2008-10-22powerpc: Move memory size print into common show_cpuinfo for 32-bitBecky Bruce
Most of the platforms were printing the size of the memory in their show_cpuinfo implementations. This moves that to the common show_cpuinfo, so that all 32-bit platforms will now print the size of memory. I also update the code to deal with the fact that total_memory is now a phys_addr_t.

2008-10-21powerpc: Revert CHRP boot wrapper to real-base = 12MB on 32-bitPaul Mackerras
Commit 9b09c6d909dfd8de96b99b9b9c808b94b0a71614 ("powerpc: Change the default link address for pSeries zImage kernels") changed the real-base value in the CHRP note added by addnote to the zImage from 12MB to 32MB. It turns out that this causes unnecessary extra reboots on old 32-bit CHRP machines. This therefore adds a -r flag to addnote to allow us to specify what real-base value it should put in the CHRP note, and adjusts the wrapper script to pass -r c00000 to addnote when making a zImage for a CHRP machine. Also, CHRP machines ignore the RPA note, so we don't need to arrange for it to be the same as the kernel's.

2008-10-21powerpc: Always trim numa memory to lmb_end_of_DRAM()Milton Miller
numa_enforce_memory_limit tried to be smart and only call lmb_end_of_DRAM when a memory limit was set via mem= on the command line. However, the early boot code will also limit memory added to the lmb system when iommu=off is specified. When this happens, the page allocator is given pages not in the linear mapping and this results in a fatal data reference to the unmapped page.

2008-10-21powerpc: Find and destroy possible stale kernel added propertiesMilton Miller
64 bit powerpc requires the kexec user space tools avoid overwriting the static kernel image and translation hash table when choosing where to put memory image data because it copies the data into place using the kernels virtual memory system. Kexec userspace determines these and other areas blocked by reading properties the kernel adds, but does not filter these properties when creating the device tree for the next kernel. When the second kernel tries to add its values for these properties, the export via /proc/device-tree is hidden by the pre-existing but stale values from the flat tree. Kexec userspace reads the old property, allocates the new kernel at the old kernel's end, and gets rejected by the overlap check. Search and remove these stale properties before adding the new values. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2008-10-21powerpc/oprofile: Fix mutex locking for cell spu-oprofileCarl Love
The issue is the SPU code is not holding the kernel mutex lock while adding samples to the kernel buffer. This patch creates per SPU buffers to hold the data. Data is added to the buffers from in interrupt context. The data is periodically pushed to the kernel buffer via a new Oprofile function oprofile_put_buff(). The oprofile_put_buff() function is called via a work queue enabling the funtion to acquire the mutex lock. The existing user controls for adjusting the per CPU buffer size is used to control the size of the per SPU buffers. Similarly, overflows of the SPU buffers are reported by incrementing the per CPU buffer stats. This eliminates the need to have architecture specific controls for the per SPU buffers which is not acceptable to the OProfile user tool maintainer. The export of the oprofile add_event_entry() is removed as it is no longer needed given this patch. Note, this patch has not addressed the issue of indexing arrays by the spu number. This still needs to be fixed as the spu numbering is not guarenteed to be 0 to max_num_spus-1.

2008-10-21powerpc/boot: Compare _start against ei.loadsize instead ei.memsizeSebastian Siewior
If the vmlinux binary in memory is larger than 4 MiB than it collides with the initial boot code which is linked at 4 MiB in case of cuBoot. If the the uncompressed image size (on disk size) is less than 4 MiB then it would fit. The difference between those two sizes is the bss section. In cuBoot we have the dtb embedded right after the data section so it is very likely that the reset of the bss section (in kernel's start up code) will overwrite the dtb blob. Therefore we reallocate the dtb. Something similar is allready done to the initrd.

2008-10-21powerpc/spufs: Don't spu_acquire_saved unnecessarily in regs readJeremy Kerr
With most file readers (eg cat, dd), reading a context's regs file will result in two reads: the first to read the data, and the second to return EOF. Because each read performs a spu_acquire_saved, we end up descheduling and re-scheduling the context twice. This change does a simple check to see if we'd return EOF before calling spu_acquire_saved(), saving the extra schedule operation. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2008-10-21powerpc/spufs: Don't require full buffer in switch_log readJeremy Kerr
Currently, read() on the sputrace log will block until the read buffer is full. This makes it difficult to retrieve the end of the buffer, as the user will need to read with the right-sized buffer. In a similar method as 91553a1b5e0df006a3573a88d98ee7cd48a3818a, this change makes the switch_log return if there has already been data read. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2008-10-21powerpc/spufs: Use state_mutex for switch_log locking, and prevent multiple ↵Jeremy Kerr
openers Currently, we use ctx->mapping_lock and ctx->switch_log->lock for the context switch log. The mapping lock only prevents concurrent open()s, so we require the switch_lock->lock for reads. Since writes to the switch log buffer occur on context switches, we're better off synchronising with the state_mutex, which is held during a switch. Since we're serialised througout the buffer reads and writes, we can use the state mutex to protect open and release too, and can now kfree() the log buffer on release. This allows us to perform the switch log notify without taking any extra locks. Because the buffer is only present while the file is open, we can use it to prevent multiple simultaneous openers. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2008-10-21powerpc/spufs: sputrace: Don't block until the read buffer is fullJeremy Kerr
Currently, read() on the sputrace buffer will only return data when the user buffer is exhausted. This may mean that we never see the end of the event log, unless we read() with exactly the right-sized buffer. This change makes sputrace_read not block if we have data ready to return. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2008-10-21powerpc/spufs: sputrace: Only enable logging on open(), prevent multiple openersJeremy Kerr
Currently, sputrace will start logging to the event buffer before the log buffer has been open()ed. This results in a heap of "lost samples" warnings if the sputrace file hasn't yet been opened. Since the buffer is reset on open() anyway, there's no need to enable logging when no-one has opened the log. Because open clears the log, make it return EBUSY for mutliple open calls.

2008-10-20kdump: make elfcorehdr_addr independent of CONFIG_PROC_VMCOREVivek Goyal
o elfcorehdr_addr is used by not only the code under CONFIG_PROC_VMCORE but also by the code which is not inside CONFIG_PROC_VMCORE. For example, is_kdump_kernel() is used by powerpc code to determine if kernel is booting after a panic then use previous kernel's TCE table. So even if CONFIG_PROC_VMCORE is not set in second kernel, one should be able to correctly determine that we are booting after a panic and setup calgary iommu accordingly. o So remove the assumption that elfcorehdr_addr is under CONFIG_PROC_VMCORE. o Move definition of elfcorehdr_addr to arch dependent crash files. (Unfortunately crash dump does not have an arch independent file otherwise that would have been the best place). o kexec.c is not the right place as one can Have CRASH_DUMP enabled in second kernel without KEXEC being enabled. o I don't see sh setup code parsing the command line for elfcorehdr_addr. I am wondering how does vmcore interface work on sh. Anyway, I am atleast defining elfcoredhr_addr so that compilation is not broken on sh.

2008-10-20container freezer: implement freezer cgroup subsystemMatt Helsley
This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.
