* x86: unify ioremap_32 and _64Thomas Gleixner2008-01-30
| | | | | | | | Unify the now identical ioremap_32.c and ioremap_64.c into the same ioremap.c file. No code changed. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: use remove_vm_are in ioremap_32 error pathThomas Gleixner2008-01-30
| | | | | | | | | When ioremap_page_range fails, then we can use remove_vm_area instead of vunmap safely. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: switch to change_page_attr_addr in ioremap_32.cThomas Gleixner2008-01-30
| | | | | | | | | | Use change_page_attr_addr() instead of change_page_attr(), which simplifies the code significantly and matches the 64bit implementation. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: make c_p_a unconditional in ioremapThomas Gleixner2008-01-30
| | | | | | | | | | Make c_p_a unconditional for ioremap and iounmap. This ensures complete consistency of the flags which are handed to ioremap_page_range and the real flags in the mappings. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: cleanup ioremap includesThomas Gleixner2008-01-30
| | | | | | | | | Get rid of the douplicate define of ISA_START/END_ADDRESS and use the same headers in 32 and 64 bit code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: style cleanup of ioremap codeThomas Gleixner2008-01-30
| | | | | | | | Fix the coding style before going further. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: fix ioremap pgprot inconsistencyThomas Gleixner2008-01-30
| | | | | | | | | | | | | The pgprot flags which are handed into ioremap_page_range() are different to those which are set in change_page_attr(). The ioremap_page_range flags are executable, while the c_p_a flags are not. Also make the mappings global (which is a NOP currently on 32bit, although CPUs from PPRO+ onwards support it, but that's a separate fix.)

* x86: make early_ioremap_debug early_paramHuang, Ying2008-01-30
| | | | | | | | | | This patch makes "early_ioremap_debug" a early parameter, because "early_ioreamp/early_iounmap" is only used during early boot stage. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* x86 32-bit boot: rename bt_ioremap() to early_ioremap()Huang, Ying2008-01-30
| | | | | | | | | | | This patch renames bt_ioremap to early_ioremap, which is used in x86_64. This makes it easier to merge i386 and x86_64 usage.

* i386 boot: replace boot_ioremap with enhanced bt_ioremap - enhance bt_ioremapHuang, Ying2008-01-30
| | | | | | | | | | | | This patch makes it possible for bt_ioremap() to be used before paging_init(), via providing an early implementation of set_fixmap() that can be used before paging_init(). This way boot_ioremap() can be replaced by bt_ioremap().

* x86: set strong uncacheable where UC is really desiredSiddha, Suresh B2008-01-30
| | | | | | | | | | | | Also use _PAGE_PWT for all the mappings which need uncache mapping. Instead of existing PAT2 which is UC- (and can be overwritten by MTRRs), we now use PAT3 which is strong uncacheable. This makes it consistent with pgprot_noncached() Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
