2007-06-20[POWERPC] PowerPC: Prevent data exception in kernel space (32-bit)Segher Boessenkool
The "is_exec" branch of the protection check in do_page_fault() didn't do anything on 32-bit PowerPC. So if a userland program jumps to a page with Linux protection flags "---p", all the tests happily fall through, and handle_mm_fault() is called, which in turn calls handle_pte_fault(), which calls update_mmu_cache(), which goes flush the dcache to a page with no access rights. Boom. This fixes it. Signed-off-by: Segher Boessenkool <segher@kernel.crashing.org> Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-06-14[POWERPC] Fix console output getting dropped on platforms without udbg_putcMilton Miller
Previously, registering this early console would just result in dropping early buffered printk output until a udbg_putc was registered. However, commit 69331af79cf29e26d1231152a172a1a10c2df511 clears the CON_PRINTBUFFER flag on the main console when a CON_BOOT (early) console has been registered, resulting in the buffered messages never being displayed to the user. This fixes the problem by making sure we don't register udbg_console on platforms that don't implement udbg_putc. Signed-off-by: Milton Miller <miltonm@bga.com> Acked-by: Mark A.

2007-06-14[POWERPC] Fix per-cpu allocation on oldworld SMP powermacsPaul Mackerras
The per-cpu area(a) for the secondary CPU(s) isn't getting allocated on old SMP powermacs that don't have the secondary CPU(s) listed in the device tree, as per-cpu areas are now only allocated for CPUs in the cpu_possible_map, and we aren't setting the bits for the secondary CPU(s) until smp_prepare_cpus(), which is after per-cpu allocation. Therefore this sets the bits for CPUs 1..3 in cpu_possible_map in pmac_setup_arch, so they get per-cpu data allocated. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-07[POWERPC] Fix building of COFF zImagesPaul Mackerras
The COFF zImage (for booting oldworld powermacs) wasn't being built correctly because the procedure descriptor in crt0.S for the zImage entry point wasn't declared as .globl, and therefore wasn't getting pulled in from wrapper.a by the linker. This adds the necessary .globl statement. Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-07[POWERPC] spufs: Fix error handling in spufs_fill_dir()Sebastian Siewior
The error path in spufs_fill_dir() is broken. If d_alloc_name() or spufs_new_file() fails, spufs_prune_dir() is getting called. At this time dir->inode is not set and a NULL pointer is dereferenced by mutex_lock().

Fix the race between checking for contexts on the runqueue and actually waking them in spu_deactive and spu_yield. The guts of spu_reschedule are split into a new helper called grab_runnable_context which shows if there is a runnable thread below a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating a specified priority and if yes removes if from the runqueue and uses it.

2007-06-02[POWERPC] Don't use HOSTCFLAGS in BOOTCFLAGSDavid Gibson
In the bootwrapper code for powerpc, we include HOSTCFLAGS into the BOOTCFLAGS used for building the zImage wrapper code. Since the wrapper code is not host code, this makes no sense. This patch removes the use of HOSTCFLAGS here, instead including directly into BOOTCFLAGS those flags from the normal kernel CFLAGS which also make sense in the bootwrapper code. In particular, this makes the bootwrapper use -msoft-float, preventing the compiler from generating floating point instructions. Previously, under some circumstances the compiler could generate floating point instructions in the bootwrapper which would cause exceptions on embedded CPUS which don't have floating point support.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

As a result of compiling all of the wrapper files for every platform now, the kernel build can fail for toolchains that don't support various op codes by default. An example of this building a 7xx platform with the ELD4.0 toolchain, is below: /tmp/ccYjhJoL.s: Assembler messages: /tmp/ccYjhJoL.s:42: Error: Unrecognized opcode: `mtdcr' /tmp/ccYjhJoL.s:43: Error: Unrecognized opcode: `mfdcr' make[1]: *** [arch/powerpc/boot/44x.o] Error 1 The following patch introduces additional CFLAGS for the 4xx specific files and fixes the kernel compile.

2007-05-17[POWERPC] Specify GNUTARGET on $(AR) invocationsSegher Boessenkool
Without this, some versions of GNU ar fail to create an archive index if the object files it is packing together are of a different object format than ar's default format (for example, binutils compiled to default to 64-bit, with 32-bit objects).

2007-05-17[POWERPC] Make sure device node type/name is not NULL on hot-added nodesBenjamin Herrenschmidt
Our device-tree unflattening code makes sure the name and type fields of a device-node are not NULL. However, the code for dynamically adding devices nodes which is used for pSeries hotplug for example didn't do it, potentially causing crashes in some code that assume it can always do things like strcmp on those.
