2009-12-06ARM: gta02: Add gpio bank B quirk for hardware revision 5 and earlierLars-Peter Clausen
On hardware revision 5 and earlier the leds found on the gta02 are missing a resistor and reading their gpio pin status will always return 0. So we have to shadow the led states in software. This is done by "hijacking" the gpio accessor functions for bank B. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-02VIDEO: Correct use of request_region/request_mem_regionJulia Lawall
request_region should be used with release_region, not request_mem_region. Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c, the problem is actually the other way around; request_mem_region should be used instead of request_region. The semantic patch that finds/fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r1@ expression start; @@ request_region(start,...) @b1@ expression r1.start; @@ request_mem_region(start,...) @depends on !b1@ expression r1.start; expression E; @@ - release_mem_region + release_region (start,E) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-12-02modules: don't export section names of empty sections via sysfsHelge Deller
On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.

2009-12-02[ARM] pxamci: call mmc_remove_host() before freeing resourcesDaniel Mack
mmc_remove_host() will cause the mmc core to switch off the bus power by eventually calling pxamci_set_ios(). This function uses the regulator or the GPIO which have been freed already. This causes the following Oops on module unload.

2009-12-01rtc-x1205: reset clock to sane state after power failureJohannes Weiner
When detecting power failure, the probe function would reset the clock time to defined state.

Change the power-failure fixup code to do a full setting of rtc_time, including a valid date.

2009-12-01rtc-x1205: fix rtc_time to y2k register value conversionJohannes Weiner
The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's tm_year is in years since 1900. The function translating rtc_time to register values assumes tm_year to be years since first christmas, though, and we end up storing 0 or 1 in the CCR_Y2K register, which the hardware does not refuse to do. A subsequent probing of the clock fails due to the invalid value range in the register, though. [ And if it didn't, reading the clock would yield a bogus year because the function translating registers to tm_year is assuming a register value of 19 or 20. ] This fixes the conversion from years since 1900 in tm_year to the corresponding CCR_Y2K value of 19 or 20.

2009-12-01MIPS: Loongson: Switch from flatmem to sparsememWu Zhangjin
With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. The config help of sparsemem says: "This option provides some potential performance benefits, along with decreased code complexity." So to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.

2009-12-01MIPS: Loongson: Disallow 4kB pagesWu Zhangjin
Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.
