Based upon a report by Daniel Smolik. We do it too early, which triggers a BUG in cpufreq_register_notifier(). Signed-off-by:David S. Miller <davem@davemloft.net>

We're calling request_irq() with a IRQs disabled. No straightforward fix exists because we want to enable these IRQs and setup state atomically before getting into the IRQ handler the first time. What happens now is that we mark the VIRQ to not be automatically enabled by request_irq(). Then we make explicit enable_irq() calls when we grab the LDC channel. This way we don't need to call request_irq() illegally under the LDC channel lock any more. Bump LDC version and release date. Signed-off-by:

Adrian Bunk reported that enabling 4MB page size breaks the build. The problem is that MAX_ORDER combined with the page shift exceeds the SECTION_SIZE_BITS we use in asm-sparc64/sparsemem.h There are several ways I suppose we could work around this. For one we could define a CONFIG_FORCE_MAX_ZONEORDER to decrease MAX_ORDER in these higher page size cases. But I also know that these page size cases are broken wrt. TLB miss handling especially on pre-hypervisor systems, and there isn't an easy way to fix that. These options were meant to be fun experimental hacks anyways, and only 8K and 64K make any sense to support. So remove 512K and 4M base page size support. Of course, we still support these page sizes for huge pages. Signed-off-by: -

With this commit all sparc64 header files are moved to asm-sparc. The remaining files (71 files) were too different to be trivially merged so divide them up in a _32.h and a _64.h file which are both included from the file with no bit size. The following script were used: cd include FILES=`wc -l asm-sparc64/*h | grep -v '^ 1' | cut -b 20-` for FILE in ${FILES}; do echo $FILE: BASE=`echo $FILE | cut -d '.' -f 1` FN32=${BASE}_32.h FN64=${BASE}_64.h GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H git mv asm-sparc/$FILE asm-sparc/$FN32 git mv asm-sparc64/$FILE asm-sparc/$FN64 echo git mv done printf "#ifndef %s\n" $GUARD > asm-sparc/$FILE printf "#define %s\n" $GUARD >> asm-sparc/$FILE printf "#if defined(__sparc__) && defined(__arch64__)\n" >> asm-sparc/$FILE printf "#include <asm-sparc/%s>\n" $FN64 >> asm-sparc/$FILE printf "#else\n" >> asm-sparc/$FILE printf "#include <asm-sparc/%s>\n" $FN32 >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE git add asm-sparc/$FILE echo new file done printf "#include <asm-sparc/%s>\n" $FILE > asm-sparc64/$FILE git add asm-sparc64/$FILE echo sparc64 file done done The guard contains three '_' to avoid conflict with existing guards. In additing the two Kbuild files are emptied to avoid breaking headers_* targets. We will reintroduce the exported header files when the necessary kbuild changes are merged.

A manual inspection revealed that the following headerfiles contained only trivial differences: hw_irq.h idprom.h kmap_types.h kvm.h spinlock_types.h sunbpp.h unaligned.h The only noteworthy change are that sparc64 had a volatile qualifer that sparc missed in spinlock_types.h. In addition a few comments were updated. Signed-off-by: -

Used the following script to find equal header files: SPARC64=`ls asm-sparc64` for FILE in ${SPARC64}; do cmp -s asm-sparc/$FILE asm-sparc64/$FILE; if [ $? = 0 ]; then printf "#include <asm-sparc/%s>\n" $FILE > asm-sparc64/$FILE fi done A few of the equal files are a simple include from asm-generic, but by including the file from asm-sparc we know they are equal for sparc and sparc64.

sparc64 exports openprom.h to userspace so let sparc follow the example. As openprom.h pulled in another not-for-export vaddrs.h header file it required a few changes to fix the build. The definition af VMALLOC_* were moved to pgtable as this is where sparc64 has them. Signed-off-by: -
