2c-coldfire.c driver. But this is not neccessary as we can use the existing Linux i2c-imx.c driver with no change required to it. And this patch is now based on using the existing i2c-imx driver. This patch only contains the ColdFire platform changes.

With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: NJarod Wilson <jarod@redhat.com> Signed-off-by: NDavid S.

When doing an nmi backtrace of many cores, most of which are idle, the output is a little overwhelming and very uninformative. Suppress messages for cpus that are idling when they are interrupted and just emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN". We do this by grouping all the cpuidle code together into a new .cpuidle.text section, and then checking the address of the interrupted PC to see if it lies within that section. This commit suitably tags x86 and tile idle routines, and only adds in the minimal framework for other architectures.

Our local m68k architecture dump_fpu() is conditionally compiled in on CONFIG_FPU. That is OK for all existing MMU enabled CPU types, but won't handle the case for some ColdFire SoC CPU parts that we want to support that have no FPU hardware. dump_fpu() is expected to be present by the ELF loader, so we must always have it available and exported. Remove the conditional and reorganize the dump_fpu hard FPU code path to let the compiler remove code when not needed.

The ACR registers of the ColdFire define at a macro level what regions of the addresses space should have caching or other attribute types applied. Currently for the MMU enabled setups we map the interal IO peripheral addres space as uncachable based on the define for the MBAR address (CONFIG_MBAR). Not all ColdFire SoC use a programmable MBAR register address. Some parts have fixed addressing for their internal peripheral registers. Generalize the way we get the internal peripheral base address so all types can be accomodated in the ACR definitions. Each ColdFire SoC type now sets its IO memory base and size definitions (which may be based on MBAR) which are then used in the ACR definitions. Signed-off-by: NGreg Ungerer <gerg@linux-m68k.org>

Create a new machine type for platforms based around the ColdFire 5441x SoC family. Set that machine type on startup when building for this platform type. Currently the ColdFire head.S hard codes a M54xx machine type at startup - since that is the only platform type currently supported with MMU enabled.

Move the selection of CONFIG_FPU to each CPU type configuration. Currently for m68k we have a global set of CONFIG_FPU based on if CONFIG_MMU is enabled or not. There is at least one CPU family we support (m5441x) that has an MMU but has no FPU hardware. So we need to be able to have CONFIG_MMU set and CONFIG_FPU not set. Whether we build for a CPU with MMU enabled or not doesn't change the fact that it has FPU hardware support. Our current non-MMU builds have never had CONIG_FPU enabled - and in fact the kernel will not compile with that set and CONFIG_MMU not set at the moment. It is easy enough to fix this - but it would involve a structure change to sigcontext.h, and that is a user space exported header (so ABI change). This change makes no configuration visible changes, and all configs end up with the same configuration settings as before.

The early setup code for the ColdFire 53xx platform accesses variables before the RAM and other system initialization steps may have taken place. Currently it has 2 global variables that will end up in the bss section that are accessed during this early setup. There is a special static RAM stack setup at this time, but not necessarily the RAM where kernel data sections will end up. Even on system setups where RAM is setup by a boot loader the access to the early setup variables is before the BSS section has been initialized. This can potentially corrupt a ram loaded root filesystem that sits in that memory area before it has been moved. These 2 variables are not used at all after being set, and can just be removed.

On no-MMU systems the application a5 register can be overwitten with the address of the process data segment when processing application signals. For flat format applications compiled with full absolute relocation this effectively corrupts the a5 register on signal processing - and this very quickly leads to process crash and often takes out the whole system with a panic as well. This has no effect on flat format applications compiled with the more common PIC methods (such as -msep-data). These format applications reserve a5 for the pointer to the data segment anyway - so it doesn't change it. A long time ago the a5 register was used in the code packed into the user stack to enable signal return processing. And so it had to be restored on end of signal cleanup processing back to the original a5 user value. This was historically done by saving away a5 in the sigcontext structure. At some point (a long time back it seems) the a5 restore process was changed and it was hard coded to put the user data segment address directly into a5. Which is ok for the common PIC compiled application case, but breaks the full relocation application code. We no longer use this type of signal handling mechanism and so we don't need to do anything special to save and restore a5 at all now. So remove the code that hard codes a5 to the address of the user data segment. Signed-off-by: NGreg Ungerer <gerg@linux-m68k.org>

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value.

Even after recent changes to support running flat format executables on MMU enabled systems (by nicolas.pitre@linaro.org) they still failed to run on m68k/ColdFire MMU enabled systems. On trying to run a flat format binary the application would immediately crash with a SIGSEGV. Code to setup the D5 register with the base of the application data region was only in the non-MMU code path, so it was not being set for the MMU enabled case. Flat binaries on m68k/ColdFire use this to support GOT/PIC flat built application code. Fix this so that D5 is always setup when loading/running a bFLT executable on m68k systems.

This is the third version of the patchset previously sent [1]. I have basically only rebased it on top of 4.7-rc1 tree and dropped "dm: get rid of superfluous gfp flags" which went through dm tree. I am sending it now because it is tree wide and chances for conflicts are reduced considerably when we want to target rc2. I plan to send the next step and rename the flag and move to a better semantic later during this release cycle so we will have a new semantic ready for 4.8 merge window hopefully. Motivation: While working on something unrelated I've checked the current usage of __GFP_REPEAT in the tree. It seems that a majority of the usage is and always has been bogus because __GFP_REPEAT has always been about costly high order allocations while we are using it for order-0 or very small orders very often. It seems that a big pile of them is just a copy&paste when a code has been adopted from one arch to another. I think it makes some sense to get rid of them because they are just making the semantic more unclear. Please note that GFP_REPEAT is documented as * __GFP_REPEAT: Try hard to allocate the memory, but the allocation attempt * _might_ fail. This depends upon the particular VM implementation. while !costly requests have basically nofail semantic. So one could reasonably expect that order-0 request with __GFP_REPEAT will not loop for ever. This is not implemented right now though. I would like to move on with __GFP_REPEAT and define a better semantic for it. $ git grep __GFP_REPEAT origin/master | wc -l 111 $ git grep __GFP_REPEAT | wc -l 36 So we are down to the third after this patch series. The remaining places really seem to be relying on __GFP_REPEAT due to large allocation requests. This still needs some double checking which I will do later after all the simple ones are sorted out. I am touching a lot of arch specific code here and I hope I got it right but as a matter of fact I even didn't compile test for some archs as I do not have cross compiler for them. Patches should be quite trivial to review for stupid compile mistakes though. The tricky parts are usually hidden by macro definitions and thats where I would appreciate help from arch maintainers. [1] http://lkml.kernel.org/r/1461849846-27209-1-git-send-email-mhocko@kernel.org This patch (of 19): __GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations. Yet we have the full kernel tree with its usage for apparently order-0 allocations. This is really confusing because __GFP_REPEAT is explicitly documented to allow allocation failures which is a weaker semantic than the current order-0 has (basically nofail). Let's simply drop __GFP_REPEAT from those places. This would allow to identify place which really need allocator to retry harder and formulate a more specific semantic for what the flag is supposed to do actually.
