The SMP implementation of __futex_atomic_op clobbers oldval with the status flag from the exclusive store. This causes it to always read as zero when performing the FUTEX_OP_CMP_* operation. This patch updates the ARM __futex_atomic_op implementations to take a tmp argument, allowing us to store the strex status flag without overwriting the register containing oldval.

We are seeing linker errors caused by sections being discarded, despite the linker script trying to keep them. The result is (eg): `.exit.text' referenced in section `.alt.smp.init' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o `.exit.text' referenced in section `.alt.smp.init' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o This is the relevent part of the linker script (reformatted to make it clearer): | SECTIONS | { | /* | * unwind exit sections must be discarded before the rest of the | * unwind sections get included. | */ | /DISCARD/ : { | *(.ARM.exidx.exit.text) | *(.ARM.extab.exit.text) | } | ... | .exit.text : { | *(.exit.text) | *(.memexit.text) | } | ... | /DISCARD/ : { | *(.exit.text) | *(.memexit.text) | *(.exit.data) | *(.memexit.data) | *(.memexit.rodata) | *(.exitcall.exit) | *(.discard) | *(.discard.*) | } | } Now, this is what the linker manual says about discarded output sections: | The special output section name `/DISCARD/' may be used to discard | input sections. Any input sections which are assigned to an output | section named `/DISCARD/' are not included in the output file. No questions, no exceptions. It doesn't say "unless they are listed before the /DISCARD/ section." Now, this is what asn-generic/vmlinux.lds.S says: | /* | * Default discarded sections. | * | * Some archs want to discard exit text/data at runtime rather than | * link time due to cross-section references such as alt instructions, | * bug table, eh_frame, etc. DISCARDS must be the last of output | * section definitions so that such archs put those in earlier section | * definitions. | */ And guess what - the list _always_ includes .exit.text etc. Now, what's actually happening is that the linker is reading the script, and it finds the first /DISCARD/ output section at the beginning of the script. It continues reading the script, and finds the 'DISCARD' macro at the end, which having been postprocessed results in another /DISCARD/ output section. As the linker already contains the earlier /DISCARD/ output section, it adds it to that existing section, so it effectively is placed at the start. This can be seen by using the -M option to ld: | Linker script and memory map | | 0xc037c080 jiffies = jiffies_64 | | /DISCARD/ | *(.ARM.exidx.exit.text) | *(.ARM.extab.exit.text) | *(.exit.text) | *(.memexit.text) | *(.exit.data) | *(.memexit.data) | *(.memexit.rodata) | *(.exitcall.exit) | *(.discard) | *(.discard.*) | | 0xc0008000 . = 0xc0008000 | | .head.text 0xc0008000 0x1d0 | 0xc0008000 _text = . | *(.head.text) | .head.text 0xc0008000 0x1d0 arch/arm/kernel/head.o | 0xc0008000 stext | | .text 0xc0008200 0x2d78d0 | 0xc0008200 _stext = . | 0xc0008200 __exception_text_start = . | *(.exception.text) | .exception.text | ... As you can see, all the discarded sections are grouped together - and as a result of it being the first output section, they all appear before any other section. The result is that not only is the unwind information discarded (as intended), but also the .exit.text, despite us wanting to have the .exit.text preserved. We can't move the unwind information elsewhere, because it'll then be included even when we do actually discard the .exit.text (and similar) sections. So, work around this by avoiding the generic DISCARDS macro, and instead conditionalize the sections to be discarded ourselves. This avoids the ambiguity in how the linker assigns input sections to output sections, making our script less dependent on undocumented linker behaviour.

The changes introduced in commit cc22b4c1 "ARM: set vga memory base at run-time" Makes the Integrator/AP freeze completely. I appears that this is due to the VGA base address being assigned at PCI init time, while this base is needed earlier than that. Moving the initialization of the base address to the .map_io function solves this problem.

DA850/OMAP-L138 EMAC driver uses random mac address instead of a fixed one because the mac address is not stuffed into EMAC platform data. This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.

This patch removes support for the SGX interrupt source in the sh7372 INTCS controller. The SGX hardware block included in sh7372 is already hooked up to the ARM Cortex-A8 core using the INTCA controller, so SGX users are encouraged to make use of that interrupt source instead. Removing support for the SGX interrupt source in INTCS simplifies the sh7372 power management code by allowing us to assume that only INTCA needs to be powered on to operate the SGX hardware. If the INTCS interrupt source would be kept then the kernel would be forced to deal with additional dependencies that does not follow the regular power domain hiearachy. With this patch in place we can safely power down INTCS while the SGX is operating. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
