2008-07-16force offline the processor during hot-removalZhang Rui
The ACPI device node for the cpu has already been unregistered when acpi_processor_handle_eject is called. Thus we should offline the cpu and continue, rather than a failure here. http://bugzilla.kernel.org/show_bug.cgi?id=9772 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>
2008-07-16fix a deadlock issue when poking "eject" fileZhang Rui
"/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method and eject a device in user space. But system hangs when poking the "eject" file because that the device hot-removal code invoke the driver .remove method which will try to remove the "eject" file as a result. Queues the hot-removal function for deferred execution in this patch. http://bugzilla.kernel.org/show_bug.cgi?id=9772 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>

2008-07-16Fix MIPS cross-compile problemRalf Baechle
Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler and gcc 3.4.6 for the mips-linux target results in the following build error: $ make malta_defconfig $ make cc1: error: unrecognized command line option "-fno-stack-protector" scripts/kconfig/conf -s arch/mips/Kconfig cc1: error: unrecognized command line option "-fno-stack-protector" The arch Makefile is included too late so the host compiler is feature tested, not the crosscompiler as intended and thus the Makefile applies adds -fno-stack-protector to crosscompiler's flags which fails for gcc 3.4.6. The bug was introduced by e06b8b98da071f7dd78fb7822991694288047df0 in 2.6.25; 35bb5b1e0e84cfa1a8906f7e6a77f391ff315791 did add more flags testing before the arch Makefile inclusion.

The ad7418 driver is only used on embedded platforms where i2c devices can easily be declared in platform code. Thus a new-style i2c driver makes perfect sense. This lets us get rid of quirky detection code (these chips have no identification registers) and shrinks the binary driver size by 38%.
