Replace HTTP links with HTTPS ones: documentation Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

docs/scripts/gdb: add necessary make scripts_gdb step In order to debug the kernel successfully with gdb you need to run 'make scripts_gdb' nowadays. This was changed with the following commit: Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb constants.py") In order to have a complete guide for beginners this remark should be added to the offial documentation.

scripts/gdb: add lx_current support for arm64 arm64 uses SP_EL0 to save the current task_struct address. While running in EL0, SP_EL0 is clobbered by userspace. So if the upper bit is not 1 (not TTBR1), the current address is invalid. This patch checks the upper bit of SP_EL0, if the upper bit is 1, lx_current() of arm64 will return the derefrence of current task. Otherwise, lx_current() will tell users they are running in userspace(EL0). While arm64 is running in EL0, it is actually pointless to print current task as the memory of kernel space is not accessible in EL0.
