powerpc: Delete non-required instances of include

2014-01-15T02:46:44Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. The one instance where we add an include for init.h covers off a case where that file was implicitly getting it from another header which itself didn't need it.

powerpc/kgdb: use DEFINE_PER_CPU to allocate kgdb's thread_info

2013-10-18T23:38:10Z

Use DEFINE_PER_CPU to allocate thread_info statically instead of kmalloc(). This can avoid introducing more memory check codes. Signed-off-by: Tiejun Chen [scottwood@freescale.com: wrapped long line] Signed-off-by: Scott Wood

powerpc/kgdb: Removed kmalloc returned value cast

Merge "merge" branch to bring in various bug fixes that are going into 3.8

powerpc: kernel/kgdb.c: Fix memory leakage

the variable backup_current_thread_info isn't freed before existing the function. Signed-off-by: Cong Ding Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix typo in breakpoint kgdb code.

2013-01-15T18:25:46Z

Currently we are getting: arch/powerpc/kernel/kgdb.c: In function 'kgdb_arch_exit': arch/powerpc/kernel/kgdb.c:492:2: error: '__debugger_breakx_match' undeclared (first use in this function) arch/powerpc/kernel/kgdb.c:492:2: note: each undeclared identifier is reported only once for each function it appears in Fix the typo.

powerpc: Hardware breakpoints rewrite to handle non DABR breakpoint registers

2013-01-10T06:01:44Z

This is a rewrite so that we don't assume we are using the DABR throughout the code. We now use the arch_hw_breakpoint to store the breakpoint in a generic manner in the thread_struct, rather than storing the raw DABR value. The ptrace GET/SET_DEBUGREG interface currently passes the raw DABR in from userspace. We keep this functionality, so that future changes (like the POWER8 DAWR), will still fake the DABR to userspace. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc/kgdb: Restore current_thread_info properly

2012-08-24T10:26:06Z

For powerpc BooKE and e200, singlestep is handled on the critical/dbg exception stack. This causes current_thread_info() to fail for kgdb internal, so previously We work around this issue by copying the thread_info from the kernel stack before calling kgdb_handle_exception, and copying it back afterwards. But actually we don't do this properly. We should backup current_thread_info then restore that when exit. Signed-off-by: Tiejun Chen Signed-off-by: Benjamin Herrenschmidt

powerpc/kgdb: Bail out of KGDB when we've been triggered

2012-08-24T10:26:05Z

We need to skip a breakpoint exception when it occurs after a breakpoint has already been removed. Signed-off-by: Tiejun Chen Signed-off-by: Benjamin Herrenschmidt

powerpc/kgdb: Do not set kgdb_single_step on ppc

2012-08-24T10:26:05Z

The kgdb_single_step flag has the possibility to indefinitely hang the system on an SMP system. The x86 arch have the same problem, and that problem was fixed by commit 8097551d9ab9b9e3630(kgdb,x86: do not set kgdb_single_step on x86). This patch does the same behaviors as x86's patch.
