selftest testcases to verify EBB interface. instruction_count_test.c
testcase needs a fixed loop function to count overhead. Instead of
using the thirty_two_instruction_loop() in fixed_instruction_loop.S

I'd rather you didn't. It's not well tested and we ignore it entirely on
some platforms because it causes bugs. Eventually I'd like to remove it.

Aligning address to page boundary allows flush_tlb_kernel_range()
to know it's a single page flush and use tlbie instead of tlbia.
On 603 we now have the following code in first leg of
change_page_attr():
2c: 55 29 00 3c rlwinm r9,r9,0,0,30
30: 91 23 00 00 stw
In the same spirit as commit 63f501e07a85 ("powerpc/8xx: Simplify TLB
handling"), simplify flush_tlb_kernel_range() for 8xx.
8xx cannot be SMP, and has 'tlbie' and 'tlbia' instructions, so
an inline version of flush_tlb_kernel_range() for 8xx is worth it.
With this page, first leg of

The kernel changes needed to add support for crash hotplug support for

Two new members fdt_index and fdt_index_valid are added in kimage_arch

Two major changes are done to enable the crash CPU hotplug handler.
Firstly, updated the kexec_load path to prepare kimage for hotplug
changes and secondly, implemented the crash hotplug handler itself.
On the kexec load path, memsz allocation of crash FDT segment is
updated to ensure that it has
The option CRASH_HOTPLUG enables, in kernel update to kexec segments on

Make the update_cpus_node function non-static and export it for
usage in other kexec components.
The update_cpus_node definition is moved to core_64.c so that it
can be used with both kexec_load and kexec_file_load system calls.

This patch series implements the crash hotplug handler on PowerPC introduced

The Problem:
Post hotplug/DLPAR events the capture kernel holds stale information about the

So far the RELACOUNT tag from the ELF header was containing the exact
number of R_PPC_RELATIVE/R_PPC64_RELATIVE relocations. However the LLVM's
recent change [1] make it equal-or-less than the actual number which
makes it useless.
This replaces RELACOUNT in zImage loader with a pair of RELASZ and

Today, hp_jack_event and mic_jack_event always return 0. However,
snd_soc_dapm_disable_pin and snd_soc_dapm_enable_pin may return a
