2017-02-28ARM: 8655/1: improve NOMMU definition of pgprot_*()Arnd Bergmann1-3/+3
The tegra DRM driver produces a harmless warning when built for NOMMU: drivers/gpu/drm/tegra/gem.c: In function 'tegra_drm_mmap': drivers/gpu/drm/tegra/gem.c:508:12: unused variable 'prot' This is because pgprot_writecombine() on ARM returns a constant and ignores its argument. The version in asm-generic doesn't have that problem, so let's use that one instead. We don't actually care about the value on NOMMU, and this is consistent with what some other architectures do.

2017-02-28ARM: 8650/1: module: handle negative R_ARM_PREL31 addends correctlyArd Biesheuvel1-2/+11
According to the spec 'ELF for the ARM Architecture' (IHI 0044E), addends for R_ARM_PREL31 relocations are 31-bit signed quantities, so we need to sign extend the value to 32 bits before it can be used as an offset in the calculation of the relocated value. We have not been bitten by this because these relocations are usually emitted against the start of a section, which means the addends never assume negative values in practice. But it is a bug nonetheless, so fix it. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2017-02-28ARM: 8646/1: mmu: decouple VECTORS_BASE from KconfigAfzal Mohammed4-5/+9
For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro definition will suffice. For no-MMU, exception base address is dynamically determined in subsequent patches. To preserve bisectability, now make the macro applicable for no-MMU scenario too. Thanks to 0-DAY kernel test infrastructure that found the bisectability issue. This macro will be restricted to MMU case upon dynamically determining exception base address for no-MMU. Once exception address is handled dynamically for no-MMU, VECTORS_BASE can be removed from Kconfig.

2017-02-28ARM: 8637/1: Adjust memory boundaries after reservationsLaura Abbott2-3/+12
adjust_lowmem_bounds is responsible for setting up the boundary for lowmem/highmem. This needs to be setup before memblock reservations can occur. At the time memblock reservations can occur, memory can also be removed from the system. The lowmem/highmem boundary and end of memory may be affected by this but it is currently not recalculated. On some systems this may be harmless, on others this may result in incorrect ranges being passed to the main memory allocator. Correct this by recalculating the lowmem/highmem boundary after all reservations have been made.

2017-02-28mac80211: use driver-indicated transmitter STA only for data framesJohannes Berg1-7/+9
When I originally introduced using the driver-indicated station as an optimisation to avoid the hashtable lookup/iteration, of course it wasn't intended to really functionally change anything. I neglected, however, to take into account VLAN interfaces, which have the property that management and data frames are handled differently: data frames go directly to the station and the VLAN while management frames continue to be processed over the underlying/associated AP-type interface. As a consequence, when a driver used this optimisation for management frames and the user enabled VLANs, my change broke things since any management frames, particularly disassoc/deauth, were missed by hostapd. Fix this by restoring the original code path for non-data frames, they aren't critical for performance to begin with. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=194713. Big thanks goes to Jarek who bisected the issue and provided a very detailed bug report, including the crucial information that he was using VLANs in his configuration.

This patch makes arch-independent testcases for RODATA. Both x86 and x86_64 already have testcases for RODATA, But they are arch-specific because using inline assembly directly. And cacheflush.h is not a suitable location for rodata-test related things. Since they were in cacheflush.h, If someone change the state of CONFIG_DEBUG_RODATA_TEST, It cause overhead of kernel build.

2017-02-27mm: add new mmgrab() helperVegard Nossum40-43/+65
Apart from adding the helper function itself, the rest of the kernel is converted mechanically using: git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/' git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own. (Michal Hocko provided most of the kerneldoc comment.)

2017-02-27checkpatch: warn when formats use %Z and suggest %zAlexey Dobriyan1-9/+20
vsnprintf extension %Z<foo> is non-standard C. Suggest the use of %z instead. Miscellanea: - Correct the misuse of type string PRINTF_0xDECIMAL type strings are supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the type check in case I forget this again sometime in the future. - Improve the mechanism to find these defects so all 3 current checks are done on the format string [joe@perches.com: correct the misuse of type string PRINTF_0xDECIMAL, improve the mechanism to find these defects] Link: http://lkml.kernel.org/r/4e3ad74b0c9dc229b06018a2d79655308ddbbebd.1484014173.git.joe@perches.com Link: http://lkml.kernel.org/r/20170109235955.GA6787@avx2 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan79-201/+187
Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
