Fixes ubsan complaints Signed-off-by: Pedro Falcato <[email protected]>
This helps debug held spinlocks, et al. We can quickly fix it up and see if a next call hangs indefinitely. Signed-off-by: Pedro Falcato <[email protected]>

Add anon_vma, which allows us to do the reverse anon page -> vma mapping. Similar to the original anon_vma design for Linux. Signed-off-by: Pedro Falcato <[email protected]>
Includes swap parsing, mkswap, swapon(1) and swapon(2). Does _not_ include actual swapping yet. Signed-off-by: Pedro Falcato <[email protected]>
Add swapping of anon pages to disk. Also, while we're at it, perform _a lot_ of miscellaneous refactoring and moving around of code, including adding proper GFP flags in a bunch of places, some CHECKs, a bunch of page fault work. This is not perfect but I'm working on it. Also fix the UART8250 ACPI and DT builds. This disables the ARM64 builds in CI because they're broken. Signed-off-by: Pedro Falcato <[email protected]>

Add TYPESAFE_BY_RCU support. These caches guarantee type stability of objects without the need for kfree_rcu or similar (under the RCU read lock). They do so by only reclaiming slabs after an RCU quiescent period has passed. This patch also adds ctor support. While we're at it, use TYPESAFE_BY_RCU for anon_vma, which was the original intended usage. Signed-off-by: Pedro Falcato <[email protected]>
