2013-12-30m68k: Convert arch/m68k/kernel/traps.c to pr_*()Geert Uytterhoeven1-131/+101
Also fix a few printf-style formats, to get rid of the following compiler warnings when DEBUG is enabled: arch/m68k/kernel/traps.c: In function ‘access_error060’: arch/m68k/kernel/traps.c:166: warning: format ‘%d’ expects type ‘int’, but argument 2 has type ‘long unsigned int’ arch/m68k/kernel/traps.c: In function ‘bus_error030’: arch/m68k/kernel/traps.c:568: warning: format ‘%#lx’ expects type ‘long unsigned int’, but argument 2 has type ‘void *’ arch/m68k/kernel/traps.c:682: warning: format ‘%#lx’ expects type ‘long unsigned int’, but argument 2 has type ‘void *’ Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2013-12-30m68k/mm: Check for mm != NULL in do_page_fault() debug codeGeert Uytterhoeven1-2/+1
When DEBUG is enabled, do_page_fault() may dereference a NULL pointer, causing recursive bus errors. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-12-30m68k/defconfig: Disable /sbin/hotplug fork-bomb by defaultGeert Uytterhoeven12-12/+0

2013-12-08m68k/atari: Hide RTC_PORT() macro from rtc-cmosGeert Uytterhoeven1-5/+5
Rename RTC_PORT() to ATARI_RTC_PORT(), as the rtc-cmos RTC driver uses the presence of this macro to enable support for the second NVRAM bank, which Atari doesn't have ("Unable to handle kernel access at virtual address 00ff8965"). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-12-08m68k/amiga,atari: Fix specifying multiple debug= parametersGeert Uytterhoeven2-6/+18
Since commit d6713b4091a99fa2af2fabdcd2f3fb97f32ecf2e ("m68k: early parameter support"), the user can specify multiple debug consoles using the "debug=" kernel command line parameter. However, as there's only a single struct console object, which is reused, it would actually register the same console object multiple times, causing the following warning: WARNING: CPU: 0 PID: 0 at kernel/printk/printk.c:2233 register_console+0x36/ console 'debug0' already registered Make sure to register the console object only once, to avoid the warning. Note that still only one console (the one corresponding to the last "debug=" parameter) will be active at the same time, as the .write() method of the already registered console object is overwritten by a subsequent "debug=" parameter.

2013-12-08m68k/defconfig: Use ext4 for ext2/ext3 file systemsGeert Uytterhoeven12-48/+0
This reduces the kernel image size by ca. 160 KiB. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-12-08m68k: Add support to export bootinfo in procfsGeert Uytterhoeven5-0/+102
Add optional support to export the bootinfo used to boot the kernel in a "bootinfo" file in procfs. This is useful with kexec. This is based on the similar feature for ATAGS on ARM. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2013-12-08m68k/mac: Mark Mac IIsi ADB driver BROKENGeert Uytterhoeven1-1/+1
As reported by Finn Thain, the Mac IIsi ADB driver should be disabled because it will crash. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26m68k/amiga: Provide mach_random_get_entropy()Geert Uytterhoeven1-0/+10
Use the beam position registers, which provide at least 17 bits of data changing at 1.79 MHz. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26m68k: Add infrastructure for machine-specific random_get_entropy()Geert Uytterhoeven2-0/+14
On m68k, get_cycles() (the default implementation for random_get_entropy()) always returns zero, providing no entropy for the random driver. Add a hook where platforms can provide their own implementation, and wire it up in the infrastructure provided by commit 61875f30daf60305712e25b209ef41ced2635bad ("random: allow architectures to optionally define random_get_entropy()"). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26m68k/atari: Call paging_init() before nf_init()Geert Uytterhoeven1-2/+2
nf_init() uses virt_to_phys(), which depends on m68k_memoffset being set and module_fixup() having been called, but this is only done in paging_init(). Hence call paging_init() before nf_init(). This went unnoticed, as virt_to_phys() is a no-op on Atari, unless you start fiddling with the memory blocks in the bootinfo manually. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2013-11-26m68k/UAPI: Move generic definitions to <asm/bootinfo.h>Geert Uytterhoeven6-95/+85
Move generic definitions used by bootstraps to uapi/asm/bootinfo.h: - Machine types, - CPU, FPU, and MMU types, - struct mem_info. Keep a copy of struct mem_info for in-kernel use, and rename it to struct m68k_mem_info, as the exported one will be modified later. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2013-11-26m68k/mac: Move struct mac_booter_data to <asm/macintosh.h>Geert Uytterhoeven3-41/+23
struct mac_booter_data is no longer part of the bootinfo API, hence move it from <asm/bootinfo.h> to <asm/macintosh.h>, dropping all unused fields in the process. Also remove the no longer used mac_booter_data pointer from head.S. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26m68k: Drop remainings and API of BOOTINFO_COMPAT_1_0Geert Uytterhoeven3-114/+0
Drop remainings and API for backwards compatibility with bootinfo interface version 1.0. This was used when booting a 2.1.x or newer kernel on Amiga, Atari, or Mac using a bootstrap for kernel 2.0.x. Everybody upgraded his bootstrap a long time ago, so this can go. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2013-11-26m68k: The bootinfo is located right after the kernelGeert Uytterhoeven3-3/+3
Since the introduction of init sections (which are located after BSS), the bootinfo is no longer located right after the BSS, but after all kernel sections. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26block/z2ram: Remove duplicate external declarationsGeert Uytterhoeven1-3/+0

