Subject: [PATCH v2] mm: Fix some typos in mm module
From: "jianyun.gao" <jianyungao89@...il.com>
Below are some typos in the code comments:
intevals ==> intervals
addesses ==> addresses
unavaliable ==> unavailable
facor ==> factor
droping ==> dropping
exlusive ==> exclusive
decription ==> description
confict ==> conflict
desriptions ==> descriptions
otherwize ==> otherwise
vlaue ==> value
cheching ==> checking
exisitng ==> existing
modifed ==> modified
differenciate ==> differentiate
refernece ==> reference
permissons ==> permissions
indepdenent ==> independent
spliting ==> splitting
Just fix it.
Signed-off-by: jianyun.gao <jianyungao89@...il.com>

The fix for typos in the hugetlb sub-module has been added.
