Subject: [PATCH] Change the default page size to 64KiB on Aarch64 Linux
|
|
|
|
This updates the configuration script to set the default page size to
|
|
64KiB on Aarch64 Linux. This is motivated by compatibility as a build
|
|
configured for a 64KiB page will work on kernels that use the smaller
|
|
4KiB or 16KiB pages, whereas the reverse is not true.
|
|
|
|
To make the configured page size setting more visible, the script now
|
|
displays the page size when printing the configuration results.
|
|
|
|
Users that want to override the page size in to choose a smaller value
|
|
can still do so with the --with-lg-pagesize configuration option.
