Commit 1e434f93 (OMAPFB: remove early mem alloc from old omapfb) deleted the support for early fbmem allocation from the platform code, but some code still remains in the driver side. Delete this code now, as it repotedly causes build issues on !MMU. The patch was tested on Amstrad E3 and Nokia 770 and framebuffer functionality is not affected. Signed-off-by:

The error message would try to dereference the pointer that just has been tested to be NULL. As those messages don't really add any value without the info that the np could provide, just remove them. Signed-off-by:

All drivers under menu EXYNOS_VIDEO depend on either ARCH_S5PV210 or ARCH_EXYNOS, so add these as dependencies to the menu itself. This avoids presenting an empty and useless menu on other architectures. Then drivers under the menu only need a dependency if they depend on one of the supported architectures specifically.

The frame buffer core may be a loadable module, and in this case, the nuc900 driver cannot be built-in. Turning it into a tristate option lets Kconfig work out the dependency and avoid broken builds. Signed-off-by:

The mbx framebuffer debugfs support apparently hasn't been able to build for a long time, at least since 2006 when the u.generic_ip field in the inode was removed. This fixes the obvious bug, and also makes it possible to build the driver as a module when debugfs support is enabled, by simply including the C file. It's ugly, but it won't make the driver any worse than it already is, and doesn't require a more invasive change that might break it further. Signed-off-by:

The framebuffer layer can be a loadable module, which forces omapfb to be a module as well. However, this breaks the lcd drivers, which are linked into the omapfb driver but each have their own module_init() function. To solve this, we split out the lcd drivers into separate modules and export omapfb_register_panel, which is the only interface required between the main omapfb driver and the lcd panel drivers. We also have to introduce a new Kconfig symbol for H3, since that lcd driver has a dependency on TPS65010, which we can express better in Kconfig than Makefile syntax. Signed-off-by:

We can only use I2C support in frame buffer drivers if Either I2C is built-in, or both I2C and the driver itself are loadable modules. Fix this dependency for MB862XX and CyberPro frame buffers. Signed-off-by:

The sh_mobile_lcdcfb driver calls interfaces provided by the corresponding "meram" helper. This fails if meram is a module but lcdcfb is built-in. To work around it, this uses special Kconfig magic to only allow lcdcfb to be built if a) both are modules, b) meram is built-in, or c) meram is disabled and the helpers stubbed out Changing meram from 'y' to 'm' now forces clcd to be a module as well, which seems to be the desired behavior.

Sparse complains about using zero instead of NULL for pointers. Probably, if we enabled the warning, then GCC would complain about the unused initializers. I've just removed them. Smatch complains that we first check if "fbi" is NULL and then dereference it in the error handling. It turns out that "fbi" can't be NULL so I've removed the check. Signed-off-by:

In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it. This patch logs the error, before returning the error code to the caller. Reported-by:

Every event in the perf-kvm has a 'stats' structure, which contains max/min/average/etc times of handling this event. The problem is that the 'perf-kvm stat report' command always shows that 'min time' is 0us for every event. Example: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 0us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 0us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 0us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 0us 44us 16.49us ( +- 38.20% ) [..] This happens because the 'stats' structure is not initialized and stats->min equals to 0. Lets initialize the structure for every event after its allocation using init_stats() function. This initializes stats->min to -1 and makes 'Min time' statistics counting work: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 6us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 7us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 1us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 1us 44us 16.49us ( +- 38.20% ) [..] Signed-off-by:Alexander Yarygin <yarygin@linux.vnet.ibm.com> Signed-off-by:
