2010-03-12m68knommu: use generic ptrace_resume codeChristoph Hellwig
Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. m68knommu already defines the nessecary user_enable_single_step and user_disable_single_step functions for this. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.

This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix.

2010-03-12ptrace: move user_enable_single_step & co prototypes to linux/ptrace.hChristoph Hellwig
While in theory user_enable_single_step/user_disable_single_step/ user_enable_blockstep could also be provided as an inline or macro there's no good reason to do so, and having the prototype in one places keeps code size and confusion down. Roland said: The original thought there was that user_enable_single_step() et al might well be only an instruction or three on a sane machine (as if we have any of those!), and since there is only one call site inlining would be beneficial. But I agree that there is no strong reason to care about inlining it. As to the arch changes, there is only one thought I'd add to the record. It was always my thinking that for an arch where PTRACE_SINGLESTEP does text-modifying breakpoint insertion, user_enable_single_step() should not be provided. That is, arch_has_single_step()=>true means that there is an arch facility with "pure" semantics that does not have any unexpected side effects. Inserting a breakpoint might do very unexpected strange things in multi-threaded situations. Aside from that, it is a peculiar side effect that user_{enable,disable}_single_step() should cause COW de-sharing of text pages and so forth. For PTRACE_SINGLESTEP, all these peculiarities are the status quo ante for that arch, so having arch_ptrace() itself do those is one thing. But for building other things in the future, it is nicer to have a uniform "pure" semantics that arch-independent code can expect. OTOH, all such arch issues are really up to the arch maintainer. As of today, there is nothing but ptrace using user_enable_single_step() et al so it's a distinction without a practical difference. If/when there are other facilities that use user_enable_single_step() and might care, the affected arch's can revisit the question when someone cares about the quality of the arch support for said new facility.

2010-03-12Add generic sys_ipc wrapperChristoph Hellwig
Add a generic implementation of the ipc demultiplexer syscall. Except for s390 and sparc64 all implementations of the sys_ipc are nearly identical. There are slight differences in the types of the parameters, where mips and powerpc as the only 64-bit architectures with sys_ipc use unsigned long for the "third" argument as it gets casted to a pointer later, while it traditionally is an "int" like most other paramters. frv goes even further and uses unsigned long for all parameters execept for "ptr" which is a pointer type everywhere. The change from int to unsigned long for "third" and back to "int" for the others on frv should be fine due to the in-register calling conventions for syscalls (we already had a similar issue with the generic sys_ptrace), but I'd prefer to have the arch maintainers looks over this in details. Except for that h8300, m68k and m68knommu lack an impplementation of the semtimedop sub call which this patch adds, and various architectures have gets used - at least on i386 it seems superflous as the compat code on x86-64 and ia64 doesn't even bother to implement it.

2010-03-11OMAP4: fix temporary hacks that break multi-omap PMKevin Hilman
When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4 will be true and prevent included code from building/running for OMAP2/3 as well. This problem exists in io.c where some hwmod/PM/SDRC init code is prevented from running even on OMAP2/3 when OMAP4 is included in a multi-OMAP build. A quick glance suggests that this #ifndef is no longer needed in most of the cases. In the remaining cases, the function is wrapped with "if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized out for OMAP4-only builds. Note that this is only a short-term fix. Longer-term, OMAP4 needs to create init functions for SDRC and hwmod late-init.

2010-03-11OMAP2: cpu_is_omap2*: fix compile-time removal of unused codeKevin Hilman
Currently if omap2420 is defined but not omap2430, cpu_is_omap2430() is still defined as a macro, instead of #define'd to zero. This results in conditional cpu_is_omap2430() code still being compiled, and leads to possible compile/link errors. In particular for hwmod init. To fix, add extra #ifdefs to CPU check macros to ensure that the is_omap* macros are zero for each OMAP2 if they are not configured into the kernel.

2010-03-11omap: pass the reboot command to the boot loaderAaro Koskinen
This patch follows the commit be093beb608edf821b45fe00a8a080fb5c6ed4af by Russell King: OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). The patch adds the missing parameter to omap1_arch_reset() and omap_prcm_arch_reset(), and modifies the latter to pass the reboot command parameter to the boot loader instead of reboot mode (which is for kernel internal use only and cannot be modified by the userspace).

Might as well merge it while at it to make it more usable as we're using this to test the multi-omap booting between V6 and V7 ARMs. Also, anybody using n8x0 with a current kernel will most likely want to mount root on the MMC instead of the onenand to keep the Maemo install intact.

2010-03-11perf, x86: Fix hw_perf_enable() event assignmentPeter Zijlstra
What happens is that we schedule badly like: <...>-1987 [019] 280.252808: x86_pmu_start: event-46/1300c0: idx: 0 <...>-1987 [019] 280.252811: x86_pmu_start: event-47/1300c0: idx: 1 <...>-1987 [019] 280.252812: x86_pmu_start: event-48/1300c0: idx: 2 <...>-1987 [019] 280.252813: x86_pmu_start: event-49/1300c0: idx: 3 <...>-1987 [019] 280.252814: x86_pmu_start: event-50/1300c0: idx: 32 <...>-1987 [019] 280.252825: x86_pmu_stop: event-46/1300c0: idx: 0 <...>-1987 [019] 280.252826: x86_pmu_stop: event-47/1300c0: idx: 1 <...>-1987 [019] 280.252827: x86_pmu_stop: event-48/1300c0: idx: 2 <...>-1987 [019] 280.252828: x86_pmu_stop: event-49/1300c0: idx: 3 <...>-1987 [019] 280.252829: x86_pmu_stop: event-50/1300c0: idx: 32 <...>-1987 [019] 280.252834: x86_pmu_start: event-47/1300c0: idx: 1 <...>-1987 [019] 280.252834: x86_pmu_start: event-48/1300c0: idx: 2 <...>-1987 [019] 280.252835: x86_pmu_start: event-49/1300c0: idx: 3 <...>-1987 [019] 280.252836: x86_pmu_start: event-50/1300c0: idx: 32 <...>-1987 [019] 280.252837: x86_pmu_start: event-51/1300c0: idx: 32 *FAIL* This happens because we only iterate the n_running events in the first pass, and reset their index to -1 if they don't match to force a re-assignment. Now, in our RR example, n_running == 0 because we fully unscheduled, so event-50 will retain its idx==32, even though in scheduling it will have gotten idx=0, and we don't trigger the re-assign path. The easiest way to fix this is the below patch, which simply validates the full assignment in the second pass.

2010-03-11microblaze: Fix dma alloc and free coherent dma functionsMichal Simek
We have to use consistent code to be able to do coherent dma function. In consistent code is used cache inhibit page mapping. Xilinx reported that there is bug in Microblaze for WB and d-cache_always use option. Microblaze 7.30.a should be first version where is this bug removed.

2010-03-11microblaze: Add consistent codeMichal Simek
Remove ancient Kconfig option for consistent code. MMU uses cache inhibit pages. noMMU uses UNCACHE SHADOW feature where is used double ram size. For example: Physical ram is 256MB and cache are setup to cover the same size. But if you setup in HW that size is 512MB and cache covers 256MB than you can use adresses from 256-512MB without caches and correspond with 0-256MB with cache. That's why I am using dcache base/high addresses to find out uncache area. Signed-off-by: Michal Simek <monstr@monstr.eu>
