There used to be a dependency on _PAGE_PRIVILEGED with pte_savedwrite.
But that got dropped by
commit 6a56ccbcf6 ("mm/autonuma: use can_change_(pte|pmd)_writable() to replace savedwrite")
With the change in this patch numa fault pte (pte_protnone()) gets mapped as regular user pte
with RWX cleared (no-access) whereas earlier it used to be mapped _PAGE_PRIVILEGED.
Hash fault handling code gets some WARN_ON added in this patch because
those functions are not expected to get called with _PAGE_READ cleared.
commit 18061c17c8 ("powerpc/mm: Update PROTFAULT handling in the page
fault path") explains the details.

dlpar_memory_remove_by_index() may access beyond the bounds of the
drmem lmb array when the LMB lookup fails to match an entry with the
given DRC index. When the search fails, the cursor is left pointing to
&drmem_info->lmbs[drmem_info->n_lmbs], which is one element past the

The rtas_read_config() and rtas_write_config() functions in
kernel/rtas_pci.c have external linkage and two users in arch/powerpc:
the rtas_pci code itself and the pseries platform's "enhanced error
handling" (EEH) support code.
The prototypes for these functions in asm/ppc-pci.h have until now
been guarded by CONFIG_EEH since the only external caller is the
pseries EEH code. However, this presumably has always generated
warnings when built with !CONFIG_EEH and -Wmissing-prototypes:
arch/powerpc/kernel/rtas_pci.c:46:5: error: no previous prototype for
function 'rtas_read_config' [-Werror,-Wmissing-prototypes]

function 'rtas_write_config' [-Werror,-Wmissing-prototypes]
98 | int rtas_write_config(struct pci_dn *pdn, int where,
int size, u32 val)
The introduction of commit c6345dfa6e3e ("Makefile.extrawarn: turn on
missing-prototypes globally") forces the issue.
The efika and chrp platform code have (static) functions with the same
names but different signatures. We may as well eliminate the potential
for conflicts and confusion by renaming the globally visible versions
as their prototypes get moved out of the CONFIG_EEH-guarded region;
their current names are too generic anyway. Since they operate on
objects of the type 'struct pci_dn *', give them the slightly more
verbose prefix "rtas_pci_dn_" and fix up all the call sites.

Building with GCC with -Warray-bounds enabled there are several warnings
in sstep.c along the lines of:
In function ‘do_byte_reverse’,
inlined from ‘do_vec_load’ at arch/powerpc/lib/sstep.c:691:3,
inlined from ‘emulate_loadstore’ at arch/powerpc/lib/sstep.c:3439:9:

289 | up[2] = byterev_8(up[1]);

arch/powerpc/lib/sstep.c: In function ‘emulate_loadstore’:
arch/powerpc/lib/sstep.c:681:11: note: at offset 16 into object ‘u’ of size 16
681 | } u = {};
| ^
do_byte_reverse() supports a size up to 32 bytes, but in these cases the
caller is only passing a 16 byte buffer. In practice there is no bug,
do_vec_load() is only called from the LOAD_VMX case in emulate_loadstore().
That in turn is only reached when analyse_instr() recognises VMX ops,
and in all cases the size is no greater than 16:
$ git grep -w LOAD_VMX arch/powerpc/lib/sstep.c
arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 1);
arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 2);
arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 4);
arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 16);
Similarly for do_vec_store().
Although the warning is incorrect, the code would be safer if it clamped
the size from the caller to the known size of the buffer. Do that using
min_t().

The cpu_spec is a struct holding various information about the CPU the
kernel is executing on. It's populated early in boot and must not change
after that.
In particular the cpu_features and mmu_features hold the set of
discovered CPU/MMU features and are used to set static keys for each
feature, and do binary patching of assembly. So any change to the
cpu_features/mmu_features later in boot will not be reflected in
the state of the static keys or patched code.
There is already logic to check that cpu_features/mmu_features don't
change, see check_features() in feature-fixups.c.
But as another layer of protection the entire cpu_spec should be read
only after init, annotate it as such.
