      m68k: print memory layout info in boot log · e87c09a8
      Greg Ungerer 提交于
      Output a table of the kernel memory regions at boot time.
      This is taken directly from the ARM architecture code that does this.
      The table looks like this:
      
      Virtual kernel memory layout:
          vector  : 0x00000000 - 0x00000400   (   0 KiB)
          kmap    : 0xd0000000 - 0xe0000000   ( 256 MiB)
          vmalloc : 0xc0000000 - 0xcfffffff   ( 255 MiB)
          lowmem  : 0x00000000 - 0x02000000   (  32 MiB)
            .init : 0x00128000 - 0x00134000   (  48 KiB)
            .text : 0x00020000 - 0x00118d54   ( 996 KiB)
            .data : 0x00118d60 - 0x00126000   (  53 KiB)
            .bss  : 0x00134000 - 0x001413e0   (  53 KiB)
      
      This has been very useful while debugging the ColdFire virtual memory
      support code. But in general I think it is nice to know extacly where
      the kernel has layed everything out on boot.

      m68knommu: correctly use trap_init · 622e9472
      Greg Ungerer 提交于
      Currently trap_init() is an empty function for m68knommu. Instead
      the vectors are being setup as part of the IRQ initialization.
      This is inconsistent with m68k and other architectures.
      
      Change the local init_vectors() to be trap_init(), and init the
      vectors at the correct time during startup. This will help merge of
      m68k and m68knommu trap code in the furture.

      m68k,m68knommu: merge header files · 49148020
      Sam Ravnborg 提交于
      Merge header files for m68k and m68knommu to the single location:
      
          arch/m68k/include/asm
      
      The majority of this patch was the result of the
      script that is included in the changelog below.
      
      The script was originally written by Arnd Bergman and
      exten by me to cover a few more files.
      
      When the header files differed the script uses the following:
      
      The original m68k file is named <file>_mm.h  [mm for memory manager]
      The m68knommu file is named <file>_no.h [no for no memory manager]
      
      The files uses the following include guard:
      
      This include gaurd works as the m68knommu toolchain set
      the __uClinux__ symbol - so this should work in userspace too.
      
      Merging the header files for m68k and m68knommu exposes the
      (unexpected?) ABI differences thus it is easier to actually
      identify these and thus to fix them.
      
      The commit has been build tested with both a m68k and
      a m68knommu toolchain - with success.
      
      The commit has also been tested with "make headers_check"
      and this patch fixes make headers_check for m68knommu.
