2011-05-20extable, core_kernel_data(): Make sure all archs define _sdataSteven Rostedt
A new utility function (core_kernel_data()) is used to determine if a passed in address is part of core kernel data or not. It may or may not return true for RO data, but this utility must work for RW data. Thus both _sdata and _edata must be defined and continuous, without .init sections that may later be freed and replaced by volatile memory (memory that can be freed). This utility function is used to determine if data is safe from ever being freed. Thus it should return true for all RW global data that is not in a module or has been allocated, or false otherwise. Also change core_kernel_data() back to the more precise _sdata condition and document the function.

2011-05-19m68k: bitops - Never step beyond the end of the bitmapGeert Uytterhoeven
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and find_next_bit_le) may cause out of bounds memory access when the bitmap size in bits % 32 != 0 and offset (the bitnumber to start searching at) is very close to the bitmap size. For example, unsigned long bitmap[2] = { 0, 0 }; find_next_bit(bitmap, 63, 62); 1. find_next_bit() tries to find any set bits in bitmap[1], but no bits set. 2. Then find_first_bit(bimap + 2, -1) 3. Unfortunately find_first_bit() takes unsigned int as the size argument. 4. find_first_bit will access bitmap[2~] until it find any set bits. Add missing tests for stepping beyond the end of the bitmap to all find_{first,next}_*() functions, and make sure they never return a value larger than the bitmap size.

2011-04-27m68k/mm: Set all online nodes in N_NORMAL_MEMORYMichael Schmitz
For m68k, N_NORMAL_MEMORY represents all nodes that have present memory since it does not support HIGHMEM. This patch sets the bit at the time node_present_pages has been set by free_area_init_node. At the time the node is brought online, the node state would have to be done unconditionally since information about present memory has not yet been recorded. If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it uses this nodemask to setup per-cache kmem_cache_node data structures. This pach is an alternative to the one proposed by David Rientjes <rientjes@google.com> attempting to set node state immediately when bringing the node online.

2011-03-25m68k: merge m68k and m68knommu arch directoriesGreg Ungerer
There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2011-03-23bitops: remove minix bitops from asm/bitops.hAkinobu Mita
minix bit operations are only used by minix filesystem and useless by other modules. Because byte order of inode and block bitmaps is different on each architecture like below: m68k: big-endian 16bit indexed bitmaps h8300, microblaze, s390, sparc, m68knommu: big-endian 32 or 64bit indexed bitmaps m32r, mips, sh, xtensa: big-endian 32 or 64bit indexed bitmaps for big-endian mode little-endian bitmaps for little-endian mode Others: little-endian bitmaps In order to move minix bit operations from asm/bitops.h to architecture independent code in minix filesystem, this provides two config options. CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k. CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu, m32r, mips, sh, xtensa). The architectures which always use little-endian bitmaps do not select these options. Finally, we can remove minix bit operations from asm/bitops.h for all architectures.

2011-03-15m68knommu: external interrupt support to ColdFire intc-simr controllerGreg Ungerer
The EDGE Port module of some ColdFire parts using the intc-simr interrupt controller provides support for 7 external interrupts. These interrupts go off-chip (that is they are not for internal peripherals). They need some special handling and have some extra setup registers. Add code to support them.

2011-03-15m68knommu: remove ColdFire CLOCK_DIV config optionGreg Ungerer
The reality is that you do not need the abiltity to configure the clock divider for ColdFire CPUs. It is a fixed ratio on any given ColdFire family member. It is not the same for all ColdFire parts, but it is always the same in a model range. So hard define the divider for each supported ColdFire CPU type and remove the Kconfig option.

2011-03-15m68knommu: make ColdFire internal peripheral region configurableGreg Ungerer
Most ColdFire CPUs have an internal peripheral set that can be mapped at a user selectable address. Different ColdFire parts either use an MBAR register of an IPSBAR register to map the peripheral region. Most boards use the Freescale default mappings - but not all. Make the setting of the MBAR or IPSBAR register configurable. And only make the selection available on the appropriate ColdFire CPU types. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-03-15m68knommu: clean up definitions of ColdFire peripheral base registersGreg Ungerer
Different ColdFire CPUs have different ways of defining where their internal peripheral registers sit in their address space. Some use an MBAR register, some use and IPSBAR register, some have a fixed mapping. Now that most of the peripheral address definitions have been cleaned up we can clean up the setting of the MBAR and IPSBAR defines to limit them to just where they are needed (and where they actually exist).

2011-03-15m68knommu: clean up use of MBAR for DRAM registers on ColdFire startGreg Ungerer
In some of the RAM size autodetection code on ColdFire CPU startup we reference DRAM registers relative to the MBAR register. Not all of the supported ColdFire CPUs have an MBAR, and currently this works because we fake an MBAR address on those registers. In an effort to clean this up, and eventually remove the fake MBAR setting make the DRAM register address definitions actually contain the MBAR (or IPSBAR as appropriate) value as required.

2011-03-15m68knommu: remove use of MBAR in old-style ColdFire timerGreg Ungerer
Not all ColdFire CPUs that use the old style timer hardware module use an MBAR set peripheral region. Move the TIMER base address defines to the per-CPU header files where we can set it correctly based on how the peripherals are mapped - instead of using a fake MBAR for some platforms.

2011-03-15m68knommu: move ColdFire DMA register addresses to per-cpu headersGreg Ungerer
The base addresses of the ColdFire DMA unit registers belong with all the other address definitions in the per-cpu headers. The current definitions assume they are relative to an MBAR register. Not all ColdFire CPUs have an MBAR register. A clean address define can only be acheived in the per-cpu headers along with all the other chips peripheral base addresses.
