drivercore: revert addition of of_match to struct device

2011-05-18T18:32:23+00:00

Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely

sparc32: Fixed unaligned memory copying in function __csum_partial_copy_sparc_generic

2011-05-12T04:35:04+00:00

When we are in the label cc_dword_align, registers %o0 and %o1 have the same last 2 bits, but it's not guaranteed one of them is zero. So we can get unaligned memory access in label ccte. Example of parameters which lead to this: %o0=0x7ff183e9, %o1=0x8e709e7d, %g1=3 With the parameters I had a memory corruption, when the additional 5 bytes were rewritten. This patch corrects the error. One comment to the patch. We don't care about the third bit in %o1, because cc_end_cruft stores word or less. Signed-off-by: Tkhai Kirill Signed-off-by: David S.

sparc32: fix sparcstation 5 boot

2011-04-21T23:35:46+00:00

The sparcstation 5 I have available has no MID property for the CPU. This resulted in a panic when booting a SMP kernel on this box. The assigned field in cpu_data is never used, so if we fail to read the MID property then inform user and continue booting. Signed-off-by: Sam Ravnborg Signed-off-by: David S. Miller

sparc32: fix section mismatch warnings in apc, pmc and time_32

2011-04-21T22:37:20+00:00

In all cases there were a struct of_device_id variable defined __initdata. But it was referenced from struct platform_driver.of_match_table which is not guaranteed to be used during init only. So drop the __initdata annotation. This fixes following warnings: WARNING: arch/sparc/kernel/built-in.o(.data+0x810): Section mismatch in reference from the variable clock_driver to the variable .init.data:clock_match The variable clock_driver references the variable __initdata clock_match If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/sparc/kernel/built-in.o(.data+0xcec): Section mismatch in reference from the variable apc_driver to the variable .init.data:apc_match The variable apc_driver references the variable __initdata apc_match If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console WARNING: arch/sparc/kernel/built-in.o(.data+0xd60): Section mismatch in reference from the variable pmc_driver to the variable .init.data:pmc_match The variable pmc_driver references the variable __initdata pmc_match If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console Signed-off-by: Sam Ravnborg Signed-off-by: David S.

sparc32: Pass task_struct to schedule_tail() in ret_from_fork

2011-03-31T07:52:38+00:00

We have to pass task_struct of previous process to function schedule_tail(). Currently in ret_from_fork previous thread_info is passed: switch_to: mov %g6, %g3 /* previous thread_info in g6 */ ret_from_fork: call schedule_tail mov %g3, %o0 /* previous thread_info is passed */ void schedule_tail(struct task_struct *prev); Signed-off-by: Tkhai Kirill Signed-off-by: David S.

sparc64: Fix section mis-match errors.

2011-03-31T00:37:56+00:00

Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under arch/sparc during a 64-bit defconfig build. They fall into two categorites: 1) of_device_id is marked as __initdata, and we can never do this since these objects sit in the device core data structures way past boot. So even if a driver will never be reloaded, we have to keep the device ID table around. Mark such cases const instead. 2) The bootmem alloc/free handling code in mdesc.c was not fully marked __init as it should be, thus generating a reference to free_bootmem_late() (which is __init) from non-__init code.
