*	hugetlb: new sysfs interface	Nishanth Aravamudan	2008-07-24	1	-0/+23
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Provide new hugepages user APIs that are more suited to multiple hstates in sysfs. There is a new directory, /sys/kernel/hugepages. Underneath that directory there will be a directory per-supported hugepage size, e.g.: /sys/kernel/hugepages/hugepages-64kB /sys/kernel/hugepages/hugepages-16384kB /sys/kernel/hugepages/hugepages-16777216kB corresponding to 64k, 16m and 16g respectively. Within each hugepages-size directory there are a number of files, corresponding to the tracked counters in the hstate, e.g.: /sys/kernel/hugepages/hugepages-64/nr_hugepages /sys/kernel/hugepages/hugepages-64/nr_overcommit_hugepages /sys/kernel/hugepages/hugepages-64/free_hugepages /sys/kernel/hugepages/hugepages-64/resv_hugepages /sys/kernel/hugepages/hugepages-64/surplus_hugepages Of these files, the first two are read-write and the latter three are read-only. The size of the hugepage being manipulated is trivially deducible from the enclosing directory and is always expressed in kB (to match meminfo).

*	Documentation: correct overcommit caveat in hugetlbpage.txt	Nishanth Aravamudan	2008-04-16	1	-4/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	As shown by Gurudas Pai recently, we can put hugepages into the surplus state (by echo 0 > /proc/sys/vm/nr_hugepages), even when /proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to allow the original goal (shrink the static pool to 0) to succeed (we are converting hugepages to surplus because they are in use). However, the documentation does not accurately reflect this case. Update it.

*	Documentation: update hugetlb information	Nishanth Aravamudan	2007-12-18	1	-6/+29
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The hugetlb documentation has gotten a bit out of sync with the current code. Updated the sysctl file to refer to Documentation/vm/hugetlbpage.txt. Update that file to contain the current state of affairs (with the newer named sysctl in place).

\| \| \| \| \| \| \| \| \| \| \| \|	Add new line of /proc/meminfo output. Explain the HugePage_ lines in /proc/meminfo (from Bill Irwin).

\| \| \| \| \| \| \| \| \| \| \| \| \|	Updates to Documentation/vm/hugetlbpage.txt: - there's no need to select HUGETLB_PAGE manually and it's no longer under the processor menu.

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-17	1	-0/+284
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
