The tlb_remove_ptdesc()/tlb_remove_table() is specially designed for page
table pages, and now all architectures have been converted to use it to
remove page table pages. So let's remove tlb_remove_page_ptdesc(), it
currently has no users and should not be used for page table pages.

The x86 has already been converted to use struct ptdesc, so convert it to
use tlb_remove_ptdesc() instead of tlb_remove_table().

To support fast gup, the commit 69be3fb111e7 ("riscv: enable
MMU_GATHER_RCU_TABLE_FREE for SMP && MMU") did the following:
1) use tlb_remove_page_ptdesc() for those platforms which use IPI to
perform TLB shootdown
2) use tlb_remove_ptdesc() for those platforms which use SBI to perform
TLB s
Now, the nine architectures of csky, hexagon, loongarch, m68k, mips,
nios2, openrisc, sh and um do not select CONFIG_MMU_GATHER_RCU_TABLE_FREE,
and just call pagetable_dtor() + tlb_remove_page_ptdesc() (the wrapper of
tlb_remove_page()). This is the same as the implementation of
tlb_remove_{ptdesc|
Now only arm will call tlb_remove_ptdesc()/tlb_remove_table() when
CONFIG_MMU_GATHER_TABLE_FREE is disabled. In this case, the type of the
table parameter is actually struct ptdesc * instead of struct page *.
Since struct ptdesc still overlaps with struct page and has not been
separated from it, f
All callers of tlb_remove_ptdesc() pass it a pointer of struct ptdesc, so
let's change the pt parameter from void * to struct ptdesc * to perform
a type safety check.

Changes in v2:
- add [PATCH v2 2/6] (Peter Zijlstra)
- remove [PATCH 4/5] and add [PATCH v2 5/6]
- rebase onto the next-20250224
Hi all,
As suggested by Peter Zijlstra below [1], this series aims to remove
tlb_remove_page_ptdesc().
: Fundamentally tlb_remove_page() is about removing *pages

glibc added support for .gnu.hash in 2006 and .hash has been obsoleted
far before the first LoongArch CPU was taped. Using
--hash-style=sysv might imply unaddressed issues and confuse readers.
Some architectures use an explicit --hash-style=both here, but
DT_GNU_HASH has already been supported by
When RISC-V borned, DT_GNU_HASH had already became the de-facto
standard so DT_HASH is just wasting storage space. Remove the explicit

which is most likely "gnu" (i.e. generating only DT_GNU_HASH, no
DT_HASH).

For riscv, csky, and LoongArch, GNU hash had already become the de-facto

without GNU hash support, and the traditional SysV hash is just wasting
space for them.
