get_system_type() is not thread-safe on OCTEON. It uses static data, also more dangerous issue is that it's calling cvmx_fuse_read_byte() every time without any synchronization. Currently it's possible to get processes stuck looping forever in kernel simply by launching multiple readers of /proc/cpuinfo: (while true; do cat /proc/cpuinfo > /dev/null; done) & (while true; do cat /proc/cpuinfo > /dev/null; done) & ...

Fix I/O space setup, so that on non-PCI systems using inb()/outb() won't crash the system. Some drivers may try to probe I/O space and for that purpose we can just allocate some normal memory initially. Drivers trying to reserve a region will fail early as we set the size to 0. If a real I/O space is present, the PCI/PCIe support code will re-adjust the values accordingly. Tested with EdgeRouter Lite by enabling CONFIG_SERIO_I8042 that caused the originally reported crash.

2013-06-21MIPS: Octeon: Don't clobber bootloader data structures.David Daney1-1/+1
Commit abe77f90dc (MIPS: Octeon: Add kexec and kdump support) added a bootmem region for the kernel image itself. The problem is that this is rounded up to a 0x100000 boundary, which is memory that may not be owned by the kernel. Depending on the kernel's configuration based size, this 'extra' memory may contain data passed from the bootloader to the kernel itself, which if clobbered makes the kernel crash in various ways. The fix: Quit rounding the size up, so that we only use memory assigned to the kernel.

2011-12-08MIPS: Handle initmem in systems with kernel not in add_memory_region() memDavid Daney1-8/+0
This patch addresses a couple of related problems: 1) The kernel may reside in physical memory outside of the ranges set by plat_mem_setup(). If this is the case, init mem cannot be reused as it resides outside of the range of pages that the kernel memory allocators control. 2) initrd images might be loaded in physical memory outside of the ranges set by plat_mem_setup(). The memory likewise cannot be reused. The patch doesn't handle this specific case, but the infrastructure is useful for future patches that do. The crux of the problem is that there are memory regions that need be memory_present(), but that cannot be free_bootmem() at the time of arch_mem_init(). We create a new type of memory (BOOT_MEM_INIT_RAM) for use with add_memory_region(). Then arch_mem_init() adds the init mem with this type if the init mem is not already covered by existing ranges. When memory is being freed into the bootmem allocator, we skip the BOOT_MEM_INIT_RAM ranges so they are not clobbered, but we do signal them as memory_present(). This way when they are later freed, the necessary memory manager structures have initialized and the Sparse allocater is prevented from crashing. The Octeon specific code that handled this case is removed, because the new general purpose code handles the case.
