* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] 8xx: Timebase frequency should not depend on bus-frequencyAnton Vorontsov2008-02-261-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m8xx_setup.c says: /* Force all 8xx processors to use divide by 16 processor clock. */ And at the same time it is using bus-frequency for calculating timebase. It is okay for most setups because bus-frequency is equal to clock-frequency. The problem emerges when cpu frequency is > 66MHz, quoting u-boot/cpu/mpc8xx/speed.c: if (gd->cpu_clk <= 66000000) { sccr_reg |= SCCR_EBDF00; /* bus division factor = 1 */ gd->bus_clk = gd->cpu_clk; } else { sccr_reg |= SCCR_EBDF01; /* bus division factor = 2 */ gd->bus_clk = gd->cpu_clk / 2; } So in case of cpu clock > 66MHz, bus_clk = cpu_clk / 2. An then, from Linux, we calculate timebase frequency as tb_freq = bus_clk / 16, that is cpu_clk / 2 / 16, which is wrong. This fixes the system time drifting problem on the EP885C board running at 133MHz. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] 8xx: Work around CPU15 erratum.Scott Wood2007-10-031-0/+16
| | | | | | | | | | | | | The CPU15 erratum on MPC8xx chips can cause incorrect code execution under certain circumstances, where there is a conditional or indirect branch in the last word of a page, with a target in the last cache line of the next page. This patch implements one of the suggested workarounds, by forcing a TLB miss whenever execution crosses a page boundary. This is done by invalidating the pages before and after the one being loaded into the TLB in the ITLB miss handler.

* [POWERPC] 8xx: Infrastructure code cleanup.Scott Wood2007-10-035-94/+22
| | | | | | | | | | | | | | | | | | | | | 1. Keep a global mpc8xx_immr mapping, rather than constantly creating temporary mappings. 2. Look for new fsl,cpm1 and fsl,cpm1-pic names. 3. Always reset the CPM when not using the udbg console; this is required in case the firmware initialized a device that is incompatible with one that the kernel is about to use. 4. Remove some superfluous casts and header includes. 5. Change a usage of IMAP_ADDR to get_immrbase(). 6. Use phys_addr_t, not uint, for dpram_pbase. 7. Various sparse-related fixes, such as __iomem annotations. 8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything useful beyond the generic cpuinfo handler. 9. Move prototypes for 8xx support functions from board files to sysdev/commproc.h. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as of_device, so only arch/powerpc stuff is capable to use it, which now implies only mpc885ads reference board. To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.

This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
