This is unexpected and undesirable as memory.low is supposed to express non-OOMing memory priorities between cgroups. The reason for this is proportional memory.low reclaim. When cgroups are below their memory.low threshold, reclaim passes them over in the first round, and then retries if it couldn't find pages anywhere else. But when cgroups are slightly above their memory.low setting, page scan force is scaled down and diminished in proportion to the overage, to the point where it can cause reclaim to fail as well - only in that case we currently don't retry, and instead trigger OOM. To fix this, hook proportional reclaim into the same retry logic we have in place for when cgroups are skipped entirely. This way if reclaim fails and some cgroups were scanned with diminished pressure, we'll try another full-force cycle before giving up and OOMing.

However, this does not work for addresses where addr > 0 && addr < KFENCE_POOL_SIZE. This can be the case on NULL-deref where addr > 0 && addr < PAGE_SIZE or any other faulting access with addr < KFENCE_POOL_SIZE. While the kernel would likely crash, the stack traces and report might be confusing due to double faults upon KFENCE's attempt to unprotect such an address. Fix it by just checking that __kfence_pool != NULL instead.

It turns out that some user-space applications use these uapi header files, so even though the only user of the interface is an old driver that was moved to staging, moving the header files causes unnecessary pain. Generally, we really don't want user space to use kernel headers directly (exactly because it causes pain when we re-organize), and instead copy them as needed. But these things happen, and the headers were in the uapi directory, so I guess it's not entirely unreasonable.

This reverts commit ce78ffa3ef1681065ba451cfd545da6126f5ca88. Wren and Nicolas reported that ath11k was failing to initialise QCA6390 Wi-Fi 6 device with error: qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22 Commit ce78ffa3ef16 ("net: really fix the build..."), introduced in v5.14-rc5, caused this regression in qrtr. Most likely all ath11k devices are broken, but I only tested QCA6390. Let's revert the broken commit so that ath11k works again.
