Hi,
Since Mike's patches (make hugetlb put_page safe for all calling contexts[1])
applied into the next-20210412. We can move forward on this patch series now.
This patch series will free some vmemmap pages(struct page structures)
associated with each HugeTLB page when preallocated to save memory
Move bootmem info registration common API to individual bootmem_info.c.
And we will use {get,put}_page_bootmem() to initialize the page for the
vmemmap pages or free the vmemmap pages to buddy in the later patch.
So move them out of CONFIG_MEMORY_HOTPLUG_SPARSE. This is just code
movement without a
The option HUGETLB_PAGE_FREE_VMEMMAP allows for the freeing of
some vmemmap pages associated with pre-allocated HugeTLB pages.
For example, on X86_64 6 vmemmap pages of size 4KB each can be
saved for each 2MB HugeTLB page. 4094 vmemmap pages of size 4KB
each can be saved for each 1GB HugeTLB page.

For HugeTLB page, there are more metadata to save in the struct page.
But the head struct page cannot meet our needs, so we have to abuse
other tail struct page to store the metadata. In order to avoid
conflicts caused by subsequent use of more tail struct pages, we can
gather these discrete indexe
Every HugeTLB has more than one struct page structure. We __know__ that
we only use the first 4 (__NR_USED_SUBPAGE) struct page structures
to store metadata associated with each HugeTLB.
There are a lot of struct page structures associated with each HugeTLB
page. For tail pages, the value of compo
In the subsequent patch, we should allocate the vmemmap pages when
freeing a HugeTLB page. But update_and_free_page() can be called
under any context, so we cannot use GFP_KERNEL to allocate vmemmap
pages. However, we can defer the actual freeing in a kworker to
prevent from using GFP_ATOMIC to all
When we free a HugeTLB page to the buddy allocator, we need to allocate
the vmemmap pages associated with it. However, we may not be able to
allocate the vmemmap pages when the system is under memory pressure. In
this case, we just refuse to free the HugeTLB page. This changes behavior
in some corn
Add a kernel parameter hugetlb_free_vmemmap to enable the feature of
freeing unused vmemmap pages associated with each hugetlb page on boot.
We disables PMD mapping of vmemmap pages for x86-64 arch when this
feature is enabled. Because vmemmap_remap_free() depends on vmemmap
being base page mapped
The parameter of memory_hotplug.memmap_on_memory is not compatible with
hugetlb_free_vmemmap. So disable it when hugetlb_free_vmemmap is
enabled.

Hi,
This small series adds the TJA1103 PHY driver.
Changes in v2:
- implemented genphy_c45_pma_suspend/genphy_c45_pma_suspend
- set default internal delays set to 2ns(90 degrees)
- added "VEND1_" prefix to the register definitions
- disable rxid in case of txid
- disable txid in case of rxid
Add driver for tja1103 driver and for future NXP C45 PHYs.

Although 'err' has been initialized to -ENOMEM, but it will be reassigned
by the "err = unwind__prepare_access(...)" statement in the for loop. So

For debugging JITs, dumping the JITed image to kernel log is discouraged,
"bpftool prog dump jited" is much better way to examine JITed dumps.
