Driver for the CompactFlash slot on the PA Semi Electra eval board. It's a simple device sitting on localbus, with interrupts and detect/voltage control over GPIO. The driver is implemented as an of_platform driver, and adds localbus as a bus being probed by the of_platform framework.

Update dump_task_altivec() (which has so far never been put to use) so that it dumps the Altivec/VMX registers (VR[0] - VR[31], VSCR and VRSAVE) in the same format as the ptrace get_vrregs(), and add the appropriate glue typedef and #defines to make it work. A new note type of NT_PPC_VMX was chosen to be 0x100 (arbitrarily) because it allows the low range values to be used for more generic purposes and 0x100 seems an adequate starting point for PowerPC extensions.

The current DWARF info for CR are incorrect, causing the gcc unwinder to go to lunch if we take a segfault in the vdso. This fixes it. Problem identified by Andrew Haley, and fix provided by Jakub Jelinek (thanks !). Unfortunately, a bug in gcc cause it to not quite work either, but that is being fixed separately with something around the lines of: linux-unwind.h: fs->regs.reg[R_CR2].loc.offset = (long) ®s->ccr - new_cfa; + /* CR? regs are just 32-bit and PPC is big-endian. */ + fs->regs.reg[R_CR2].loc.offset += sizeof (long) - 4; (According to Jakub) Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NPaul Mackerras <paulus@samba.org>

PA6T has a bug where the slbie instruction does not honor the large segment bit. As a result, we have to always use slbia when switching context. We don't have to worry about changing the slbie's during fault processing, since they should never be replacing one VSID with another using the same ESID. I.e. there's no risk for inserting duplicate entries due to a failed slbie of the old entry. So as long as we clear it out on context switch we should be fine.

After 6 years the ppc64 kernel still thinks its important to tell me my cache line size is 0x80 bytes. I think most people who care know that by now. The rest probably cant even understand the hex output. Since we might have misconfigured firmware or cpus that have a linesize that isnt 128 bytes, I still print it out for those cases. If people would prefer to remove it completely, lets do it. Also for lpar remove the htab_address printout since its not used.

When checking out the new NO_HZ support in powerpc, I noticed we never slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.

The devtree root is now searched for devices matching a built-in whitelist during boot, so these devices appear on the bus from the beginning. It is still possible to manually add/remove devices to/from the bus by using the probe/remove sysfs interface.

Remove old code that will be replaced by rewritten and shorter functions in the next patch.

Extract generic of_device allocation code from of_platform_device_create() and move it into of_device.[ch], called of_device_alloc(). Also, there's now of_device_free() which puts the device node.

This patch adds support for the core of the BestComm API for the Freescale MPC5200(b). The BestComm engine is a microcode-controlled / tasks-based DMA used by several of the onchip devices. Setting up the tasks / memory allocation and all common low level functions are handled by this patch. The specifics details of each tasks and their microcode are split-out in separate patches. This is not the official API, but a much cleaner one. (hopefully) Signed-off-by: NSylvain Munaut <tnt@246tNt.com> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

Introduce architecture dependent kretprobe blacklists to prohibit users from inserting return probes on the function in which kprobes can be inserted but kretprobes can not.

Now, arch dependent code around CONFIG_MEMORY_HOTREMOVE is a mess. This patch cleans up them. This is against 2.6.23-rc6-mm1. - fix compile failure on ia64/ CONFIG_MEMORY_HOTPLUG && !CONFIG_MEMORY_HOTREMOVE case. - For !CONFIG_MEMORY_HOTREMOVE, add generic no-op remove_memory(), which returns -EINVAL. - removed remove_pages() only used in powerpc. - removed no-op remove_memory() in i386, sh, sparc64, x86_64. - only powerpc returns -ENOSYS at memory hot remove(no-op). changes it to return -EINVAL.
