The sysdev.h file should not be needed by any in-kernel code, so remove the .h file from these random files that seem to still want to include it. The sysdev code will be going away soon, so this include needs to be removed no matter what.

The set_vpp() method provided by physmap passes a map_info back to the platform code, which has little relevance as far as the platform is concerned (this parameter is completely unused). Instead, pass the platform_device, which can be used in the pismo driver to retrieve some important information in a nicer way, instead of the hack that was in place. The empty set_vpp function in board-at572d940hf_ek.c is left untouched, as the board/SoC is scheduled for removal.

Rather than each platform providing its own function to adjust the zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this adjustment. This ensures that the actual DMA zone size and the ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with each other, and moves this complexity out of the platform code.

This is a number of basic fixes to the PB1176 that makes it tick properly: - Detect MMC insertion/removal even when PL061 GPIO is not compiled in. The register to read this status directly is removed on the PB1176. - Define the UART3 on the DevChip (where is actually is) and define the new UART4 serial port on the FPGA. - Also define the clocks for these two UARTs apropriately. - Remove the false notion that the PB1176 should have its CLCD on the ISSP, this is not the case, it is in the DevChip. - Remove the defintions and the previously commented-out PL081 DMAC. As confirmed by mail this was found to be broken on the PB1176 board and removed from the subsequent FPGA images.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The RealView PBX board has two 512MB blocks of memory - one at 0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g. framebuffer). This patch adds the sparsemem definitions to allow the use of all the memory split as follows: 256MB @ 0x00000000 (ZONE_DMA) 512MB @ 0x20000000 (ZONE_NORMAL) 256MB @ 0x80000000 (ZONE_NORMAL) Signed-off-by: NCatalin Marinas <catalin.marinas@arm.com>
