We are using metricbeat 7.17.3 as of this post, and are receiving an error on several systems which are configured to use the linux.pageinfo metricset, also reported [here](https://discuss.elastic.co/t/error-fetching-data-for-metricset-linux-pageinfo/297049), but has since auto closed.

```
This _appears_ to be due to the way pagetypeinfo is displayed when over 100000, and the way the module parses each column expecting integers, as seen roughly [here](https://github.com/elastic/beats/blob/v7.17.3/metricbeat/module/linux/pageinfo/reader.go#L50-L101) in the regex expresion and subsequent parsing of an expected integer.
Example:
`>100000` is reported by pagetypeinfo, but is more accurately represented as the total count of `213501` as seen below.

I'm also seeing this issue. As mentioned, `pagetypeinfo` returns more info on page migration types, but less accurate totals than `buddyinfo` for large quantities. From the kernel code [here](https://github.com/torvalds/linux/blob/master/mm/vmstat.c#L1501-L1515), you can see `pageinfotype` truncates any count over 100k and just displays `>100000`.
The regex for this should be corrected for the `pagetypeinfo` stats to at least handle the `>` indication and instead of _emulating_ the stats for `buddyinfo`, it should be called directly to get proper totals.
