[PATCH AUTOSEL 5.15 1/7] ASoC: rsnd: don't indicate warning on rsnd_kctrl_accept_runtime()

by Sasha Levin

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> [ Upstream commit c3fc002b206c6c83d1e3702b979733002ba6fb2c ] rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate (= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it (A): "SRC Out Rate Switch" (B): "SRC Out Rate" // it calls (1) (A): can be called anytime (B): can be called only runtime, and will indicate warning if it was used at non-runtime. To use runtime convert rate (= Synchronous SRC Mode), user might uses command in below order. (X): > amixer set "SRC Out Rate" on > aplay xxx.wav & (Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz (Y): calls B (X): calls both A and B. In this case, when user calls (X), it calls both (A) and (B), but it is not yet start running. So, (B) will indicate warning. This warning was added by commit b5c088689847 ("ASoC: rsnd: add warning message to rsnd_kctrl_accept_runtime()"), but the message sounds like the operation was not correct. Let's update warning message.

[PATCH AUTOSEL 6.6 01/20] bpf: unify VM_WRITE vs VM_MAYWRITE use in BPF map mmaping logic

by Sasha Levin

From: Andrii Nakryiko <andrii(a)kernel.org> [ Upstream commit 98671a0fd1f14e4a518ee06b19037c20014900eb ] For all BPF maps we ensure that VM_MAYWRITE is cleared when memory-mapping BPF map contents as initially read-only VMA. This is because in some cases BPF verifier relies on the underlying data to not be modified afterwards by user space, so once something is mapped read-only, it shouldn't be re-mmap'ed as read-write. As such, it's not necessary to check VM_MAYWRITE in bpf_map_mmap() and map->ops->map_mmap() callbacks: VM_WRITE should be consistently set for read-write mappings, and if VM_WRITE is not set, there is no way for user space to upgrade read-only mapping to read-write one. This patch cleans up this VM_WRITE vs VM_MAYWRITE handling within bpf_map_mmap(), which is an entry point for any BPF map mmap()-ing logic. We also drop unnecessary sanitization of VM_MAYWRITE in BPF ringbuf's map_mmap() callback implementation, as it is already performed by common code in bpf_map_mmap(). Note, though, that in bpf_map_mmap_{open,close}() callbacks we can't drop VM_MAYWRITE use, because it's possible (and is outside of subsystem's control) to have initially read-write memory mapping, which is subsequently dropped to read-only by user space through mprotect(). In such case, from BPF verifier POV it's read-write data throughout the lifetime of BPF map, and is counted as "active writer". But its VMAs will start out as VM_WRITE|VM_MAYWRITE, then mprotect() can change it to just VM_MAYWRITE (and no VM_WRITE), so when its finally munmap()'ed and bpf_map_mmap_close() is called, vm_flags will be just VM_MAYWRITE, but we still need to decrement active writer count with bpf_map_write_active_dec() as it's still considered to be a read-write mapping by the rest of BPF subsystem. Similar reasoning applies to bpf_map_mmap_open(), which is called whenever mmap(), munmap(), and/or mprotect() forces mm subsystem to split original VMA into multiple discontiguous VMAs. Memory-mapping handling is a bit tricky, yes.

Using cmn_interrupt_2_enable to configure Tag, Data RAM ECC interrupts would lead to issues like double handling of the interrupts (EL1 and EL3) as cmn_interrupt_2_enable is meant to be configured for interrupts which needs to be handled by EL3. EL1 LLCC EDAC driver needs to use cmn_interrupt_0_enable register to configure Tag, Data RAM ECC interrupts instead of cmn_interrupt_2_enable.
