arm: ptdump: rename CONFIG_DEBUG_WX to CONFIG_ARM_DEBUG_WX

2024-02-22T18:24:47+00:00

Patch series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute", v2. This series refactors CONFIG_DEBUG_WX for the 5 architectures implementing CONFIG_GENERIC_PTDUMP First rename stuff in ARM which uses similar names while not implementing CONFIG_GENERIC_PTDUMP. Then define a generic version of debug_checkwx() that calls ptdump_check_wx() when CONFIG_DEBUG_WX is set. Call it immediately after calling mark_rodata_ro() instead of calling it at the end of every mark_rodata_ro(). Then implement a debugfs attribute that can be used to trigger a W^X test at anytime and regardless of CONFIG_DEBUG_WX This patch (of 5): CONFIG_DEBUG_WX is a core option defined in mm/Kconfig.debug To avoid any future conflict, rename ARM version into CONFIG_ARM_DEBUG_WX.

arm: debug: reuse the config DEBUG_OMAP2UART{1,2} for OMAP{3,4,5}

2023-10-26T15:26:15+00:00

Commit d2b310b0234c ("ARM: debug: Use generic 8250 debug_ll for omap2 and omap3/4/5 common uarts") adds address definitions of DEBUG_UART_PHYS for OMAP2, OMAP3, OMAP4 and OMAP5 in ./arch/arm/Kconfig.debug. These definitions depend on DEBUG_OMAP{2,3,4,5}UART{1,2}; however, only DEBUG_OMAP2UART{1,2} are defined in ./arch/arm/Kconfig.debug, and DEBUG_OMAP{3,4,5}UART{1,2} are not defined. Hence, the script ./scripts/checkkconfigsymbols.py warns here on non-existing symbols. Simply reuse the config DEBUG_OMAP2UART{1,2}; there is no need to define separate config symbols for OMAP{3,4,5}. So, just delete the dead references to DEBUG_OMAP{3,4,5}UART{1,2}.

ARM: s3c: remove all s3c24xx support

2023-01-16T08:26:05+00:00

The platform was deprecated in commit 6a5e69c7ddea ("ARM: s3c: mark as deprecated and schedule removal") and can be removed. This includes all files that are exclusively for s3c24xx and not shared with s3c64xx, as well as the glue logic in Kconfig and the maintainer file entries.
