linux-toradex.git/kernel/debug/gdbstub.c, branch v7.0-rc5 Linux kernel for Apalis and Colibri modules kernel.h: drop hex.h and update all hex.h users 2026-01-21T03:44:19+00:00 Randy Dunlap rdunlap@infradead.org 2025-12-15T00:51:56+00:00 24c776355f4097316a763005434ffff716aa21a8 Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of hex.h interfaces to directly #include <linux/hex.h> as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of <linux/hex.h> in the entire source tree have been updated if needed (if not already #included).

Currently although the calls are paired correctly they are needlessly smeared across three different functions. Worse this also results in code to drive polled I/O being called with breakpoints activated which, in turn, needlessly increases the set of functions that will recursively trap if breakpointed. Fix this by moving the activation of breakpoints into the debug core.
