powerpc/ps3: Add dma_mask to ps3_dma_region

2021-07-20T14:22:41+00:00

[ Upstream commit 9733862e50fdba55e7f1554e4286fcc5302ff28e ] Commit f959dcd6ddfd29235030e8026471ac1b022ad2b0 (dma-direct: Fix potential NULL pointer dereference) added a null check on the dma_mask pointer of the kernel's device structure. Add a dma_mask variable to the ps3_dma_region structure and set the device structure's dma_mask pointer to point to this new variable. Fixes runtime errors like these: # WARNING: Fixes tag on line 10 doesn't match correct format # WARNING: Fixes tag on line 10 doesn't match correct format ps3_system_bus_match:349: dev=8.0(sb_01), drv=8.0(ps3flash): match WARNING: CPU: 0 PID: 1 at kernel/dma/mapping.c:151 .dma_map_page_attrs+0x34/0x1e0 ps3flash sb_01: ps3stor_setup:193: map DMA region failed Signed-off-by: Geoff Levand Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/562d0c9ea0100a30c3b186bcc7adb34b0bbd2cd7.1622746428.git.geoff@infradead.org Signed-off-by: Sasha Levin

powerpc: Delete non-required instances of include

2014-01-15T02:46:44+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. The one instance where we add an include for init.h covers off a case where that file was implicitly getting it from another header which itself didn't need it.

powerpc/ps3: Add macro PS3_VERBOSE_RESULT

2013-02-15T05:54:39+00:00

To allow more control of the verbosity of ps3_result() add a check for the preprocessor macro PS3_VERBOSE_RESULT that builds a verbose verion of the ps3_result() routine. Signed-off-by: Geoff Levand Signed-off-by: Benjamin Herrenschmidt

ps3: Replace direct file operations by callback

2009-06-15T06:47:26+00:00

Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example. Replace the file operations by callbacks, registered by the ps3flash driver. Signed-off-by: Geert Uytterhoeven Cc: Geoff Levand Acked-by: Geoff Levand Signed-off-by: Benjamin Herrenschmidt

powerpc/ps3: Use dma_addr_t down through the stack

2009-01-16T05:15:11+00:00

Push the dma_addr_t type usage all the way down to where the actual values are manipulated. Now that u64 is "unsigned long long", this removes warnings like: arch/powerpc/platforms/ps3/system-bus.c:532: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type arch/powerpc/platforms/ps3/system-bus.c:649: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type Signed-off-by: Stephen Rothwell Acked-by: Geoff Levand Signed-off-by: Benjamin Herrenschmidt
