commit 188c9c2e0c upstream.
The driver leaves the line speed unchanged in case a requested speed is
not supported. Make sure to handle the case where the current speed is
B0 (hangup) without dividing by zero when determining the clock source.

commit e88906b169 upstream.
The RF sniffers are based on cp210x where the RF frontends
are based on a different USB stack.
RF sniffers can analyze packets meta data including power level
and perform packet injection.
Can be used to perform RF frontend self-test when connected to
a concentrator, ex. arch/arm/boot/dts/imx7d-flex-concentrator.dts

If a file has FI_COMPRESS_RELEASED, all writes for it should not be
allowed. However, as of now, in case of compress_mode=user, writes
triggered by IOCTLs like F2FS_IOC_DE/COMPRESS_FILE are allowed unexpectly,
which could crash that file.
To fix it, let's do not allow F2FS_IOC_DE/COMPRESS_IOCTL if a file already
has FI_COMPRESS_RELEASED flag.
This is the reproduction process:
1. $ touch ./file
2. $ chattr +c ./file
3. $ dd if=/dev/random of=./file bs=4096 count=30 conv=notrunc
4. $ dd if=/dev/zero of=./file bs=4096 count=34 seek=30 conv=notrunc
5. $ sync
6. $ do_compress ./file ; call F2FS_IOC_COMPRESS_FILE
7. $ get_compr_blocks ./file ; call F2FS_IOC_GET_COMPRESS_BLOCKS
8. $ release ./file ; call F2FS_IOC_RELEASE_COMPRESS_BLOCKS
9. $ do_compress ./file ; call F2FS_IOC_COMPRESS_FILE again
10. $ get_compr_blocks ./file ; call F2FS_IOC_GET_COMPRESS_BLOCKS again
This reproduction process is tested in 128kb cluster size.
You can find compr_blocks has a negative value.

Now decompression is being handled in workqueue and it makes read I/O
latency non-deterministic, because of the non-deterministic scheduling
nature of workqueues. So, I made it handled in softirq context only if
possible, not in low memory devices, since this modification will
maintain decompresion related memory a little longer.

Introduce memory mode to supports "normal" and "low" memory modes.
"low" mode is to support low memory devices. Because of the nature of
low memory devices, in this mode, f2fs will try to save memory sometimes
by sacrificing performance. "normal" mode is the default mode and same
as before.

Since commit e3c548323d ("f2fs: let's allow compression for mmap files"),
it has been allowed to compress mmap files. However, in compress_mode=user,
it is not allowed yet. To keep the same concept in both compress_modes,
f2fs_ioc_(de)compress_file() should also allow it.
Let's remove checking mmap files in f2fs_ioc_(de)compress_file() so that
the compression for mmap files is also allowed in compress_mode=user.
