Hi all,

After merging the fsl tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

Thanks for letting me know. I have dropped this patch for now.

CONFIG_USB_FHCI_HCD depends on CONFIG_QE_GPIO but uses in_be16() etc ... 
helpers which are powerpc specific, so dependency to PPC needs to be 
kept for now.

linux-next: build failure after merge of the fsl tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 466 bytes --]

Hi Scott,

After merging the fsl tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/kernel/built-in.o: In function `.dma_direct_alloc_coherent':
(.text+0x14bc8): undefined reference to `.dma_pfn_limit_to_zone'

Probably caused by commit 1c98025c6c95 ("powerpc: Dynamic DMA zone
limits").

I have used the fsl tree from next-20140917 for today.

linux-next: build failure after merge of the fsl tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 572 bytes --]

Hi Scott,

After merging the fsl tree, today's linux-next build (powerpc
allyesconfig) failed like this:

arch/powerpc/kernel/epapr_paravirt.c: In function 'epapr_idle_init':
arch/powerpc/kernel/epapr_paravirt.c:77:23: error: 'epapr_ev_idle' undeclared (first use in this function)
   ppc_md.power_save = epapr_ev_idle;
                       ^

Caused by commit 7762b1ed7aae ("powerpc: move epapr paravirt init of
power_save to an initcall").

I have reverted that commit for today.
