2008-07-15[MIPS] i8253: make the pit_clockevent variable staticDmitri Vorobiev
The pit_clockevent symbol is needlessly defined global. This patch makes that variable static. Spotted by sparse. Compile-tested using Malta defconfig. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.fi> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-07-15[MIPS] Enable FAST-20 for onboard scsiThomas Bogendoerfer
Both onboard controller of the O2 support FAST-20 transfer speeds, but the bit, which signals that to the aic driver, isn't set. Instead of adding detection code to the scsi driver, we just fake the missing bit in the PCI config space of the scsi chips.

2008-07-15[MIPS] unexport {allocate,free}_irqnoDmitri Vorobiev
The following routines allocate_irqno() free_irqno() seem not to be used outside of the core kernel code, hence exporting these functions is pointless. This patch removes the export. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.fi> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-07-15[MIPS] Make two functions staticDmitri Vorobiev
The following routines uasm_rel_highest() uasm_rel_higher() are needlessly defined global. This patch makes them static. Compile-tested using a customized config for the Malta board. Booting the same board up to the shell prompt was also successful with this patch applied. Spotted by sparse.

2008-07-15[MIPS] fix sparse warning about setup_early_printk()Dmitri Vorobiev
This patch fixes the following sparse warning: <<<<<<<< arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk' was not declared. Should it be static? <<<<<<<< The fix is to define a prototype of the setup_early_printk() function and to include the appropriate header into arch/mips/kernel/early_printk.c.

2008-07-14[S390] arch/s390: Eliminate NULL test and memset after alloc_bootmemJulia Lawall
As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary. arch/s390/kernel/topology.c | 2 -- 1 file changed, 2 deletions(-) This was fixed using the following semantic patch.

2008-07-14[S390] initrd vs bss section clearing.Heiko Carstens
In case the initrd is located within the bss section it will be overwritten when the section is cleared. To prevent this just move the initrd right behind the bss section if it starts within the section. The current code already moves the initrd if the bootmem allocator bitmap would overwrite it. With this patch we should be safe against initrd corruptions.

2008-07-13x86: change _node_to_cpumask_ptr to return const ptrMike Travis
