2013-10-29MIPS: mm: Use scratch for PGD when !CONFIG_MIPS_PGD_C0_CONTEXTJayachandran C
Allow usage of scratch register for current pgd even when MIPS_PGD_C0_CONTEXT is not configured. MIPS_PGD_C0_CONTEXT is set for 64r2 platforms to indicate availability of Xcontext for saving cpuid, thus freeing Context to be used for saving PGD. This option was also tied to using a scratch register for storing PGD. This commit will allow usage of scratch register to store the current pgd if one can be allocated for the platform, even when MIPS_PGD_C0_CONTEXT is not set. The cpuid will be kept in the CP0 Context register in this case. The code to store the current pgd for the TLB miss handler is now generated in all cases. When scratch register is available, the PGD is also stored in the scratch register.

2013-10-29MIPS: Tell R4k SC and MC variations apartMaciej W. Rozycki
There is no reliable way to tell R4000/R4400 SC and MC variations apart, however simple heuristic should give good results. Only the MC version supports coherent caching so we can rely on such a mode having been set for KSEG0 by the power-on firmware to reliably indicate an MC processor. SC processors reportedly hang on coherent cached memory accesses and Linux is linked to a cached load address so the firmware has to use the correct caching mode to download the kernel image in a cached mode successfully. OTOH if the firmware chooses to use either the non-coherent cached or the uncached mode for KSEG0 on an MC processor, then the SC variant will be reported, just as we currently do, so no regression here.

2013-10-29MIPS: DECstation I/O ASIC DMA interrupt classesMaciej W. Rozycki
This change complements commits d0da7c002f7b2a93582187a9e3f73891a01d8ee4 [MIPS: DEC: Convert to new irq_chip functions] and 5359b938c088423a28c41499f183cd10824c1816 [MIPS: DECstation I/O ASIC DMA interrupt handling fix] and implements automatic handling of the two classes of DMA interrupts the I/O ASIC implements, informational and errors. Informational DMA interrupts do not stop the transfer and use the `handle_edge_irq' handler that clears the request right away so that another request may be recorded while the previous is being handled. DMA error interrupts stop the transfer and require a corrective action before DMA can be reenabled. Therefore they use the `handle_fasteoi_irq' handler that only clears the request on the way out. Because MIPS processor interrupt inputs, one of which the I/O ASIC's interrupt controller is cascaded to, are level-triggered it is recommended that error DMA interrupt action handlers are registered with the IRQF_ONESHOT flag set so that they are run with the interrupt line masked. This change removes the export of clear_ioasic_dma_irq that now does not have to be called by device drivers to clear interrupts explicitly anymore. Originally these interrupts were cleared in the .end handler of the `irq_chip' structure, before it was removed. Signed-off-by: Maciej W.

When CONFIG_SYS_SUPPORTS_ZBOOT is not enabled, we will still try to build the decompressor code in arch/mips/boot/compressed as a dependency for producing the vmlinuz target and this will result in the following build failure: OBJCOPY arch/mips/boot/compressed/vmlinux.bin arch/mips/boot/compressed/decompress.c: In function 'decompress_kernel': arch/mips/boot/compressed/decompress.c:105:2: error: implicit declaration of function 'decompress' make[1]: *** [arch/mips/boot/compressed/decompress.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [vmlinuz] Error 2 This is a genuine build failure because we have no implementation for the decompress() function body since no kernel compression method defined in CONFIG_KERNEL_(GZIP,BZIP2...) has been enabled. arch/mips/Makefile already guards the install target for the "vmlinuz" binary with a proper ifdef CONFIG_SYS_SUPPORTS_ZBOOT, we now also do the same if we attempt to do a "make vmlinuz" and show that CONFIG_SYS_SUPPORTS_ZBOOT is not enabled.

2013-10-29MIPS: Fix start of free memory when using initrdGreg Ungerer
Currently when using an initrd on a MIPS system the start of the bootmem region of memory is set to the larger of the end of the kernel bss region (_end) or the end of the initrd. In a typical memory layout where the initrd is at some address above the kernel image this means that the start of the bootmem region will be the end of the initrd. But when we are done processing/loading the initrd we have no way to reclaim the memory region it occupied, and we lose a large chunk of now otherwise empty RAM from our final running system. The bootmem code is designed to allow this initrd to be reserved (and the code in finalize_initrd() currently does this). When the initrd is finally processed/loaded its reserved memory is freed. Fix the setting of the start of the bootmem map to be the end of the kernel.

2013-10-24of/irq: Rename of_irq_map_* functions to of_irq_parse_*Grant Likely
The OF irq handling code has been overloading the term 'map' to refer to both parsing the data in the device tree and mapping it to the internal linux irq system. This is probably because the device tree does have the concept of an 'interrupt-map' function for translating interrupt references from one node to another, but 'map' is still confusing when the primary purpose of some of the functions are to parse the DT data. This patch renames all the of_irq_map_* functions to of_irq_parse_* which makes it clear that there is a difference between the parsing phase and the mapping phase. Kernel code can make use of just the parsing or just the mapping support as needed by the subsystem. The patch was generated mechanically with a handful of sed commands.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull gcc "asm goto" miscompilation workaround from Ingo Molnar: "This is the fix for the GCC miscompilation discussed in the following lkml thread: [x86] BUG: unable to handle kernel paging request at 00740060 The bug in GCC has been fixed by Jakub and the fix will be part of the GCC 4.8.2 release expected to be released next week - so the quirk's version test checks for <= 4.8.1. The quirk is only added to compiler-gcc4.h and not to the higher level compiler.h because all asm goto uses are behind a feature check" * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: compiler/gcc4: Add quirk for 'asm goto' miscompilation bug
