      Make most arch asm/module.h files use asm-generic/module.h · 786d35d4
      由 David Howells 提交于 
      Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.

Also, use the generic definition mod_arch_specific where possible.

To this end, I've defined three new config bools:

 (*) HAVE_MOD_ARCH_SPECIFIC

     Arches define this if they don't want to use the empty generic
     mod_arch_specific struct.

 (*) MODULES_USE_ELF_RELA

     Arches define this if their modules can contain RELA records.  This causes
     the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
     defined by the arch rather than have the core emit an error message.

 (*) MODULES_USE_ELF_REL

     Arches define this if their modules can contain REL records.  This causes
     the Elf_Rel mapping to be emitted and allows apply_relocate() to be
     defined by the arch rather than have the core emit an error message.

Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.

Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

      powerpc: Uprobes port to powerpc · 8b7b80b9
      由 Ananth N Mavinakayanahalli 提交于 
      This is the port of uprobes to powerpc. Usage is similar to x86.

[root@xxxx ~]# ./bin/perf probe -x /lib64/libc.so.6 malloc
Added new event:
  probe_libc:malloc    (on 0xb4860)

You can now use it in all perf tools, such as:

	perf record -e probe_libc:malloc -aR sleep 1

[root@xxxx ~]# ./bin/perf record -e probe_libc:malloc -aR sleep 20
[ perf record: Woken up 22 times to write data ]
[ perf record: Captured and wrote 5.843 MB perf.data (~255302 samples) ]
[root@xxxx ~]# ./bin/perf report --stdio
...

The trap_nr addition patch is a prereq.

      powerpc: select PPC_CLOCK unconditionally for FSL_SOC · 6d4ae2dd
      由 Shawn Guo 提交于 
      Freescale PowerPC SoCs share a number of IP blocks with Freescale
ARM/IMX SoCs, FlexCAN, SSI, FEC, eSDHC, USB, etc.  There are some
effort consolidating those drivers to make them work for both
architectures.

One outstanding difference between two architectures is ARM/IMX will
turn off module clocks during platform initialization for power saving
and expects drivers manage clocks using clk API, while PowerPC
mostly does not do that, and thus does not always build in clk API.

Listing all those driver Kconfig options in "select PPC_CLOCK if" seems
not scalable for long term maintenance, and could easily introduce
Kconfig recursive dependency.  This patch chooses to select PPC_CLOCK
unconditionally for FSL_SOC to always build clk API for PowerPC in.
