bpf_arch_text_copy is used to dump JITed binary to RX page, allowing
multiple BPF programs to share the same page. Use the newly introduced
patch_instructions() to implement it.

patch_instruction() entails setting up pte, patching the instruction,
clearing the pte and flushing the tlb. If multiple instructions need
to be patched, every instruction would have to go through the above
drill unnecessarily. Instead, introduce patch_instructions() function
that sets up the pte,
Most BPF programs are small, but they consume a page each. For systems
with busy traffic and many BPF programs, this may also add significant
pressure on instruction TLB. High iTLB pressure usually slows down the
whole system causing visible performance degradation for production
workloads.

Dave Woodhouse reported that we now nest calls to
arch_enter_lazy_mmu_mode(). That was inadvertent, but in principle we
should allow it. On further investigation, Juergen already fixed it
for Xen, but didn't tell anyone. Fix it for Sparc & PowerPC too.
This may or may not help fix the problem

There is still a considerable user base for the PS3, so we
must keep the ps3-gelic-wireless driver.

has some devices with old software.

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context. We fix it by calling
pm_runtime_disable when error returns.

Greetings,
Thank you Florian. I have tried the changes suggested by you and it
fixes the issue. With the suggested changes the problem is not seen.
