These headers will typically define various constants that are part of the device tree bindings. The original patch which set up the dtc+cpp include path only considered using those headers from device tree files. However, most are also useful for kernel code which needs to interpret the device tree. In both the DT files and the kernel, I'd like to include the DT-related headers in the same way, for example, . That will simplify any text which discusses the DT header locations. Creating a for kernel source to use is as simple as placing files into include/dt-bindings/. However, when compiling DT files, the include path should be restricted so that only the dt-bindings path is available; arbitrary kernel headers shouldn't be exposed. For this reason, create a specific include directory for use by dtc+cpp, and symlink dt-bindings from there to the actual location of include/dt-bindings/. For want of a better location, place this "include chroot" into the existing dts/ directory. arch/*/boot/dts/include/dt-bindings -> ../../../../../include/dt-bindings Some headers used by device tree files may not be useful to the kernel; they may be used simply to aid in constructing the DT file (e.g. macros to create a node), but not define any information that the kernel needs to share. These may be placed directly into arch/*/boot/dts/ along with the DT files themselves.

In order to transparently run the C pre-processor on device-tree files, we wish to run both gcc -E and dtc on a source file in a single rule. This generates two dependency files, which must be transformed together into the file used by the kernel build process. This change modifies fixdep so it can process the concatenation of multiple separate input dependency files, and produce a correct unified output. The code changes have the slight benefit of transforming the loop in parse_dep_file() into more of a lexer/tokenizer, with the loop body being more of a parser. Previously, some of this logic was mixed together before the loop. I also added some comments, which I hope are useful. Benchmarking shows that on a cross-compiled ARM tegra_defconfig build, there is less than 0.5 seconds speed decrease with this change, on top of a build time of ~2m24s. This is probably within the noise.

With this change, when compiling *.dtsp to *.dtb, the dependency files from both gcc -E and dtc are used. This will allow cmd_dtc_cpp to replace cmd_dtc in a future change. In turn, that will allow the C pre- processor to be run transparently on *.dts, without the need to a separate rule or file extension to trigger it.

It creates an array of new source config files and when the one file is finished, it continues with the next file. Unfortunately, this means that it loses the fact that the source file is within an "if" statement, and this means that each of these source file's configs will not have the proper dependencies set. As ATH9K requires ATH_CARDS set, the localmodconfig did not see that dependency, and did not enable ATH_CARDS. When the oldconfig was run, it forced ATH9K to be disabled.

This causes that same instruction to be tagged twice, see example below. What we want to do, however, is to track back from the end of the whole disassembly so many lines as the slice which starts with the faulting instruction is long. This leads us to the actual faulting instruction and *then* we tag it. While we're at it, we can drop the sed "g" flag because we address only this one line. Also, if we point to an instruction which changes decoding depending on the slice being objdumped, like a Jcc insn, for example, we do not even tag it as a faulting instruction because the instruction decode changes in the second slice but we use that second format as a regex on the fsrst disassembled buffer and more often than not that instruction doesn't match. Again, simply tag the line which is deduced from the original "<>" marking we've received from the kernel. This also solves the pathologic issue of multiple tagging like this: 29:* 0f 0b ud2 <-- trapping instruction 2b:* 0f 0b ud2 <-- trapping instruction 2d:* 0f 0b ud2 <-- trapping instruction Double tagging example: Code: 34 dd 40 30 ad 81 48 c7 c0 80 f6 00 00 48 8b 3c 30 48 01 c6 b8 ff ff ff ff 48 8d 57 f0 48 39 f7 74 2f 49 8b 4c 24 08 48 8b 47 f0 <48> 39 48 08 75 0e eb 2a 66 90 48 8b 40 f0 48 39 48 08 74 1e 48 All code ======== 0: 34 dd xor $0xdd,%al 2: 40 30 ad 81 48 c7 c0 xor %bpl,-0x3f38b77f(%rbp) 9: 80 f6 00 xor $0x0,%dh c: 00 48 8b add %cl,-0x75(%rax) f: 3c 30 cmp $0x30,%al 11: 48 01 c6 add %rax,%rsi 14: b8 ff ff ff ff mov $0xffffffff,%eax 19: 48 8d 57 f0 lea -0x10(%rdi),%rdx 1d: 48 39 f7 cmp %rsi,%rdi 20: 74 2f je 0x51 22: 49 8b 4c 24 08 mov 0x8(%r12),%rcx 27: 48 8b 47 f0 mov -0x10(%rdi),%rax 2b:* 48 39 48 08 cmp %rcx,0x8(%rax) <-- trapping instruction 2f: 75 0e jne 0x3f 31: eb 2a jmp 0x5d 33: 66 90 xchg %ax,%ax 35: 48 8b 40 f0 mov -0x10(%rax),%rax 39:* 48 39 48 08 cmp %rcx,0x8(%rax) <-- trapping instruction 3d: 74 1e je 0x5d 3f: 48 rex.W Signed-off-by: Borislav Petkov Cc: "H.
