Richard Purdie	1c9d3df5e8	[ARM] 4078/1: Fix ARM copypage cache coherency problems ... If PG_dcache_dirty is set for a page, we need to flush the source page before performing any copypage operation using a different virtual address. This fixes the copypage implementations for XScale, StrongARM and ARMv6. This patch fixes segmentation faults seen in the dynamic linker under the usage patterns in glibc 2.4/2.5.

Russell King	ad1ae2fe7f	[ARM] Unuse another Linux PTE bit ... L_PTE_ASID is not really required to be stored in every PTE, since we can identify it via the address passed to set_pte_at(). So, create set_pte_ext() which takes the address of the PTE to set, the Linux PTE value, and the additional CPU PTE bits which aren't encoded in the Linux PTE value.

Russell King	1b2e2b73b4	[ARM] Cleanup arch/arm/mm a little ... Move top_pmd into arch/arm/mm/mm.h - nothing outside arch/arm/mm references it. Move the repeated definition of TOP_PTE into mm/mm.h, as well as a few function prototypes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>	19 years ago
Russell King	f8f98a9335	[PATCH] ARM: Fix Xscale copy_page implementation ... The ARM copypage changes in 2.6.12-rc4-git1 removed the preempt locking from the copypage functions which broke the XScale implementation. This patch fixes the locking on XScale and removes the now unneeded minicache code. Signed-off-by: Russell King <rmk@arm.linux.org.uk> Checked-by: Richard Purdie	20 years ago
