The kernel does not compile for my ARM926EJ-S system U300 due to the isb instruction inserted in generic assember statement from commit 8925ec4c, "ARM: 6385/1: setup: detect aliasing I-cache when D-cache is non-aliasing" hey the isb is only available when assembling for v7 so let's use the generic isb() macro from setup.h instead.

copy_to_user_page can be used by access_process_vm to write to an executable page of a process using a mapping acquired by kmap. For systems with I-cache aliasing, flushing the I-cache using the Kernel mapping may leave stale data in the I-cache if the user mapping is of a different colour. This patch introduces a flush_icache_alias function to flush.c, which calls flush_icache_range with a mapping of the specified colour. flush_ptrace_access is then modified to call this new function instead of coherent_kern_range in the case of an aliasing I-cache and a non-aliasing D-cache.

Currently, the Kernel assumes that if a CPU has a non-aliasing D-cache then the I-cache is also non-aliasing. This may not be true on ARM cores from v6 onwards, which may have aliasing I-caches but non-aliasing D-caches. This patch adds a cpu_has_aliasing_icache function, which is called from cacheid_init and adds CACHEID_VIPT_I_ALIASING to the cacheid when appropriate. A utility macro, icache_is_vipt_aliasing(), is also provided. Signed-off-by: NWill Deacon <will.deacon@arm.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Do this by adding flush_icache_all to cache_fns for ARMv6 and 7. As flush_icache_all may neeed to be called from flush_kern_cache_all, add it as the first entry in the cache_fns.

UP systems do not implement all the instructions that SMP systems have, so in order to boot a SMP kernel on a UP system, we need to rewrite parts of the kernel. Do this using an 'alternatives' scheme, where the kernel code and data is modified prior to initialization to replace the SMP instructions, thereby rendering the problematical code ineffectual. We use the linker to generate a list of 32-bit word locations and their replacement values, and run through these replacements when we detect a UP system.

由 Tejun Heo 提交于
libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

Commit e40cc4bd introduced a build breakage if CONFIG_SMP is undefined. This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.
