2008-12-29powerpc/44x: Support 16K/64K base page sizes on 44xIlya Yanok10-48/+130
This adds support for 16k and 64k page sizes on PowerPC 44x processors. The PGDIR table is much smaller than a page when using 16k or 64k pages (512 and 32 bytes respectively) so we allocate the PGDIR with kzalloc() instead of __get_free_pages(). One PTE table covers rather a large memory area when using 16k or 64k pages (32MB or 512MB respectively), so we can easily put FIXMAP and PKMAP in the area covered by one PTE table.

2008-12-29powerpc: Force memory size to be a multiple of PAGE_SIZEHollis Blanchard1-1/+15
Ensure that total memory size is page-aligned, because otherwise mark_bootmem() gets upset. This error case was triggered by using 64 KiB pages in the kernel while arch/powerpc/boot/4xx.c arbitrarily reduced the amount of memory by 4096 (to work around a chip bug that affects the last 256 bytes of physical memory).

2008-12-28m68k: mac baboon interrupt enable/disableFinn Thain2-15/+35
No-one seems to know how to mask individual baboon interrupts, so we just mask the umbrella IRQ. This will work as long as only the IDE driver uses the baboon chip (it can't deadlock). Use mac_enable_irq/mac_disable_irq rather than enable_irq/disable_irq because the latter routines count the depth of nested calls which triggers a warning and call trace because IRQ_NUBUS_C is enabled twice in a row (once when the baboon handler is registered, and once when the IDE IRQ is registered).

2008-12-25[S390] remove ptrace warning on 31 bit.Martin Schwidefsky1-6/+4
A kernel compile on 31 bit gives the following warnings in ptrace.c: arch/s390/kernel/ptrace.c: In function 'peek_user': arch/s390/kernel/ptrace.c:207: warning: unused variable 'dummy' arch/s390/kernel/ptrace.c: In function 'poke_user': arch/s390/kernel/ptrace.c:315: warning: unused variable 'dummy' Getting rid of the dummy variables removes the warnings.

2008-12-25[S390] service level interface.Martin Schwidefsky1-0/+11
Add a new proc interface /proc/service_levels that allows any code to report a relevant service level, e.g. the microcode level of devices, the service level of the hypervisor, etc. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-12-25[S390] qdio: rework debug feature loggingJan Glauber1-10/+0
- make qdio_trace a per device view - remove s390dbf exceptions - remove CONFIG_QDIO_DEBUG, not needed anymore if we check for the level before calling sprintf - use snprintf for dbf entries - add start markers to see if the dbf view wrapped - add a global error view for all queues Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-12-25[S390] qdio: fix qeth port count detectionJan Glauber1-8/+8
qeth needs to get the port count information before qdio has allocated a page for the chsc operation. Extend qdio_get_ssqd_desc() to store the data in the specified structure. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
