2012-07-31ARM: 7479/1: mm: avoid NULL dereference when flushing gate_vma with VIVT cachesWill Deacon
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).

2012-07-31ARM: Fix undefined instruction exception handlingRussell King
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.

2012-07-31ARM: 7480/1: only call smp_send_stop() on SMPJavier Martinez Canillas
On reboot or poweroff (machine_shutdown()) a call to smp_send_stop() is made (to stop the others CPU's) when CONFIG_SMP=y. arch/arm/kernel/process.c: void machine_shutdown(void) { #ifdef CONFIG_SMP smp_send_stop(); #endif } smp_send_stop() calls the function pointer smp_cross_call(), which is set on the smp_init_cpus() function for OMAP processors. arch/arm/mach-omap2/omap-smp.c: void __init smp_init_cpus(void) { ... set_smp_cross_call(gic_raise_softirq); ... } But the ARM setup_arch() function only calls smp_init_cpus() if CONFIG_SMP=y && is_smp(). arm/kernel/setup.c: void __init setup_arch(char **cmdline_p) { ... #ifdef CONFIG_SMP if (is_smp()) smp_init_cpus(); #endif ... } Newer OMAP CPU's are SMP machines so omap2plus_defconfig sets CONFIG_SMP=y. Unfortunately on an OMAP UP machine is_smp() returns false and smp_init_cpus() is never called and the smp_cross_call() function remains NULL. If the machine is rebooted or powered off, smp_send_stop() will be called (since CONFIG_SMP=y) leading to the following error: [ 42.815551] Restarting system.

2012-07-31ARM: 7477/1: vfp: Always save VFP state in vfp_pm_suspend on UPColin Cross
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.

2012-07-31ARM: 7467/1: mutex: use generic xchg-based implementation for ARMv6+Will Deacon
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.

The CPU will endlessly spin at the end of machine_halt and machine_restart calls. However, this will lead to a soft lockup warning after about 20 seconds, if CONFIG_LOCKUP_DETECTOR is enabled, as system timer is still alive.
