2011-08-04Do 'shm_init_ns()' in an early pure_initcallLinus Torvalds1-1/+8
This isn't really critical any more, since other patches (commit 298507d4d2cf: "shm: optimize exit_shm()") have caused us to not actually need to touch the rw_mutex unless there are actual shm segments associated with the namespace, but we really should do tne shm_init_ns() earlier than we do now. This, together with commit 288d5abec831 ("Boot up with usermodehelper disabled") will mean that we really do initialize the initial ipc namespace data structure before we run any tasks.

2011-08-05powerpc/pseries: Fix kexec on recent firmware versionsAnton Blanchard3-3/+14
Recent versions of firmware will fail to unmap the virtual processor area if we have a dispatch trace log registered. This causes kexec to fail. If a trace log is registered this patch unregisters it before the SLB shadow and virtual processor areas, fixing the problem. The address argument is ignored by firmware on unregister so we may as well remove it.

2011-08-05powerpc: Make KVM_GUEST default to nAnton Blanchard1-1/+1
KVM_GUEST adds a 1 MB array to the kernel (kvm_tmp) which grew my kernel enough to cause it to fail to boot. Dynamically allocating or reducing the size of this array is a good idea, but in the meantime I think it makes sense to make KVM_GUEST default to n in order to minimise surprises.

2011-08-05powerpc: Move kdump default base address to half RMO size on 64bitAnton Blanchard2-13/+7
We are seeing boot failures on some very large boxes even with commit b5416ca9f824 (powerpc: Move kdump default base address to 64MB on 64bit). This patch halves the RMO so both kernels get about the same amount of RMO memory. On large machines this region will be at least 256MB, so each kernel will get 128MB. We cap it at 256MB (small SLB size) since some early allocations need to be in the bolted SLB region. We could relax this on machines with 1TB SLBs in a future patch.

To handle the page fault the mmap_sem is needed, but it is currently held by setup_arg_pages. (setup_arg_pages calls shift_arg_pages with the mmap_sem held. shift_arg_pages then calls move_page_tables which has a cond_resched at the top of its for loop - hitting that cond_resched is what caused the context switch.) This is an extension of Anton's proposed patch: https://lkml.org/lkml/2011/7/24/151 adding case for 32-bit ppc. Tested on the system that first generated the panic and then again with latest kernel using a PPC VM. I am not able to test the 64-bit path - I do not have H/W for it and 64-bit PPC VMs (qemu on Intel) is horribly slow.

2011-08-05powerpc: Jump label misalignment causes oops at bootAnton Blanchard1-2/+0
I hit an oops at boot on the first instruction of timer_cpu_notify: NIP [c000000000722f88] .timer_cpu_notify+0x0/0x388 The code should look like: c000000000722f78: eb e9 00 30 ld r31,48(r9) c000000000722f7c: 2f bf 00 00 cmpdi cr7,r31,0 c000000000722f80: 40 9e ff 44 bne+ cr7,c000000000722ec4 c000000000722f84: 4b ff ff 74 b c000000000722ef8 c000000000722f88 <.timer_cpu_notify>: c000000000722f88: 7c 08 02 a6 mflr r0 c000000000722f8c: 2f a4 00 07 cmpdi cr7,r4,7 c000000000722f90: fb c1 ff f0 std r30,-16(r1) c000000000722f94: fb 61 ff d8 std r27,-40(r1) But the oops output shows: eb61ffd8 eb81ffe0 eba1ffe8 ebc1fff0 7c0803a6 ebe1fff8 4e800020 00000000 ebe90030 c0000000 00ad0a28 00000000 2fa40007 fbc1fff0 fb61ffd8 So we scribbled over our instructions with c000000000ad0a28, which is an address inside the jump_table ELF section. It turns out the jump_table section is only aligned to 8 bytes but we are aligning our entries within the section to 16 bytes. This means our entries are offset from the table: c000000000acd4a8 <__start___jump_table>: ... c000000000ad0a10: c0 00 00 00 lfs f0,0(0) c000000000ad0a14: 00 70 cd 5c .long 0x70cd5c c000000000ad0a18: c0 00 00 00 lfs f0,0(0) c000000000ad0a1c: 00 70 cd 90 .long 0x70cd90 c000000000ad0a20: c0 00 00 00 lfs f0,0(0) c000000000ad0a24: 00 ac a4 20 .long 0xaca420 And the jump table sort code gets very confused and writes into the wrong spot.

