2012-10-09mm: hugetlb: add arch hook for clearing page flags before entering poolWill Deacon1-0/+4
The core page allocator ensures that page flags are zeroed when freeing pages via free_pages_check. A number of architectures (ARM, PPC, MIPS) rely on this property to treat new pages as dirty with respect to the data cache and perform the appropriate flushing before mapping the pages into userspace. This can lead to cache synchronisation problems when using hugepages, since the allocator keeps its own pool of pages above the usual page allocator and does not reset the page flags when freeing a page into the pool. This patch adds a new architecture hook, arch_clear_hugepage_flags, so that architectures which rely on the page flags being in a particular state for fresh allocations can adjust the flags accordingly when a page is freed into the pool.

This is a preparatory patch for the introduction of NT_SIGINFO elf note. Make the location of compat_siginfo_t uniform across eight architectures which have it. Now it can be pulled in by including asm/compat.h or linux/compat.h. Most of the copies are verbatim. compat_uid[32]_t had to be replaced by __compat_uid[32]_t. compat_uptr_t had to be moved up before compat_siginfo_t in asm/compat.h on a several architectures (tile already had it moved up). compat_sigval_t had to be relocated from linux/compat.h to asm/compat.h.

git://git.infradead.org/users/dhowells/linux-headers Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare2-2/+2
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space.

2012-09-14MIPS: Malta: Remove RTC Data Mode bootstrap breakageMaciej W. Rozycki1-5/+0
YAMON requires and enforces the RTC Data Mode (Register B, DM bit) to binary, that is the bit is set every time the board goes through the firmware bootstrap sequence. Likewise its calendar manipulation commands interpret or set the RTC registers unconditionally as binary, never actually checking what the value of the DM bit is, under the (correct) assumption that it has been previously set, to indicate the binary mode. A change to Linux a while ago however introduced a platform-specific tweak that clears that bit and therefore forces the data mode to BCD. This causes clock corruption and misinterpretation that has to be fixed up by user-mode tools in system startup scripts as the initial clock is often incorrect according to the BCD interpretation forced. This change removes the hack; a comment included refers to alarm code, but even if it was broken at one point by requiring the BCD mode, it should have been trivially corrected and even if not, given how rarely the alarm feature is used, that was not really a reasonable justification to break the system clock that is indeed used by virtually everything. And either way the alarm code has been since fixed anyway. Signed-off-by: Maciej W.

2012-08-17MIPS: Synchronize MIPS count one CPU at a timeJayachandran C3-21/+17
The current implementation of synchronise_count_{master,slave} blocks slave CPUs in early boot until all of them come up. This no longer works because blocking a CPU with interrupts off after notifying the CPU to be online causes problems with the current kernel. Specifically, after the workqueue changes (commit a08489c569dc1 "Pull workqueue changes from Tejun Heo") the CPU_ONLINE notification callback workqueue_cpu_up_callback() will hang on wait_for_completion(&idle_rebind.done), if the slave CPUs are blocked for synchronize_count_slave(). The changes are to update synchronize_count_{master,slave}() to handle one CPU at a time and to call synchronise_count_master() in __cpu_up() so that the CPU_ONLINE notification goes out only after the COP0 COUNT register is synchronized.

2012-08-17MIPS: BCM63xx: Fix SPI message control register handling for BCM6338/6348.Florian Fainelli3-3/+16
BCM6338 and BCM6348 have a message control register width of 8 bits, instead of 16-bits like what the SPI driver assumes right now. Also the SPI message type shift value of 14 is actually 6 for these SoCs. This resulted in transmit FIFO corruption because we were writing 16-bits to an 8-bits wide register, thus spanning on the first byte of the transmit FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo(). Fix this by passing the message control register width and message type shift through platform data back to the SPI driver so that it can use it properly.
