v2: rewrite commit message
tools/build/featur
Even if --symfs is used to point to the debug binaries, we send in the
non-debug filenames to libunwind, which leads to libunwind not finding
the debug frame. Fix this by preferring the file in --symfs, if it is
available.

Since both DEBUG_SET_MODULE_RONX and DEBUG_RODATA depend on MMU, we'll
never get to this code on !MMU so this ifdef build fix should be ok.

Provide a delay timer using the lower 32-bits of the global timer so
that we can use that instead of having to calibrating delays.

There's Documentation/features/ which lists the status of architecture

Hi,
I received some reports of mkfs.ext4 on an SD card triggering the OOM
killer on a swapless system with a low amount of free memory. I have
made a reproducible setup of this by using null_blk with a large
completion delay. The problem appears to be that we do not throttle to
the level of vm_d
The initial value of global_wb_domain.dirty_limit set by
writeback_set_ratelimit() is zeroed out by the memset in
wb_domain_init().
