* m68k: Do not set global share for non-kernel shared pagesAlexander Stein2012-02-071-4/+5
| | | | | | | | | | If the SG bit is set in MMUTR the page is accessible for all userspace processes (ignoring the ASID). So a process might randomly access a page from a different process which had a shared page (from shared memory) in its context.

* m68k: Add shared bit to Coldfire kernel page entriesAlexander Stein2012-02-071-1/+2
| | | | | | | | | | | | | | | | We had problems accessing our NOR flash trough mtd. The system always got stuck at attaching UBI using ubiattach if booted from NFS or after mounting squashfs as rootfs directly from NOR flash. After some testing of the new changes introduced from v3.2-rc1 to v3.2-rc7 we had to apply the following patch to get mtd working again. [gerg: The problem was ultimately caused by allocated kernel pages not having the shared (SG) bit set. Without the SG bit set the MMU will look for page matches incorporating the ASID as well. Things like module regions allocated using vmalloc would fault when other processes run. ] Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: fix syscall tracing stuck processGreg Ungerer2012-02-071-3/+1
| | | | | | | | | | | The return path from an exception was checking too many bits in the thread_info->flags, and getting stuck calling do_signal(). There was no work to do, we should only be checking the low 8 bits (as per comments and definitions in arch/m68k/include/asm/thread_info.h). This fixes the stuck process problem when using strace.

| | | | | | | | | | | | | | | | | | | | Passing the address of a variable as an operand to an asm statement doesn't mark the value of this variable as used, so gcc may optimize its initialisation away.

This undesirable coupling between drivers only exists because the OSS driver doesn't correctly handle all of its machspec IRQs. Fix OSS handling of enable/disable for VIA1 IRQs (8 thru 15) which includes MAC_IRQ_ADB. Back when I implemented pmac_zilog support I redefined IRQ_MAC_SCC incorrectly. Change this to a machspec IRQ so that it works on OSS. Clean up the unused OSS audio IRQ and OSS_IRQLEV_* cruft that only confuses things. Fix the OSS description in macints.c and remove an obsolete comment. Don't enable the VIA1 irq before registering the handler.

And the consensus seems to be that the Mac TV is essentially a Performa 550, not dissimilar to the Performa 520, so set the via_type accordingly.

To avoid such hybrid kernels, introduce CONFIG_M68KCLASSIC as an antipole for CONFIG_COLDFIRE, and make all specific processor support depend on one of them. All classic m68k machine support also needs to depend on this. The defaults (CONFIG_M68KCLASSIC if MMU, CONFIG_COLDFIRE if !MMU) are chosen such to make most of the existing configs build and work.

So add code to support this hardware along side the existing m68k FPU code. The ColdFire FPU is of course different to all previous 68k FP units. It is close in operation to the 68060, but not completely compatible. The biggest issue to deal with is that the ColdFire FPU multi-move instructions are different. It does not support multi-moving the FP control registers, and the multi-move of the FP data registers uses a different instruction mnemonic.
