The series adds cross compiler support for BPF samples and fixes issues building for arm64.
Tested on my arm64 platform with good results, for x86 I have only build tested it. There are no errors on building, however there is a build warning for x86 which I haven't yet gotten rid off (I believe the warning itself isn't of consequence but rather a result of using the preprocessor in this way). I appreciate any help testing for x86 and looking forward to any feedback on the patches, thanks!
v2 just adds Juri's correct email address as he's interested in this work. Sorry about the noise, thanks!
Joel Fernandes (5): samples/bpf: Use getppid instead of getpgrp for array map stress samples/bpf: Enable cross compiler support samples/bpf: Fix inline asm issues building samples on arm64 samples/bpf: Fix pt_regs issues when cross-compiling samples/bpf: Add documentation on cross compilation
