2008-02-05[S390] Implement ext2_find_next_bit.Heiko Carstens
Fixes this compile error: fs/ext4/mballoc.c: In function 'ext4_mb_generate_buddy': fs/ext4/mballoc.c:954: error: implicit declaration of function 'generic_find_next_le_bit' Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-02-05[S390] Cleanup & optimize bitops.Martin Schwidefsky
The bitops header is now a bit shorter and easier to understand since it uses less inline assembly. It requires some tricks to persuade the compiler to generate decent code. The ffz/ffs functions now use the _zb_findmap/_sb_findmap table as well. With this cleanup the new bitops for ext4 can be implemented with a few lines, instead of another large inline assembly.

2008-02-04[ARM] 4822/1: RealView: Change the REALVIEW_MPCORE configuration optionCatalin Marinas
This patch changes the REALVIEW_MPCORE configuration option to REALVIEW_EB_ARM11MP since this is only specific to RealView/EB. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4819/1: RealView: Fix entry-macro.S to work with multiple platformsCatalin Marinas
This patch modifies the get_irqnr_preamble macro to work with multiple platforms at run-time by reading the address of the GIC controller from the gic_cpu_base_addr variable. This variable is defined in core.c and intialised in realview_eb.c (gic_init_irq). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4818/1: RealView: Add core-tile detectionCatalin Marinas
This patch adds the core-tile detection and only enables devices if the corresponding tile is present. It currently detects the ARM11MPCore via the core_tile_eb11mp() macro. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.hCatalin Marinas
This patch moves the platform specific definitions from platform.h into the board-eb.h file. It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files.

2008-02-04[ARM] 4815/1: RealView: Add clockevents suport for the local timersCatalin Marinas
This patch registers the local timers on ARM11MPCore as clock event devices. The clock device can be set up as periodic or oneshot. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCoreCatalin Marinas
This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer.

2008-02-04[ARM] 4813/1: Add SMP helper functions for clockevents supportCatalin Marinas

Rather than unconditionally reloading cr3, only do so if the pud we're updating is within the active pgd. This eliminates TLB flushes most of the time. The performance-critical uses of pud_clear are during execve and exit, but in those cases cr3 is referring to some other pagetable. The only other use of pud_clear is during a large (1Gbyte+) munmap, and those are sufficiently rare that a couple of cr3 reloads won't hurt.

2008-02-04x86: unify CPU feature string namesH. Peter Anvin
Move the CPU feature string names to a separate file (common to 32 and 64 bits); additionally, make <asm/cpufeature.h> includable by host code in preparation for including the CPU feature strings in the boot code.

2008-02-04x86: reintroduce volatile keyword in prototype to clflush()H. Peter Anvin
The volatile keyword was removed from the clflush() prototype in commit e34907ae180f4fe6c28bb4516c679c2f81b0c9ed; the comment there states: x86: remove volatile keyword from clflush. the p parameter is an explicit memory reference, and is enough to prevent gcc to being nasty here. The volatile seems completely not needed. This reflects incorrect understanding of the function of the volatile keyword there. The purpose of the volatile keyword is informing gcc that it is safe to pass a volatile pointer to this function. Signed-off-by: H.
