For some reason I managed to trick gcc into create CRC symbols that
are not absolute anymore, but weak.
Make modpost handle this case.
Andrew, this should fix the bizarre warning. Seems like a toolchain

The r1 value is set based on the r0 value as we return to user space.
So tracing tools won't automatically see the right value. Fix this by
generating the correct r1 value in do_syscall_trace_exit() rather
than trying to tamper with the hot path in syscall return.

On the tile architecture, we use the processor clock tick as the time
source. However, when we perform dynamic frequency adjustment and
modify the clock rate of the core, we have to update the timekeeper

This change provides a cpufreq driver for tilegx, and also the
associated machinery to support the fact that we use the core frequency
as the actual timekeeper clock, so we have to go to some trouble to keep

The 64bit __copy_{from,to}_user_inatomic always called

Can as well do the normal conditional resched check out of line.
This saves one function call.

This patch adds EFI stub support for the ARM Linux kernel. The EFI stub
operations similarly to the x86 stub: it is a shim between the EFI firmware
and the normal zImage entry point, and sets up the environment that the
zImage is expecting. This includes loading the initrd (optionaly) and

This patch series adds EFI stub support for the ARM architecture.
Some code that was previously only used by x86/x86_64 is now shared
and has been made more general. The stub for ARM is implemented in
a similar manner to x86 in that it is a shim layer between EFI and
the normal zImage/bzImage boo
No code changes made, just moving functions from x86 arch directory
to common location.
Code is shared using #include, similar to how decompression code
is shared among architectures.

Make efi_free() safely callable with size of 0, similar to free() being
callable with NULL pointers.
Remove size checks that this makes redundant. This also avoids some
size checks in the ARM EFI stub code that will be added as well.

The x86/AMD64 EFI stubs must us a call wrapper to convert between
the Linux and EFI ABIs, so void pointers are sufficient. For ARM,
the ABIs are compatible, so we can directly invoke the function
pointers. The functions that are used by the ARM stub are updated
to match the EFI definitions.

The existing code could fail to allocate depending
on allocation size, as although repeated allocation
attempts were made, none were guaranteed to be page
aligned.

The handle_cmdline_files now takes the option to handle as a string,
and returns the loaded data through parameters, rather than taking
an x86 specific setup_header structure. For ARM, this will be used
to load a device tree blob in addition to initrd images.

Rename them to be more similar, as low_free() could be used to free
memory allocated by both high_alloc() and low_alloc().
high_alloc() -> efi_high_alloc()
low_alloc() -> efi_low_alloc()
low_free() -> efi_free()