2011-08-05powerpc: Fix device tree claim codeAnton Blanchard1-3/+3
I have a box that fails in OF during boot with: DEFAULT CATCH!, exception-handler=fff00400 at %SRR0: 49424d2c4c6f6768 %SRR1: 800000004000b002 ie "IBM,Logh". OF got corrupted with a device tree string. Looking at make_room and alloc_up, we claim the first chunk (1 MB) but we never claim any more. mem_end is always set to alloc_top which is the top of our available address space, guaranteeing we will never call alloc_up and claim more memory. Also alloc_up wasn't setting alloc_bottom to the bottom of the available address space. This doesn't help the box to boot, but we at least fail with an obvious error. We could relocate the device tree in a future patch. Signed-off-by: Anton Blanchard <[email protected]> Cc: <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-08-05powerpc: Return the_cpu_ spec from identify_cpuScott Wood1-5/+6
Commit af9eef3c7b1ed004c378c89b87642f4937337d50 caused cpu_setup to see the_cpu_spec, rather than the source struct. However, on 32-bit, the return value of identify_cpu was being used for feature fixups, and identify_cpu was returning the source struct. So if cpu_setup patches the feature bits, the update won't affect the fixups. Signed-off-by: Scott Wood <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-08-05powerpc: mtspr/mtmsr should take an unsigned longScott Wood1-2/+5
Add a cast in case the caller passes in a different type, as it would if mtspr/mtmsr were functions. Previously, if a 64-bit type was passed in on 32-bit, GCC would bind the constraint to a pair of registers, and would substitute the first register in the pair in the asm code. This corresponds to the upper half of the 64-bit register, which is generally not the desired behavior.

2011-08-04exofs: BUG: Avoid sbi reallocBoaz Harrosh2-24/+30
Since the beginning we realloced the sbi structure when a bigger then one device table was specified. (I know that was really stupid). Then much later when "register bdi" was added (By Jens) it was registering the pointer to sbi->bdi before the realloc. We never saw this problem because up till now the realloc did not do anything since the device table was small enough to fit in the original allocation. But once we starting testing with large device tables (Bigger then 28) we noticed the crash of writeback operating on a deallocated pointer. * Avoid the all mess by allocating the device-table as a second array and get rid of the variable-sized structure and the rest of this mess. * Take the chance to clean near by structures and comments. * Add a needed dprint on startup to indicate the loaded layout. * Also move the bdi registration to the very end because it will only fail in a low memory, which will probably fail before hand. There are many more likely causes to not load before that. This way the error handling is made simpler. (Just doing this would be enough to fix the BUG) Signed-off-by: Boaz Harrosh <[email protected]>

2011-08-04drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC ↵Thomas Reim4-12/+80
Lines (here: Asus M2A-VM HDMI) Some integrated ATI Radeon chipset implementations with add-on HDMI card (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even when the add-on card is not plugged in or HDMI is disabled in BIOS setup. In this case, drm_get_edid() and drm_edid_block_valid() periodically dump data and kernel errors into system log files and onto terminals. For these connectors DDC probing is extended by a check for a correct EDID header. Only in case a valid EDID header is also found, the (HDMI or DVI) connector will be used by the Radeon driver. This prevents the kernel driver from useless flooding of logs and terminal sessions with EDID dumps and error messages. This patch adds a flag 'requires_extended_probe' to the radeon_connector structure. In function radeon_connector_needs_extended_probe() this flag can be set on a chipset family/vendor/connector type specific basis. In addition, function radeon_ddc_probe() has been adapted to perform extended DDC probing if required by the connector's flag. Requires function drm_edid_header_is_valid() in DRM module provided by [PATCH] drm: Separate EDID Header Check from EDID Block Check.

2011-08-04drm: Separate EDID Header Check from EDID Block CheckThomas Reim2-6/+19
Provides function drm_edid_header_is_valid() for EDID header check and replaces EDID header check part of function drm_edid_block_valid() by a call of drm_edid_header_is_valid(). This is a prerequisite to extend DDC probing, e. g. in function radeon_ddc_probe() for Radeon devices, by a central EDID header check.

2011-08-04drm: Add NULL check about irq functionsJoonyoung Shim1-8/+15
The struct drm_driver has some function pointers for irq. They are gpu specific and some functions aren't essential things. This can prevents creation of unnecessary dummy function for irq.
