2010-02-10powerpc/44x: Add MTD support (NOR FLASH) to Katmai dtsStefan Roese
This patch adds NOR FLASH MTD support to the Katmai (440SPe) dts file. For this the OPB ranges address is mapped differently (base 0x00000000 -> 0xe0000000). This results in the address being identical to the lower 32bit of its physical address. This is needed for the MTD mapping to work correctly, since U-Boot will insert the physical addresses of the EBC chip selects into the EBC ranges property. This is the way its done in most other 4xx dts files as well. Additionally with a small whitespace cleanup.

2010-02-04powerpc/pseries: Pass more accurate number of supported cores to firmwareBenjamin Herrenschmidt
Updated variant of a patch by Joel Schopp. The field containing the number of supported cores which we pass to firmware via the ibm,client-architecture call was set by a previous patch statically as high as is possible (NR_CPUS). However, that value isn't quite right for a system that supports multiple threads per core, thus permitting the firmware to assign more cores to a Linux partition than it can really cope with. This patch improves it by using the device-tree to determine the number of threads supported by the processors in order to adjust the value passed to firmware.

2010-02-03powerpc: Add static fields to ibm,client-architecture calljschopp@austin.ibm.com
This patch adds 2 fields to the ibm_architecture_vec array. The first of these fields indicates the number of cores which Linux can boot. It does not account for SMT, so it may result in cpus assigned to Linux which cannot be booted. A second patch follows that dynamically updates this for SMT. The second field just indicates that our OS is Linux, and not another OS. The system may or may not use this hint to performance tune settings for Linux.

2010-02-03powerpc: Increase NR_IRQS Kconfig maximum to 32768Anton Blanchard
With dynamic irq descriptors the overhead of a large NR_IRQS is much lower than it used to be. With more MSI-X capable adapters and drivers exploiting multiple vectors we may as well allow the user to increase it beyond the current maximum of 512. 32768 seems large enough that we'd never have to bump it again (although I bet my prediction is horribly wrong). It boot tests OK and the vmlinux footprint increase is only around 500kB due to: struct irq_map_entry irq_map[NR_IRQS]; We format /proc/interrupts correctly with the previous changes: CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 286: 0 0 0 0 0 0 516: 0 0 0 0 0 0 16689: 1833 0 0 0 0 0 17157: 0 0 0 0 0 0 17158: 319 0 0 0 0 0 25092: 0 0 0 0 0 0 Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-02-03powerpc/85xx: Fix SMP when "cpu-release-addr" is in lowmemPeter Tyser
Recent U-Boot commit 5ccd29c3679b3669b0bde5c501c1aa0f325a7acb caused the "cpu-release-addr" device tree property to contain the physical RAM location that secondary cores were spinning at. Previously, the "cpu-release-addr" property contained a value referencing the boot page translation address range of 0xfffffxxx, which then indirectly accessed RAM. The "cpu-release-addr" is currently ioremapped and the secondary cores kicked. However, due to the recent change in "cpu-release-addr", it sometimes points to a memory location in low memory that cannot be ioremapped. For example on a P2020-based board with 512MB of RAM the following error occurs on bootup: <...> mpic: requesting IPIs ... __ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0 Unable to handle kernel paging request for data at address 0x00000014 Faulting instruction address: 0xc05df9b0 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 P2020 RDB Modules linked in: <... eventual kernel panic> Adding logic to conditionally ioremap or access memory directly resolves the issue.

2010-02-01MIPS: Alchemy: Fix dbdma ring destruction memory debugcheck.Manuel Lauss
DBDMA descriptors need to be located at 32-byte aligned addresses; however kmalloc in conjunction with the SLAB allocator and CONFIG_DEBUG_SLUB enabled doesn't deliver any. The dbdma code works around that by allocating a larger area and realigning the start address within it. When freeing a channel however this adjustment is not taken into account which results in an oops: Kernel bug detected[#1]: [...] Call Trace: [<80186010>] cache_free_debugcheck+0x284/0x318 [<801869d8>] kfree+0xe8/0x2a0 [<8010b31c>] au1xxx_dbdma_chan_free+0x2c/0x7c [<80388dc8>] au1x_pcm_dbdma_free+0x34/0x4c [<80388fa8>] au1xpsc_pcm_close+0x28/0x38 [<80383cb8>] soc_codec_close+0x14c/0x1cc [<8036dbb4>] snd_pcm_release_substream+0x60/0xac [<8036dc40>] snd_pcm_release+0x40/0xa0 [<8018c7a8>] __fput+0x11c/0x228 [<80188f60>] filp_close+0x7c/0x98 [<80189018>] sys_close+0x9c/0xe4 [<801022a0>] stack_done+0x20/0x3c Fix this by recording the address delivered by kmalloc() and using it as parameter to kfree(). This fix is only necessary with the SLAB allocator and CONFIG_DEBUG_SLAB enabled; non-debug SLAB, SLUB do return nicely aligned addresses, debug-enabled SLUB currently panics early in the boot process.

2010-01-30perf, hw_breakpoint, kgdb: Do not take mutex for kernel debuggerJason Wessel
This patch fixes the regression in functionality where the kernel debugger and the perf API do not nicely share hw breakpoint reservations. The kernel debugger cannot use any mutex_lock() calls because it can start the kernel running from an invalid context. A mutex free version of the reservation API needed to get created for the kernel debugger to safely update hw breakpoint reservations. The possibility for a breakpoint reservation to be concurrently processed at the time that kgdb interrupts the system is improbable. Should this corner case occur the end user is warned, and the kernel debugger will prohibit updating the hardware breakpoint reservations. Any time the kernel debugger reserves a hardware breakpoint it will be a system wide reservation.

2010-01-30x86, hw_breakpoints, kgdb: Fix kgdb to use hw_breakpoint APIJason Wessel
In the 2.6.33 kernel, the hw_breakpoint API is now used for the performance event counters. The hw_breakpoint_handler() now consumes the hw breakpoints that were previously set by kgdb arch specific code. In order for kgdb to work in conjunction with this core API change, kgdb must use some of the low level functions of the hw_breakpoint API to install, uninstall, and deal with hw breakpoint reservations. The kgdb core required a change to call kgdb_disable_hw_debug anytime a slave cpu enters kgdb_wait() in order to keep all the hw breakpoints in sync as well as to prevent hitting a hw breakpoint while kgdb is active. During the architecture specific initialization of kgdb, it will pre-allocate 4 disabled (struct perf event **) structures. Kgdb will use these to manage the capabilities for the 4 hw breakpoint registers, per cpu. Right now the hw_breakpoint API does not have a way to ask how many breakpoints are available, on each CPU so it is possible that the install of a breakpoint might fail when kgdb restores the system to the run state. The intent of this patch is to first get the basic functionality of hw breakpoints working and leave it to the person debugging the kernel to understand what hw breakpoints are in use and what restrictions have been imposed as a result. Breakpoint constraints will be dealt with in a future patch. While atomic, the x86 specific kgdb code will call arch_uninstall_hw_breakpoint() and arch_install_hw_breakpoint() to manage the cpu specific hw breakpoints. The net result of these changes allow kgdb to use the same pool of hw_breakpoints that are used by the perf event API, but neither knows about future reservations for the available hw breakpoint slots.

2010-01-29Split 'flush_old_exec' into two functionsLinus Torvalds
'flush_old_exec()' is the point of no return when doing an execve(), and it is pretty badly misnamed. It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