2013-11-26zorro/UAPI: Use proper types (endianness/size) in <linux/zorro.h>Geert Uytterhoeven8-46/+72
Fix member definitions for non-native userspace handling: - All multi-byte values are big-endian, hence use __be*, - All pointers are 32-bit pointers under AmigaOS, but unused (except for cd_BoardAddr) under Linux, hence use __be32. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro/UAPI: Disintegrate include/linux/zorro*.hGeert Uytterhoeven5-102/+119
The Zorro definitions and device IDs are used by bootstraps, hence they should be exported through UAPI. Unfortunately zorro.h was never marked for export when headers_install was introduced, so it was forgotten during the big UAPI disintegration. In addition, the removal of zorro_ids.h had been sneaked into commit 7e7a43c32a8970ea2bfc3d1af353dcb1a9237769 ("PCI: don't export device IDs to userspace") before, so it was also forgotten. Split off and export the Zorro definitions used by bootstraps. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro: ZTWO_VADDR() should return "void __iomem *"Geert Uytterhoeven17-22/+22
ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should return "void __iomem *" instead of "unsigned long". This allows to drop several casts, but requires adding a few casts to accomodate legacy driver frameworks that store "unsigned long" I/O addresses. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro: Let the driver core handle device enumerationGeert Uytterhoeven2-7/+8
Filling in dev_name of the Zorro bus type and dev.id of each device allows the driver core to enumerate devices, so we don't have to do that ourselves. This changes the names of devices in sysfs from "%02x" to "zorro%u". Note that filling in dev.id is also needed to support MFD Zorro devices. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro: Refactor conditional handling of Zorro device name databaseGeert Uytterhoeven3-11/+7
Using an empty static inline function in the CONFIG_ZORRO_NAMES=n case allows to drop compilation of names.c. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro: Don't fill in dummy names in zorro_name_device()Geert Uytterhoeven1-1/+0
If the device is not found in the database, it's not needed to fill in a dummy name. The caller of zorro_name_device() has already taken care of that to support CONFIG_ZORRO_NAMES=n. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26zorro: Do not allocate zorro_autocon[] staticallyGeert Uytterhoeven4-9/+38
Currently the array of Zorro devices is allocated statically, wasting up to 4.5 KiB when running an Amiga or multi-platform kernel on a machine with no or a handful of Zorro expansion cards. Convert it to conditional dynamic memory allocation to fix this. amiga_parse_bootinfo() still needs to store some information about the detected Zorro devices, at a time even the bootmem allocator is not yet available. This is now handled using a much smaller array (typically less than 0.5 KiB), which is __initdata and thus freed later. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26Documentation/zorro.txt: Update path to arch-specific header filesGeert Uytterhoeven1-1/+1

2013-11-26m68k/sun3: Dynamically allocate the table to track IOMMU useGeert Uytterhoeven1-2/+3
As Sun 3 kernels cannot be multi-platform due to the different Sun 3 MMU type, it made sense to statically allocate the table to track IOMMU use. However, Sun 3x kernels can be multi-platform. Furthermore, Sun 3x uses a larger table than Sun 3 (8192 bytes instead of 512 bytes). Hence switch to dynamic allocation of this table using the bootmem allocator to avoid wasting 8192 bytes when not running on a Sun 3x. As this allocator returns zeroed memory, there's no need to explicitly initialize the table to zeroes. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2013-11-26m68k: Mark functions only called from setup_arch() __initGeert Uytterhoeven12-21/+22
Some functions that are only called (indirectly) from setup_arch() lack __init annotations. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
