bug: Use normal relative pointers in 'struct bug_entry'

2022-05-19T21:46:10Z

With CONFIG_GENERIC_BUG_RELATIVE_POINTERS, the addr/file relative pointers are calculated weirdly: based on the beginning of the bug_entry struct address, rather than their respective pointer addresses. Make the relative pointers less surprising to both humans and tools by calculating them the normal way.

arm64: asm-bug: Renumber macro local labels to avoid clashes

2017-10-25T14:57:15Z

Currently ASM_BUG() and its constituent macros define local assembler labels 0, 1 and 2 internally, which carries a high risk of clash with callers' labels and consequent mis-assembly. This patch gives the labels a big random offset to minimise the chance of such errors. Signed-off-by: Dave Martin Signed-off-by: Will Deacon

arm64: Add ASM_BUG()

2017-08-08T15:28:13Z

Currently. we can only use BUG() from C code, though there are situations where we would like an equivalent mechanism in assembly code. This patch refactors our BUG() definition such that it can be used in either C or assembly, in the form of a new ASM_BUG(). The refactoring requires the removal of escape sequences, such as '\n' and '\t', but these aren't strictly necessary as we can use ';' to terminate assembler statements. The low-level assembly is factored out into , with retained as the C wrapper. Signed-off-by: Mark Rutland Cc: Ard Biesheuvel Cc: Catalin Marinas Cc: Dave Martin Cc: James Morse Cc: Will Deacon
