When unloading the call to pm_runtime_put_sync_suspend() will attempt to
turn the GPU cores off, however panfrost_device_fini() will have turned
the clocks off. This leads to the hardware locking up.

Having pt_regs on-stack is unfortunate, it's 168 bytes. Since it isn't
actually used, make it a static variable. This both gets if off the

Hi,
Steve reported an NMI stack overflow when running perf and function tracing
together. Thomas found that we had 4 copies of struct perf_sample_data
on-stack.
These here patches reduce that to 2 copies and half the size of it.
So just for perf_sample_data we go from 4*384=1536 to 2*192=384 byt
__perf_output_begin() has an on-stack struct perf_sample_data in the
unlikely case it needs to generate a LOST record. However, every call
to perf_output_begin() must already have a perf_sample_data on-stack.

I am, you can take it. I'll merge the dt patches through arm-soc

The system call number is used in a a couple of places, in particular
ptrace, seccomp and /proc//syscall.
The last one apparently never worked reliably on ARM for tasks
that are not currently getting traced.
Storing the syscall number in the normal entry path makes it work,
From: Arnd Bergmann
These mimic the behavior of get_user and put_user, except
for domain switching, address limit checking and handling
of mismatched sizes, none of which are relevant here.
To work with pre-Armv6 kernels, this has to avoid TUSER()
inside of the new macros, the new approach passe
From: Arnd Bergmann
The epoll_wait() system call wrapper is one of the remaining users of
the set_fs() infrasturcture for Arm. Changing it to not require set_fs()
is rather complex unfortunately.
The approach I'm taking here is to allow architectures to override
the code that copies the output t
From: Arnd Bergmann
sys_oabi_semtimedop() is one of the last users of set_fs() on Arm. To
remove this one, expose the internal code of the actual implementation
that operates on a kernel pointer and call it directly after copying.
There should be no measurable impact on the normal execution of t
From: Arnd Bergmann
ARM uses set_fs() and __get_user() to allow the stack dumping code to
access possibly invalid pointers carefully. These can be changed to the
simpler get_kernel_nofault(), and allow the eventual removal of set_fs().
dump_instr() will print either kernel or user space pointers

In isolate_migratepages_block, if we have too many isolated pages and
nr_migratepages is not zero, we should try to migrate what we have
without wasting time on isolating.

In isolate_migratepages_block, when cc->alloc_contig is true, we are
able to isolate compound pages, nr_migratepages and nr_isolated did not
count compound pages correctly, causing us to isolate more pages than we
thought. Use thp_nr_pages to count pages. Otherwise, we might be trapp
