[POWERPC] fsl_lbc: implement few UPM routines Freescale UPM can be used to adjust localbus timings or to generate orbitrary, pre-programmed "patterns" on the external Localbus signals. This patch implements few routines so drivers could work with UPMs in safe and generic manner. So far there is just one user of these routines: Freescale UPM NAND driver.

P4080/eLBC: Make Freescale elbc interrupt common to elbc devices Move Freescale elbc interrupt from nand driver to elbc driver. Then all elbc devices can use the interrupt instead of ONLY nand.

powerpc: fix fsl_upm nand driver modular build The fsl_upm nand driver fails to build because fsl_lbc_lock isn't exported, the lock is needed by the inlined fsl_upm_run_pattern() function: ERROR: "fsl_lbc_lock" [drivers/mtd/nand/fsl_upm.ko] undefined! Dave Jones purposed to export the lock, but it is better to just uninline the fsl_upm_run_pattern(). When uninlined we also no longer need the exported fsl_lbc_regs, and both fsl_lbc_lock and fsl_lbc_regs could be marked static. While at it, also add some missing includes that we should have included explicitly.

[POWERPC] fsl_lbc: implement few UPM routines Freescale UPM can be used to adjust localbus timings or to generate orbitrary, pre-programmed "patterns" on the external Localbus signals. This patch implements few routines so drivers could work with UPMs in safe and generic manner. So far there is just one user of these routines: Freescale UPM NAND driver.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

P4080/eLBC: Make Freescale elbc interrupt common to elbc devices Move Freescale elbc interrupt from nand driver to elbc driver. Then all elbc devices can use the interrupt instead of ONLY nand. For former nand driver, it had the two functions: 1. detecting nand flash partitions; 2. registering elbc interrupt. Now, second function is removed to fsl_lbc.c.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

powerpc: use subsys_initcall for Freescale Local Bus The FSL_SOC option is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of subsys_initcall (which makes sense for bus code) will thus change this registration from level 6-device to level 4-subsys (i.e. slightly earlier). However no observable impact of that small difference has been observed during testing, or is expected.
