2008-08-15kexec jump: rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZEHuang Ying1-1/+1
Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control page is used for not only code on some platform. For example in kexec jump, it is used for data and stack too.

2008-08-11sh: Provide a FLAT_PLAT_INIT() definition.Takashi YOSHII1-0/+7
SH needs this in order to make sure that r4 has a sane value at process entry time, which the libc expects has already been taken care of. Fixes random crashes in flat binaries. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-11video: export sh_mobile_lcdc panel sizeMagnus Damm3-0/+18
Export the LCD panel size for sh_mobile_lcdc boards. This allows us to perform dpi and screen aspect ratio calculations in user space. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-11sh: select memchunk size using kernel cmdlineMagnus Damm1-0/+27
Allow user to pass parameters on kernel command line to override default size for physically contiguous memory buffers. The default VPU buffer size is too small for VGA harware encoding, but instead of just bumping up the number we allow the user to override the default size using the command line. Supports SuperH Mobile hardware blocks such as VEU, VPU and CEU. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-11sh: export sh7723 VEU as VEU2HMagnus Damm1-2/+2
Export sh7723 VEU hardware blocks as VEU2H. The sh7723 VEU2H differs a bit from the sh7722 VEU so use different names for our UIO devices. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-08-11sh: Disable 64kB hugetlbpage size when using 64kB PAGE_SIZE.Paul Mundt1-0/+2
Presently we oops in mm/hugetlb.c:1325, which is the order == 0 test in hugetlb_add_hstate() called at initialization time. So, disable 64kB huge pages when we're using a 64kB PAGE_SIZE. On most parts this will force the default to be 1MB huge pages. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-08-04add addrespace definition for sh2a.Takashi Yoshii1-0/+10
Newfile: arch/sh/include/cpu-sh2a/cpu/addrspace.h This file seems had be removed to use fallback (cpu-common/cpu/addrspace.h), but, I'd like to add sh2a specific file here, because 1. the values defined there are not suitable for sh2a. 2. I don't think there is "common" definition for these values. Values are chosen by consideration of followings... P1 is 0. perhaps no question. P2 is from hardware manual, which says no-cache area starts at 20000000. It means that P? space size=20000000. P3 is P2+size since asm/ptrace.h uses P3 as a end of P2. P4 is P3+size since asm/fixup.h uses P4 as a end of P3. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-04sh: Kill off ARCH_SUPPORTS_AOUT and remnants of a.out support.Paul Mundt2-23/+0
SH never really supported a.out, so this was all just copied over blindly from x86 way back when. As we don't reference linux/a.out.h anywhere in the tree, these can now safely be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-04sh: define GENERIC_HARDIRQS_NO__DO_IRQ.Paul Mundt1-0/+3

2008-08-01sh: Make syscall tracer use tracehook notifiers, add TIF_NOTIFY_RESUME.Paul Mundt7-158/+174
This follows the changes in commits: 7d6d637dac2050f30a1b57b0a3dc5de4a10616ba 4f72c4279eab1e5f3ed1ac4e55d4527617582392 on powerpc. Adding in TIF_NOTIFY_RESUME, and cleaning up the syscall tracing to be more generic. This is an incremental step to turning on tracehook, as well as unifying more of the ptrace and signal code across the 32/64 split. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-08-01sh: ptrace single stepping cleanups.Paul Mundt3-140/+39
This converts the single stepping done by sh/sh64 ptrace implementations to use the generic user_enable/disable_single_step(), and subsequently rips out a lot of ptrace request cases that are now handled generically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
