2011-09-28arm/imx: change mxc_init_l2x0() to an imx31/35 specific callShawn Guo3-57/+38
The mxc_init_l2x0() should really be an imx31/35 specific call. The patch removes early_initcall from mxc_init_l2x0() and get imx31 and imx35 soc specific function calls mxc_init_l2x0(), so that it's not necessarily to be called for all imx socs when we build single image for multiple imx socs. Thus the function can be renamed to imx3_init_l2x0() and put into mm-imx3.c. It also changes the return type from integer to void. From what I see, the integer was picked just to satisfy early_initcall prototype. With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code compiles even without CONFIG_CACHE_L2X0 enabled.

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.

2011-09-21ARM: fix vmlinux.lds.S discarding sectionsRussell King1-3/+12
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.

2011-09-21mach-integrator: fix VGA base regressionLinus Walleij2-2/+2
The changes introduced in commit cc22b4c18540e5e8bf55c7d124044f9317527d3c "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.

CALL scripts/checksyscalls.sh <stdin>:46:1: warning: "__IGNORE_migrate_pages" redefined In file included from <stdin>:2: arch/arm/include/asm/unistd.h:482:1: warning: this is the location of the previous definition This is caused because we define __IGNORE_migrate_pages to be 1, but in the case of nommu, it's defined to be empty. Fix this by just defining the __IGNORE_ symbols to be empty. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-09-17ARM: 7091/1: errata: D-cache line maintenance operation by MVA may not succeedWill Deacon3-0/+44
This patch implements a workaround for erratum 764369 affecting Cortex-A9 MPCore with two or more processors (all current revisions). Under certain timing circumstances, a data cache line maintenance operation by MVA targeting an Inner Shareable memory region may fail to proceed up to either the Point of Coherency or to the Point of Unification of the system. This workaround adds a DSB instruction before the relevant cache maintenance functions and sets a specific bit in the diagnostic control register of the SCU.
