2011-06-27Fix node_start/end_pfn() definition for mm/page_cgroup.cKAMEZAWA Hiroyuki9-53/+1
commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end of nodes. But, it's not defined in linux/mmzone.h but defined in /arch/???/include/mmzone.h which is included only under CONFIG_NEED_MULTIPLE_NODES=y. Then, we see mm/page_cgroup.c: In function 'page_cgroup_init': mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn' mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn' So, fixiing page_cgroup.c is an idea... But node_start_pfn()/node_end_pfn() is a very generic macro and should be implemented in the same manner for all archs. (m32r has different implementation...) This patch removes definitions of node_start/end_pfn() in each archs and defines a unified one in linux/mmzone.h. It's not under CONFIG_NEED_MULTIPLE_NODES, now. A result of macro expansion is here (mm/page_cgroup.c) for !NUMA start_pfn = ((&contig_page_data)->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); for NUMA (x86-64) start_pfn = ((node_data[nid])->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); Changelog: - fixed to avoid using "nid" twice in node_end_pfn() macro.

2011-06-22[S390] allow setting of upper 32 bit in smp_ctl_set_bitJan Glauber1-2/+2
The bit shift operation in smp_ctl_set_bit does not specify the type of the shifted bit so integer is used as default. Therefore it is not possible to set bits in the upper 32 bit of the control register if the kernel runs in 64 bit mode. Fix this by specifying the type as unsigned long.

2011-06-22[S390] hwsampler: Set a sane default sampling rateChristian Borntraeger1-1/+1
The sampling interval for the hardware sampler is specified in cycles. (see SA23-2260-01 The Load-Program-Parameter and the CPU-Measurement Facilities) The current default value will therefore result in millions of samples. This patch changes the default sampling interval to 4M, which will result in ~1500 samples per second on a z196 reducing the overhead of sampling.

2011-06-22powerpc/e500: fix breakage with fsl_rio_mcheck_exceptionScott Wood2-18/+19
The wrong MCSR bit was being used on e500mc. MCSR_BUS_RBERR only exists on e500v1/v2. Use MCSR_LD on e500mc, and remove all MCSR checking in fsl_rio_mcheck_exception as we now no longer call that function if the appropriate bit in MCSR is not set. If RIO support was enabled at compile-time, but was never probed, just return from fsl_rio_mcheck_exception rather than dereference a NULL pointer. TODO: There is still a remaining, though comparitively minor, issue in that this recovery mechanism will falsely engage if there's an unrelated MCSR_LD event at the same time as a RIO error.

2011-06-22powerpc/p1022ds: fix audio-related properties in the device treeTimur Tabi1-3/+6
On the Freescale P1022DS reference board, the SSI audio controller is connected in "asynchronous" mode to the codec's clocks, so the device tree needs an "fsl,ssi-asynchronous" property. Also remove the clock-frequency property from the wm8776 node, because the clock is enabled only if U-Boot enables it, and U-Boot will set the property if the clock is enabled. A future version of the P1022DS audio driver will configure the clock itself, but for now, the driver should not be told that the clock is running when it isn't. Also fix the FIFO depth to 15, instead of 16. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-06-21net: remove mm.h inclusion from netdevice.hAlexey Dobriyan17-0/+17
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-06-19KVM: MMU: Fix build warnings in walk_addr_generic()Borislav Petkov1-1/+1
On 3.0-rc1 I get In file included from arch/x86/kvm/mmu.c:2856: arch/x86/kvm/paging_tmpl.h: In function ‘paging32_walk_addr_generic’: arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function In file included from arch/x86/kvm/mmu.c:2852: arch/x86/kvm/paging_tmpl.h: In function ‘paging64_walk_addr_generic’: arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function caused by 6e2ca7d1802bf8ed9908435e34daa116662e7790. According to Takuya Yoshikawa, ptep_user won't be used uninitialized so shut up gcc.

2011-06-18x86, efi: Do not reserve boot services regions within reserved areasMaarten Lankhorst3-7/+28
Commit 916f676f8dc started reserving boot service code since some systems require you to keep that code around until SetVirtualAddressMap is called. However, in some cases those areas will overlap with reserved regions. The proper medium-term fix is to fix the bootloader to prevent the conflicts from occurring by moving the kernel to a better position, but the kernel should check for this possibility, and only reserve regions which can be reserved.
