io_mapping_create_wc should take a resource_size_t parameter in place of unsigned long. With unsigned long, there will be no way to map greater than 4GB address in i386/32 bit. On x86, greater than 4GB addresses cannot be mapped on i386 without PAE. Return error for such a case. Patch also adds a structure for io_mapping, that saves the base, size and type on HAVE_ATOMIC_IOMAP archs, that can be used to verify the offset on io_mapping_map calls.

Impact: fix unexpected behaviour when pattern number is out of range Current implementation provides 4 patterns for memtest. The code doesn't check whether the memtest parameter value exceeds the maximum pattern number. Instead the memtest code pretends to test with non-existing patterns, e.g. when booting with memtest=10 I've observed the following ... early_memtest: pattern num 10 0000001000 - 0000006000 pattern 0 ... 0000001000 - 0000006000 pattern 1 ... 0000001000 - 0000006000 pattern 2 ... 0000001000 - 0000006000 pattern 3 ... 0000001000 - 0000006000 pattern 4 ... 0000001000 - 0000006000 pattern 5 ... 0000001000 - 0000006000 pattern 6 ... 0000001000 - 0000006000 pattern 7 ... 0000001000 - 0000006000 pattern 8 ... 0000001000 - 0000006000 pattern 9 ... But in fact Linux didn't test anything for patterns > 4 as the default case in memtest() is to leave the function. I suggest to use the memtest parameter as the number of tests to be performed and to re-iterate over all existing patterns.

Impact: make more types of copies non-temporal This change makes the following simple fix: 30d697fa: x86: fix performance regression in write() syscall A bit more sophisticated: we check the 'total' number of bytes written to decide whether to copy in a cached or a non-temporal way. This will for example cause the tail (modulo 4096 bytes) chunk of a large write() to be non-temporal too - not just the page-sized chunks.

Impact: cleanup, enable future change Add a 'total bytes copied' parameter to __copy_from_user_*nocache(), and update all the callsites. The parameter is not used yet - architecture code can use it to more intelligently decide whether the copy should be cached or non-temporal.

The ones which go only into struct genapic are de-inlined by compiler anyway, so remove the inline specifier from them. Afterwards, remove summit_setup_portio_remap completely as it is unused. Remove inline also from summit_cpu_mask_to_apicid, since it's not worth it (it is used in struct genapic too).

This was changed to a physmap_t giving a clashing symbol redefinition, but actually using a physmap_t consumes rather a lot of space on x86, so stick with a private copy renamed with a voyager_ prefix and made static.

i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers should use set this value in terms of HZ.

The unit in which user-space can set the bus timeout value is jiffies for historical reasons (back when HZ was always 100.) This is however not good because user-space doesn't know how long a jiffy lasts. The timeout value should instead be set in a fixed time unit. Given the original value of HZ, this unit should be 10 ms, for compatibility. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Wolfram Sang <w.sang@pengutronix.de>

With a postfix decrement these timeouts reach -1 rather than 0, but after the loop it is tested whether they have become 0. As pointed out by Jean Delvare, the condition we are waiting for should also be tested before the timeout. With the current order, you could exit with a timeout error while the job is actually done.
