* ARM: 7479/1: mm: avoid NULL dereference when flushing gate_vma with VIVT cachesWill Deacon2012-07-311-2/+6
| | | | | | | | | | | | | | | | | | | | | The vivt_flush_cache_{range,page} functions check that the mm_struct of the VMA being flushed has been active on the current CPU before performing the cache maintenance. The gate_vma has a NULL mm_struct pointer and, as such, will cause a kernel fault if we try to flush it with the above operations. This happens during ELF core dumps, which include the gate_vma as it may be useful for debugging purposes. This patch adds checks to the VIVT cache flushing functions so that VMAs with a NULL mm_struct are flushed unconditionally (the vectors page may be dirty if we use it to store the current TLS pointer).

* ARM: Fix undefined instruction exception handlingRussell King2012-07-314-62/+92
| | | | | | | | | | | | | | | | | | | | | | | | | While trying to get a v3.5 kernel booted on the cubox, I noticed that VFP does not work correctly with VFP bounce handling. This is because of the confusion over 16-bit vs 32-bit instructions, and where PC is supposed to point to. The rule is that FP handlers are entered with regs->ARM_pc pointing at the _next_ instruction to be executed. However, if the exception is not handled, regs->ARM_pc points at the faulting instruction. This is easy for ARM mode, because we know that the next instruction and previous instructions are separated by four bytes. This is not true of Thumb2 though. Since all FP instructions are 32-bit in Thumb2, it makes things easy. We just need to select the appropriate adjustment. Do this by moving the adjustment out of do_undefinstr() into the assembly code, as only the assembly code knows whether it's dealing with a 32-bit or 16-bit instruction.

* ARM: 7480/1: only call smp_send_stop() on SMPJavier Martinez Canillas2012-07-311-1/+2

* ARM: 7477/1: vfp: Always save VFP state in vfp_pm_suspend on UPColin Cross2012-07-311-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | vfp_pm_suspend should save the VFP state in suspend after any lazy context switch. If it only saves when the VFP is enabled, the state can get lost when, on a UP system: Thread 1 uses the VFP Context switch occurs to thread 2, VFP is disabled but the VFP context is not saved Thread 2 initiates suspend vfp_pm_suspend is called with the VFP disabled, and the unsaved VFP context of Thread 1 in the registers Modify vfp_pm_suspend to save the VFP context whenever vfp_current_hw_state is not NULL. Includes a fix from Ido Yariv <ido@wizery.com>, who pointed out that on SMP systems, the state pointer can be pointing to a freed task struct if a task exited on another cpu, fixed by using #ifndef CONFIG_SMP in the new if clause.

* ARM: 7467/1: mutex: use generic xchg-based implementation for ARMv6+Will Deacon2012-07-311-115/+4
| | | | | | | | | | | | | | | | | | | | | | | The open-coded mutex implementation for ARMv6+ cores suffers from a severe lack of barriers, so in the uncontended case we don't actually protect any accesses performed during the critical section. Furthermore, the code is largely a duplication of the ARMv6+ atomic_dec code but optimised to remove a branch instruction, as the mutex fastpath was previously inlined. Now that this is executed out-of-line, we can reuse the atomic access code for the locking (in fact, we use the xchg code as this produces shorter critical sections). This patch uses the generic xchg based implementation for mutexes on ARMv6+, which introduces barriers to the lock/unlock operations and also has the benefit of removing a fair amount of inline assembly code.

Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.

Without this programming, they will prevent the rest of the chip from entering full chip idle. To implement the idle programming cleanly, this will take some coordination between maintainers. This is likely to take some time, so it is probably best to leave this for 3.6 or 3.7. So, in the meantime, prevent these IP blocks from being registered. Later, once the appropriate support is available, this patch can be reverted. This second version comments out the IP block data since Benoît didn't like removing it.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Basic suspend/resume is fixed by ensuring that the PGSR registers are set correctly before sleep mode is entered. In particular four of the active low resets need to be driven high while in sleep mode, otherwise the unit resets itself instead of suspending. Another problem was that the PCFR_GPROD bit is set by the HTC bootloader; this caused GPIO reset (i.e. the reset button) to fail immediately after returning from sleep mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM with the 2-level page table format, a PMD entry is represented by two consecutive section entries covering 2MB of virtual space. However, static mappings always were allowed to use separate 1MB section entries. This means in practice that a static mapping may create half populated PMDs via create_mapping(). Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc region) those static mappings are located in the vmalloc area. We must ensure no such half populated PMDs are accessible once vmalloc() or ioremap() start looking at the vmalloc area for nearby free virtual address ranges, or various things leading to a kernel crash will happen.

The kallsyms data is built in two passes by first linking the kernel without it, and then linking the kernel again with the symbols included. Normally, this just shifts the symbols, without changing their order, and the compression used by the kallsyms gives the same result. On non SMP, the per CPU data is empty. Depending on the where the alignment ends up, it can come out as either: +-------------------+ | last text segment | +-------------------+ /* padding */ +-------------------+ <- L1_CACHE_BYTES alignemnt | per cpu (empty) | +-------------------+ __per_cpu_end: /* padding */ __data_loc: +-------------------+ <- THREAD_SIZE alignment | data | +-------------------+ or +-------------------+ | last text segment | +-------------------+ /* padding */ +-------------------+ <- L1_CACHE_BYTES alignemnt | per cpu (empty) | +-------------------+ __per_cpu_end: /* no padding */ __data_loc: +-------------------+ <- THREAD_SIZE alignment | data | +-------------------+ if the alignment satisfies both. Because symbols that have the same address are sorted by 'nm -n', the second case will be in a different order than the first case. This changes the compression, changing the size of the kallsym data, causing the build failure. The KALLSYMS_EXTRA_PASS=1 workaround usually works, but it is still possible to have the alignment change between the second and third pass. It's probably even possible for it to never reach a fixedpoint. The problem only occurs on non-SMP, when the per-cpu data is empty, and when the data segment has alignment (and immediately follows the text segments). Fix this by only including the per_cpu section on SMP, when it is not empty. Signed-off-by: David Brown <davidb@codeaurora.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

By removing the static in the header file, it created a duplicate definition in the .c and the .h files, resuling in a build error: /work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.c:102:111: error: redefinition of 'board_onenand_init' /work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.h:56:51: note: previous definition of 'board_onenand_init' was here make[2]: *** [arch/arm/mach-omap2/board-flash.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [arch/arm/mach-omap2] Error 2 make: *** [sub-make] Error 2 Fix this by removing the duplicate dummy entry from the C file.
