The problem is # that during the conversion from a byte array to a time64_t, the # 'unsigned char' variable holding the top byte gets turned into a # negative signed 32-bit integer before being assigned to the 64-bit # variable for any times after 1972. # # This changes the logic to cast to an unsigned 32-bit number first for # the Macintosh time and then convert that to the Unix time, which then # gives us a time in the documented 1904..2040 year range. I decided not # to use the longer 1970..2106 range that other drivers use, for # consistency with the literal interpretation of the register, but that # could be easily changed if we decide we want to support any Mac after # 2040. # # Just to be on the safe side, I'm also adding a WARN_ON that will # trigger if either the year 2040 has come and is observed by this # driver, or we run into an RTC that got set back to a pre-1970 date for # some reason (the two are indistinguishable). # # For the RTC write functions, Andreas found another problem: both # pmu_request() and cuda_request() are varargs functions, so changing # the type of the arguments passed into them from 32 bit to 64 bit # breaks the API for the set_rtc_time functions. This changes it back to # 32 bits. # # The same code exists in arch/m68k/ and is patched in an identical way # now in a separate patch. # # Fixes: 5bfd643583b2 ("powerpc: use time64_t in read_persistent_clock") # Reported-by: Mathieu Malaterre <malat@debian.org> # Reported-by: Andreas Schwab <schwab@linux-m68k.org> # Signed-off-by: Arnd Bergmann <arnd@arndb.de> # Tested-by: Mathieu Malaterre <malat@debian.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < git log --format=%s --max-count=1 22db552b50fa11d8c1d171de908a1f9ef62172b7 # < make -s -j 48 ARCH=sh O=/kisskb/build/powerpc-fixes_sh-defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- defconfig # make -s -j 48 ARCH=sh O=/kisskb/build/powerpc-fixes_sh-defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
