The Generic Counter chrdev interface expects users to supply component

know what component ID belongs to which extension this information must

We now have three places within the same file doing the same operation
of freeing this pointer and setting it anew. A helper make this
arguably easier to read, so add one.

When retrying a deferred probe, any old defer reason string should be
discarded. Otherwise, if the probe is deferred again at a different spot,
but without setting a message, the now incorrect probe reason will remain.
This was observed with the i.MX I2C driver, which ultimately failed
to probe du

The DTPM framework is looking for upstream SoC candidates to share the
power numbers.
We can see around different numbers but the one which seems to be
consistent with the initial post for the values on the CPUs can be
found in the patch https://lore.kernel.org/patchwork/patch/810159/

Similarly to the work done earlier with writes, this series
converts signal32 to using user_read_access_begin/end and
unsafe_get_user() and friends.
Applies on to of the signal64 series, ie on merge-test (ca6e327fefb2)

Similarly to commit 5cf773fc8f37 ("powerpc/uaccess: Also perform
64 bits copies in unsafe_copy_to_user() on ppc32")
ppc32 has an efficiant 64 bits unsafe_get_user(), so also use it in
order to unroll loops more.

In the same way as commit 14026b94ccfe ("signal: Add
unsafe_put_compat_sigset()"), this time add
unsafe_get_compat_sigset() macro which is the 'unsafe'
version of get_compat_sigset()
For the bigendian, use unsafe_get_user() directly
to avoid intermediate copy through the stack.

Convention is to prefix functions with __unsafe_ instead of
suffixing it with _unsafe.
Rename save_user_regs_unsafe() and save_general_regs_unsafe()
accordingly, that is respectively __unsafe_save_general_regs() and
__unsafe_save_user_regs().

In preparation of using user_access_begin/end in restore_user_regs(),
move the access_ok() inside the function.
It makes no difference as the behaviour on a failed access_ok() is
the same as on failed restore_user_regs().

Add unsafe_get_user_sigset() and transform PPC32 get_sigset_t()
into an unsafe version unsafe_get_sigset_t().
Then convert do_setcontext() and do_setcontext_tm() to use
user_read_access_begin/end.
