bbc448c541ed90d52f9ec22f17394304e3bf170e - mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQ

Fri, 28 Aug 2026 16:07:33 +0200

mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQOn I6500 CPU cores, lld and scd give no ordering guarantees (same as allother instructions). To respect the assumption that arch_cmpxchg() isfully ordered, we must inject sync instructions above and below ourlld/scd loops using the already in place WEAK_REORDERING_BEYOND_LLSCinfrastructure.Otherwise, bad things can happen:[ 34.054496] CPU 3 Unable to handle kernel paging request at virtual address 0000000000000000, epc == a80000080838e01c, ra == a80000080838dfc4[ 34.054559] Oops[#1]:[ 34.069561] CPU: 3 UID: 0 PID: 170 Comm: pipe_race Not tainted 7.2.0-rc6-01553-gb73c35220968-dirty #103 VOLUNTARY[ 34.079932] Hardware name: Mobile EyeQ5 MP5 Evaluation board[ 34.085592] $ 0 : 0000000000000000 0000000000000001 0000000000000000 0000000000000000[ 34.093616] $ 4 : a800000808ee2618 000000000b7a879d 0000000000001000 0000000000000000[ 34.101638] $ 8 : 0000000000e3f2c9 0000000000000000 a800000808a2a9f8 0000000000000000[ 34.109660] $12 : a8000008139ffcd8 ffffffff84080018 a80000080837fae0 7878787878787878[ 34.117682] $16 : a800000807e82940 0000000000001000 0000000000000000 0000000000000000[ 34.125704] $20 : a800000802920e00 a8000008139ffdf8 a800000802649400 0000000000e3f2c9[ 34.133726] $24 : 0000000000000006 00000001200406e0[ 34.141783] $28 : a8000008139fc000 a8000008139ffd10 0000000000e3f2c8 a80000080838dfc4[ 34.149837] epc : a80000080838e01c anon_pipe_read+0xd4/0x428[ 34.155697] ra : a80000080838dfc4 anon_pipe_read+0x7c/0x428[ 34.161549] Status: 140000e3 KX SX UX KERNEL EXL IE[ 34.166551] Cause : 40800408 (ExcCode 02)[ 34.170574] BadVA : 0000000000000000[ 34.174161] PrId : 0001b028 (MIPS I6500)[ 34.178183] Process pipe_race (pid: 170, threadinfo=000000005ca35720, task=00000000e1013890, tls=000000014ebbb780)[ 34.188568] Stack : a800000802649400 0000000000000000 0000000000000000 a8000008139ffdd0[ 34.196623] 0000000000000fba a800000808ee0000 0000000000000001 a8000008130c3e80[ 34.204676] a8000008080d1280 a8000008139ffd58 a8000008139ffd58 1dbd2b22ea1dd500[ 34.212729] a800000802649400 a800000808ee0000 ffffffffffffffea 0000000000000001[ 34.220783] 0000000000001000 0000000000000000 00000001200ae518 ffffffffffffffff[ 34.228836] 000000fffbe0e530 a80000080837edf4 000000fffbe0e530 0000000000000000[ 34.236890] 0000000000000000 0000000000000000 000000014ebb55a0 0000000000001000[ 34.244943] 0000000000000001 a800000802649400 0000000000000000 0000000000000000[ 34.252996] 0000000000000000 0000400400000000 0000000000000000 1dbd2b22ea1dd500[ 34.261049] 00000000140000e3 a800000802649400 a800000802649400 a800000808ee0000[ 34.269103] ...[ 34.271568] Call Trace:[ 34.274026] [] anon_pipe_read+0xd4/0x428[ 34.279533] [] vfs_read+0x25c/0x318[ 34.284607] [] ksys_read+0x104/0x138[ 34.289763] [] syscall_common+0x44/0x68[ 34.295187][ 34.296689] Code: f84000cf 02209825 de020010 d8400004 02002825 0040f809 02802025 f84000c3[ 34.306504][ 34.308099] ---[ end trace 0000000000000000 ]---My initial reproducer was the xdp-tools test suite.

The config switch exists, but architecture code still exposes the legacy functionality even disabled. Clean this up by adding the missing guards and validating at build time that the VDSO is legacy free if disabled. - Consolidate the VDSO related config options in core and drivers, which removes some non-sensical dependencies and quite an amount of #ifdeffery. - Clean up the PAGE_SIZE definition maze* tag 'timers-vdso-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) random: vDSO: Drop custom PAGE_SIZE definitions LoongArch: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/timer-riscv: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/arm_arch_timer: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/mips-gic-timer: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery MIPS: csrc-r4k: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery vDSO: Make clockmode constants available without CONFIG_GENERIC_GETTIMEOFDAY kbuild: Support generated asm-headers in subdirectories vdso: Rename HAVE_GENERIC_VDSO to VDSO_DATASTORE vdso: Drop HAVE_GENERIC_VDSO from architecture kconfig files vdso: Automatically select HAVE_GENERIC_VDSO if necessary MIPS: vdso: Stop using CONFIG_HAVE_GENERIC_VDSO vdso: Remove the dependency on HAVE_GENERIC_VDSO from ARCH_HAS_VDSO_ARCH_DATA futex: Remove dependency on HAVE_GENERIC_VDSO from FUTEX_ROBUST_UNLOCK vdso/gettimeofday: Verify COMPAT_32BIT_TIME interactions sparc: vdso: Respect COMPAT_32BIT_TIME MIPS: VDSO: Respect COMPAT_32BIT_TIME powerpc/vdso: Respect COMPAT_32BIT_TIME ARM: VDSO: Respect COMPAT_32BIT_TIME arm64: vdso32: Respect COMPAT_32BIT_TIME ...
