[POWERPC] Use dev_set_name in pci_64.c

2008-06-09T01:32:40+00:00

During the next merge window, pci_name()'s return value will become const, so use the new dev_set_name() instead to avoid the warning (from linux-next): arch/powerpc/kernel/pci_64.c: In function 'of_create_pci_dev': arch/powerpc/kernel/pci_64.c:193: warning: passing argument 1 of 'sprintf' discards qualifiers from pointer target type Cc: Kay Sievers Cc: Greg KH Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] Fix incorrect enabling of VMX when building signal or user context

2008-06-09T01:32:36+00:00

When building a signal or a ucontext, we can incorrectly set the MSR_VEC bit of the kernel pt_regs->msr before returning to userspace if the task -ever- used VMX. This can lead to funny result if that stack used it in the past, then "lost" it (ie. it wasn't enabled after a context switch for example) and then called get_context. It can end up with VMX enabled and the registers containing values from some other task. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Add kernstart_addr to list of allowed symbols in prom_init

2008-05-23T06:15:35+00:00

Since commit "85xx: Add support for relocatable kernel (and booting at non-zero)" (37dd2badcfcec35f5e21a0926968d77a404f03c3), PHYSICAL_START is #defined as kernstart_addr if RELOCATABLE and FLATMEM is enabled. PHYSICAL_START is used in prom_init.c and so kernstart_addr needs to be added to the list of allowed symbols that prom_init.c can access.

[POWERPC] ppc: Don't run prom_init_check for arch/ppc builds

[POWERPC] Fix default cputable entries for e200 and e500 families

2008-05-12T04:20:35+00:00

Commit 76bc080ef5a34aedb63e1691f28c6b42f3468e4e ("POWERPC] Make default cputable entries reflect selected CPU family") added default entries for the e200 and e500 families, but missed a closing brace on those entries, as pointed out by David Gibson. This adds the closing braces. Signed-off-by: Paul Mackerras

[POWERPC] Remove leftover printk in isa-bridge.c

2008-05-09T10:22:59+00:00

This printk() appears twice in the same function. Only the latter one in the inval_range: section appears to be legitimate. Signed-off-by: Nate Case Acked-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Initialize lockdep earlier

2008-05-09T10:22:58+00:00

This moves lockdep_init() to before udbg_early_init() as the later can call things that acquire spinlocks etc... This also makes printk safer to use earlier. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[POWERPC] Document when printk is useable

2008-05-09T10:22:58+00:00

When debugging early boot problems, it's common to sprinkle printk's all over the place. However, on 64-bit powerpc, this can lead to memory corruption if done too early due to the PACA pointer and lockdep core not being initialized. This adds some comments to early_setup() that document when it is safe to do so in order to save time for whoever has to debug that stuff next.
