Pull MIPS fixes from Ralf Baechle: "This is the final pull request for MIPS for 4.4. It fixes: - scripts/ld-version.sh parsing of ld version numbers that contain large numbers as components. - fix parsing of version numbers as used by Fedora's ld.

2016-01-06net: filter: make JITs zero A for SKF_AD_ALU_XOR_XRabin Vincent
The SKF_AD_ALU_XOR_X ancillary is not like the other ancillary data instructions since it XORs A with X while all the others replace A with some loaded value. All the BPF JITs fail to clear A if this is used as the first instruction in a filter. This was found using american fuzzy lop. Add a helper to determine if A needs to be cleared given the first instruction in a filter, and use this in the JITs. Except for ARM, the rest have only been compile-tested.

2016-01-04Fix ld-version.sh to handle large 3rd version partJames Hogan
The ld-version.sh script doesn't handle versions with large (>= 10) 3rd version components, because the 2nd component is only multiplied by 10 times that of the 3rd component. For example the following version string: GNU ld (Codescape GNU Tools 2015.06-05 for MIPS MTI Linux) 2.24.90 gives a bogus version number: 20000000 + 2400000 + 900000 = 23300000 Breakage, confusion and mole-whacking ensues. Increase the multipliers of the first two version components by a factor of 10 to give space for a 3rd components of up to 99, and update the sole user of ld-ifversion (MIPS VDSO) accordingly.

2015-12-22MIPS: CPS: drop .set mips64r2 directivesPaul Burton
Commit 977e043d5ea1 ("MIPS: kernel: cps-vec: Replace mips32r2 ISA level with mips64r2") leads to .set mips64r2 directives being present in 32 bit (ie. CONFIG_32BIT=y) kernels. This is incorrect & leads to MIPS64 instructions being emitted by the assembler when expanding pseudo-instructions. For example the "move" instruction can legitimately be expanded to a "daddu". This causes problems when the kernel is run on a MIPS32 CPU, as CONFIG_32BIT kernels of course often are... Fix this by dropping the .set <ISA> directives entirely now that Kconfig should be ensuring that kernels including this code are built with a suitable -march= compiler flag.

2015-12-22MIPS: uaccess: Take EVA into account in [__]clear_userJames Hogan
__clear_user() (and clear_user() which uses it), always access the user mode address space, which results in EVA store instructions when EVA is enabled even if the current user address limit is KERNEL_DS. Fix this by adding a new symbol __bzero_kernel for the normal kernel address space bzero in EVA mode, and call that from __clear_user() if eva_kernel_access().

2015-12-22MIPS: uaccess: Take EVA into account in __copy_from_user()James Hogan
When EVA is in use, __copy_from_user() was unconditionally using the EVA instructions to read the user address space, however this can also be used for kernel access. If the address isn't a valid user address it will cause an address error or TLB exception, and if it is then user memory may be read instead of kernel memory. For example in the following stack trace from Linux v3.10 (changes since then will prevent this particular one still happening) kernel_sendmsg() set the user address limit to KERNEL_DS, and tcp_sendmsg() goes on to use __copy_from_user() with a kernel address in KSeg0.

2015-12-22MIPS: uaccess: Fix strlen_user with EVAJames Hogan
The strlen_user() function calls __strlen_kernel_asm in both branches of the eva_kernel_access() conditional. For EVA it should be calling __strlen_user_eva for user accesses, otherwise it will load from the kernel address space instead of the user address space, and the access checking will likely be ineffective at preventing it due to EVA's overlapping user and kernel address spaces. This was found after extending the test_user_copy module to cover user string access functions, which gave the following error with EVA: test_user_copy: illegal strlen_user passed Fortunately the use of strlen_user() has been all but eradicated from the mainline kernel, so only out of tree modules could be affected.

2015-12-12MIPS: fix DMA contiguous allocationQais Yousef
Recent changes to how GFP_ATOMIC is defined seems to have broken the condition to use mips_alloc_from_contiguous() in mips_dma_alloc_coherent(). I couldn't bottom out the exact change but I think it's this commit d0164adc89f6 ("mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd"). GFP_ATOMIC has multiple bits set and the check for !(gfp & GFP_ATOMIC) isn't enough. The reason behind this condition is to check whether we can potentially do a sleeping memory allocation. Use gfpflags_allow_blocking() instead which should be more robust.

2015-11-16regmap-mmio: Use native endianness for read/writeSimon Arlott
The regmap API has an endianness setting for formatting reads and writes. This can be set by the usual DT "little-endian" and "big-endian" properties. To work properly the associated regmap_bus needs to read/write in native endian. The "syscon" DT device binding creates an mmio-based regmap_bus which performs all reads/writes as little-endian. These values are then converted again by regmap, which means that all of the MIPS BCM boards (which are big-endian) have been declared as "little-endian" to get regmap to convert them back to big-endian. Modify regmap-mmio to use the native-endian functions __raw_read*() and __raw_write*() instead of the little-endian functions read*() and write*(). Modify the big-endian MIPS BCM boards to use what will now be the correct endianness instead of pretending that the devices are little-endian.

2015-11-12MIPS: Clean up compat_siginfo_tAmanieu d'Antras
While mips can't use the generic compat_siginfo_t directly because its si_code and si_errno are inverted, we can still make it as close to the generic version as possible. This makes it easier to update when new members are added to siginfo_t. The main changes are adding a missing _sigsys union member and eliminating the unused _irix_sigchld one.

2015-11-11MIPS: Make MIPS_CMDLINE_DTB defaultJonas Gorski
Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied the arguments from dtb to arcs_command_line to prevent the kernel from overwriting them. Since there is now an option to keep the dtb arguments, default to the new option remove the "backup" to arcs_command_line in case of USE_OF is enabled, except for those platforms that still take the bootloader arguments or do not use any at all.

2015-11-11MIPS: Make the kernel arguments from dtb availableJonas Gorski
Similar to how arm allows using selecting between bootloader arguments, dtb arguments and both, allow to select them on mips. But since we have less control over the place of the dtb do not modify it but instead use the boot_command_line for merging them. The default is "use bootloader arguments" to keep the current behaviour as default.
