The AFFS filesystem is still in use by m68k community (Link #2), but as there was no code activity and no maintainer, the filesystem appeared on the list of candidates for staging/removal (Link #1). I volunteer to act as a maintainer of AFFS to collect any fixes that might show up and to guard fs/affs/ against another spring cleaning.

Pull powerpc fixes from Michael Ellerman: "A bunch of fixes, mostly for existing code and going to stable. Our memory hot-unplug path wasn't flushing the cache before removing memory. That is a problem now that we are doing memory hotplug on bare metal. Three fixes for the NPU code that supports devices connected via NVLink (ie. GPUs). The main one tweaks the TLB flush algorithm to avoid soft lockups for large flushes. A fix for our memory error handling where we would loop infinitely, returning back to the bad access and hard lockup the CPU. Fixes for the OPAL RTC driver, which wasn't handling some error cases correctly. A fix for a hardlockup in the powernv cpufreq driver. And finally two fixes to our smp_send_stop(), required due to a recent change to use it on shutdown.

Currently, KVM flushes the TLB after a change to the APIC access page address or the APIC mode when EPT mode is enabled. However, even in shadow paging mode, a TLB flush is needed if VPIDs are being used, as specified in the Intel SDM Section 29.4.5. So replace vmx_flush_tlb_ept_only() with vmx_flush_tlb(), which will flush if either EPT or VPIDs are in use.

i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which returns ZERO_SIZE_PTR if i2c_msg.len is zero. Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in case of zero len. Let's check the len against zero before dereferencing buf pointer. This issue was triggered by syzkaller.

Our out-of-line atomics are built with a special calling convention, preventing pointless stack spilling, and allowing us to patch call sites with ARMv8.1 atomic instructions. Instrumentation inserted by the compiler may result in calls to functions not following this special calling convention, resulting in registers being unexpectedly clobbered, and various problems resulting from this. For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of the atomic functions. This has been observed to result in spurious cmpxchg failures, leading to a hang early on in the boot process. This patch avoids such issues by preventing instrumentation of our out-of-line atomics.

smp_send_stop can lock up the IPI path for any subsequent calls, because the receiving CPUs spin in their handler function. This started becoming a problem with the addition of an smp_send_stop call in the reboot path, because panics can reboot after doing their own smp_send_stop. The NMI IPI variant was fixed with ac61c115 ("powerpc: Fix smp_send_stop NMI IPI handling"), which leaves the smp_call_function variant. This is fixed by having smp_send_stop only ever do the smp_call_function once. This is a bit less robust than the NMI IPI fix, because any other call to smp_call_function after smp_send_stop could deadlock, but that has always been the case, and it was not been a problem before.

We can ensure that the timer always runs on one of the policy-cpus. If the timer gets migrated to a cpu outside the policy then re-queue it back on the policy->cpus. This way we can get rid of the smp-call which was being used to set the pstate on the policy->cpus.

The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left. Furthermore, for both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings. Finally, the 'reg' property of a 'nand' node (with the new bindings) gives the IDs of each CS line in use. marvell_nand.c driver first look at the number of CS lines that are present in this property. Better use of_property_count_elems_of_size() than dividing by 4 the size of the number of bytes returned by of_get_property().

It's possible for userspace to control n. Sanitize n when using it as an array index. Note that while it appears that n must be bound to the interval [0,3] due to the way it is extracted from addr, we cannot guarantee that compiler transformations (and/or future refactoring) will ensure this is the case, and given this is a slow path it's better to always perform the masking.
